UNRAID - How to Shrink an Array and Create a Cache Pool

so a couple months ago I got into unraid so a couple months ago I got into unraid and when I first kind of showed my setup and when I first kind of showed my setup and when I first kind of showed my setup a couple of you pointed out some of the a couple of you pointed out some of the a couple of you pointed out some of the noobish mistakes that I initially made noobish mistakes that I initially made noobish mistakes that I initially made and the primary mistakes that I made was and the primary mistakes that I made was and the primary mistakes that I made was one I put an nvme drive that should have one I put an nvme drive that should have one I put an nvme drive that should have been used as a Cash Drive in my array been used as a Cash Drive in my array been used as a Cash Drive in my array with all of my other drives and two I with all of my other drives and two I with all of my other drives and two I had a misunderstanding of the had a misunderstanding of the had a misunderstanding of the possibilities and potential that actual possibilities and potential that actual possibilities and potential that actual file shares had particularly the app file shares had particularly the app file shares had particularly the app data folder I went ahead created my own data folder I went ahead created my own data folder I went ahead created my own Docker folder only included drive before Docker folder only included drive before Docker folder only included drive before that Docker folder to be one of the that Docker folder to be one of the that Docker folder to be one of the drives on the array that I wanted which drives on the array that I wanted which drives on the array that I wanted which was the nvme overall it just was not was the nvme overall it just was not was the nvme overall it just was not efficient or how it should have been at efficient or how it should have been at efficient or how it should have been at all I've already started the process of all I've already started the process of all I've already started the process of fixing these issues if I go over here to fixing these issues if I go over here to fixing these issues if I go over here to main so far the one thing I did was main so far the one thing I did was main so far the one thing I did was actually shrink my array and rebuild my actually shrink my array and rebuild my actually shrink my array and rebuild my parody so you can see I now have a six parody so you can see I now have a six parody so you can see I now have a six instead of seven this right here this instead of seven this right here this instead of seven this right here this unassigned Drive was part of this array unassigned Drive was part of this array unassigned Drive was part of this array right here initially what we're going to right here initially what we're going to right here initially what we're going to be doing in this video is one continue be doing in this video is one continue be doing in this video is one continue fixing my little kind of noob mistakes fixing my little kind of noob mistakes fixing my little kind of noob mistakes here and setting up a new cache and here and setting up a new cache and here and setting up a new cache and actually upgrading to this right here actually upgrading to this right here actually upgrading to this right here this is a move speed two terabyte drive this is a move speed two terabyte drive this is a move speed two terabyte drive they sent this over specifically for they sent this over specifically for they sent this over specifically for this video supposedly supports speeds of this video supposedly supports speeds of this video supposedly supports speeds of 7000 megabytes a second so I am excited 7000 megabytes a second so I am excited 7000 megabytes a second so I am excited to go ahead and throw that in there and to go ahead and throw that in there and to go ahead and throw that in there and one of the things that just makes unraid one of the things that just makes unraid one of the things that just makes unraid really cool is how actually kind of easy really cool is how actually kind of easy really cool is how actually kind of easy it is to fix this actually shrinking an it is to fix this actually shrinking an it is to fix this actually shrinking an array with other types of raid

array with other types of raid array with other types of raid configurations are much more difficult configurations are much more difficult configurations are much more difficult than the process that I've done so far than the process that I've done so far than the process that I've done so far with this if we go over here to the with this if we go over here to the with this if we go over here to the shrink array documentation so there are shrink array documentation so there are shrink array documentation so there are a couple ways to do this the method I a couple ways to do this the method I a couple ways to do this the method I used is the remove Drive-In rebuild used is the remove Drive-In rebuild used is the remove Drive-In rebuild parody and the procedures right here it parody and the procedures right here it parody and the procedures right here it is fairly simple all I did was first is fairly simple all I did was first is fairly simple all I did was first changed my actual Docker share so it changed my actual Docker share so it changed my actual Docker share so it didn't include that new or that uh nvme didn't include that new or that uh nvme didn't include that new or that uh nvme drive that was in my array from there I drive that was in my array from there I drive that was in my array from there I backed up all my docker configuration backed up all my docker configuration backed up all my docker configuration files into a folder right here on my files into a folder right here on my files into a folder right here on my desktop I could have just moved them desktop I could have just moved them desktop I could have just moved them over to the other drives but this is over to the other drives but this is over to the other drives but this is going to work fine and then I went under going to work fine and then I went under going to work fine and then I went under main took a screenshot of my kind of main took a screenshot of my kind of main took a screenshot of my kind of array configuration because you don't array configuration because you don't array configuration because you don't want to accidentally put a different want to accidentally put a different want to accidentally put a different drive as your parity drive because that drive as your parity drive because that drive as your parity drive because that parody Drive is going to get completely parody Drive is going to get completely parody Drive is going to get completely wiped so take that screenshot make sure wiped so take that screenshot make sure wiped so take that screenshot make sure everything kind of matches up there everything kind of matches up there everything kind of matches up there under retain current configuration under retain current configuration under retain current configuration selecting all that is a very helpful selecting all that is a very helpful selecting all that is a very helpful thing to do and after everything was thing to do and after everything was thing to do and after everything was looking good I went ahead started the looking good I went ahead started the looking good I went ahead started the array and then I let it rebuild the array and then I let it rebuild the array and then I let it rebuild the parity and that's what it's been doing parity and that's what it's been doing parity and that's what it's been doing for the last like eight hours or so for the last like eight hours or so for the last like eight hours or so takes quite a while to do that now there takes quite a while to do that now there takes quite a while to do that now there is a risk to that while it's rebuilding is a risk to that while it's rebuilding is a risk to that while it's rebuilding that parody If you just so happen to be that parody If you just so happen to be that parody If you just so happen to be incredibly unlucky in a drive fails you incredibly unlucky in a drive fails you incredibly unlucky in a drive fails you are going to lose data but they do have are going to lose data but they do have are going to lose data but they do have a clear drive then remove Drive method a clear drive then remove Drive method a clear drive then remove Drive method right here that will prevent data loss right here that will prevent data loss right here that will prevent data loss now I am where I currently am and that now I am where I currently am and that now I am where I currently am and that is with this drive right here that I'm is with this drive right here that I'm is with this drive right here that I'm going to upgrade what another thing I going to upgrade what another thing I going to upgrade what another thing I need to do is with that if I go over need to do is with that if I go over need to do is with that if I go over here to docker and let's just say I open here to docker and let's just say I open here to docker and let's just say I open up overseer you can see if I go to more

up overseer you can see if I go to more up overseer you can see if I go to more settings Mount user Docker overseer I'm settings Mount user Docker overseer I'm settings Mount user Docker overseer I'm going to be switching all these back going to be switching all these back going to be switching all these back over to the app data share that you're over to the app data share that you're over to the app data share that you're actually supposed to use and which is actually supposed to use and which is actually supposed to use and which is kind of the default but I'm going to do kind of the default but I'm going to do kind of the default but I'm going to do that after I add this new drive and set that after I add this new drive and set that after I add this new drive and set up that share so if I go over here to up that share so if I go over here to up that share so if I go over here to shares this app data share is going to shares this app data share is going to shares this app data share is going to be set on a cash pool which is the be set on a cash pool which is the be set on a cash pool which is the method that I should have used when method that I should have used when method that I should have used when initially adding that nvme SSD so with initially adding that nvme SSD so with initially adding that nvme SSD so with that I do actually need to shut this that I do actually need to shut this that I do actually need to shut this down so I can upgrade that so let's go down so I can upgrade that so let's go down so I can upgrade that so let's go over here let's go shut down just for over here let's go shut down just for over here let's go shut down just for the record I too want to uh kind of flex the record I too want to uh kind of flex the record I too want to uh kind of flex my uptime going on 80 days which is my uptime going on 80 days which is my uptime going on 80 days which is pretty good I got a UPS in there and all pretty good I got a UPS in there and all pretty good I got a UPS in there and all that so that was definitely uh helpful that so that was definitely uh helpful that so that was definitely uh helpful in that regard so main shutdown proceed in that regard so main shutdown proceed in that regard so main shutdown proceed let's go grab the nas all right we got let's go grab the nas all right we got let's go grab the nas all right we got our Nas here if you're not aware I'm our Nas here if you're not aware I'm our Nas here if you're not aware I'm using the terror master I forgot the using the terror master I forgot the using the terror master I forgot the specific model but it's the six Bay kind specific model but it's the six Bay kind specific model but it's the six Bay kind of desktop Tower Guy this is the nas of desktop Tower Guy this is the nas of desktop Tower Guy this is the nas that I use primarily for media so movies that I use primarily for media so movies that I use primarily for media so movies TV shows things like that I use Synology TV shows things like that I use Synology TV shows things like that I use Synology for like personal photos documents you for like personal photos documents you for like personal photos documents you know now check this out this is an LTT know now check this out this is an LTT know now check this out this is an LTT screwdriver I actually made this one the screwdriver I actually made this one the screwdriver I actually made this one the kind of custom color scheme here at the kind of custom color scheme here at the kind of custom color scheme here at the LT Expo super cool let's move this down LT Expo super cool let's move this down LT Expo super cool let's move this down a little bit so you all can see what's a little bit so you all can see what's a little bit so you all can see what's going on here there we go here is the going on here there we go here is the going on here there we go here is the Terra master we're gonna unplug our USB

Terra master we're gonna unplug our USB Terra master we're gonna unplug our USB and then unscrew this there we go let's and then unscrew this there we go let's and then unscrew this there we go let's pop off this side panel I forgot where pop off this side panel I forgot where pop off this side panel I forgot where the SSD is hopefully it is like right the SSD is hopefully it is like right the SSD is hopefully it is like right here and look at that it is I got a here and look at that it is I got a here and look at that it is I got a system memory module right here I should system memory module right here I should system memory module right here I should probably upgrade it so now we're gonna probably upgrade it so now we're gonna probably upgrade it so now we're gonna get our two terabyte SSD out of here get our two terabyte SSD out of here get our two terabyte SSD out of here some Tiger Eyes on it now I do have two some Tiger Eyes on it now I do have two some Tiger Eyes on it now I do have two slots here hopefully I'm going to be slots here hopefully I'm going to be slots here hopefully I'm going to be able to put another two terabyte SSD in able to put another two terabyte SSD in able to put another two terabyte SSD in here but this little 128 gig kind of here but this little 128 gig kind of here but this little 128 gig kind of sucks it overheats all the time so I'm sucks it overheats all the time so I'm sucks it overheats all the time so I'm just going to remove it there we go now this thing did come with there we go now this thing did come with a heat sink I'm curious to if it will a heat sink I'm curious to if it will a heat sink I'm curious to if it will fit I'll use this one this one's a fit I'll use this one this one's a fit I'll use this one this one's a little bit better and I think it will little bit better and I think it will little bit better and I think it will fit perfect so let's get this thermal fit perfect so let's get this thermal fit perfect so let's get this thermal pad here as I can pad here as I can pad here as I can damn that's pretty good and then pop it damn that's pretty good and then pop it damn that's pretty good and then pop it on our hoping for the best on our hoping for the best on our hoping for the best here we go here we go here we go I mean it looks pretty solid to me did I I mean it looks pretty solid to me did I I mean it looks pretty solid to me did I do it on the right side yeah I did do it on the right side yeah I did do it on the right side yeah I did that's good it has a sticker on the back that's good it has a sticker on the back that's good it has a sticker on the back and on the front you can see the and on the front you can see the and on the front you can see the confusion all right we're looking good so now I'm all right we're looking good so now I'm gonna go plug it back in gonna go plug it back in gonna go plug it back in oh oh oh can't forget this kind of important for can't forget this kind of important for can't forget this kind of important for unwrite all right we are up we are good unwrite all right we are up we are good unwrite all right we are up we are good to go I was paying it to make sure it to go I was paying it to make sure it to go I was paying it to make sure it worked and we're in the available array worked and we're in the available array worked and we're in the available array page now this is where I made the page now this is where I made the page now this is where I made the mistake when I first set it up because mistake when I first set it up because mistake when I first set it up because right here I clicked on this and I added

right here I clicked on this and I added right here I clicked on this and I added it just like that you do not want to do it just like that you do not want to do it just like that you do not want to do that let's leave that unassigned here I that let's leave that unassigned here I that let's leave that unassigned here I do want to add a pool do want to add a pool do want to add a pool this is going to be a cash pool one slot this is going to be a cash pool one slot this is going to be a cash pool one slot let's go ahead and add that and then let's go ahead and add that and then let's go ahead and add that and then scroll on down here our cache is going scroll on down here our cache is going scroll on down here our cache is going to be assigned to the drive we just to be assigned to the drive we just to be assigned to the drive we just installed and that looks A-Okay to me so installed and that looks A-Okay to me so installed and that looks A-Okay to me so we are now going to start it up with a we are now going to start it up with a we are now going to start it up with a actual Drive Associated to cash and I actual Drive Associated to cash and I actual Drive Associated to cash and I didn't look too far into it but it didn't look too far into it but it didn't look too far into it but it should be fairly easy to add a second should be fairly easy to add a second should be fairly easy to add a second two terabyte Cash Drive to the same pool two terabyte Cash Drive to the same pool two terabyte Cash Drive to the same pool but again I don't know and I will also but again I don't know and I will also but again I don't know and I will also note that if I'm doing anything that note that if I'm doing anything that note that if I'm doing anything that could be done better or more efficient could be done better or more efficient could be done better or more efficient whatever just let me know whatever just let me know whatever just let me know it would be helpful now but of course it would be helpful now but of course it would be helpful now but of course before I could get too far this is before I could get too far this is before I could get too far this is unmountable unsupported partition layout unmountable unsupported partition layout unmountable unsupported partition layout we do need to format it one thing to we do need to format it one thing to we do need to format it one thing to note before I do that if I do go in here note before I do that if I do go in here note before I do that if I do go in here you have some additional options so the you have some additional options so the you have some additional options so the file system Auto I believe Auto is file system Auto I believe Auto is file system Auto I believe Auto is better FS we're going to leave it as better FS we're going to leave it as better FS we're going to leave it as that but here's where you get some that but here's where you get some that but here's where you get some information you can set up your smart information you can set up your smart information you can set up your smart settings so you're warning temperatures settings so you're warning temperatures settings so you're warning temperatures and all that but for now we're going to and all that but for now we're going to and all that but for now we're going to go ahead and format that so to do that go ahead and format that so to do that go ahead and format that so to do that we're just going to click this box that we're just going to click this box that we're just going to click this box that says yes format format and multiple says yes format format and multiple says yes format format and multiple disks okay and then I'm going to click disks okay and then I'm going to click disks okay and then I'm going to click on format to format that new 2 terabyte on format to format that new 2 terabyte on format to format that new 2 terabyte drive and you can see formatting and now drive and you can see formatting and now drive and you can see formatting and now we have a bunch of free space so there we have a bunch of free space so there we have a bunch of free space so there we go now I'm going to go over here to we go now I'm going to go over here to we go now I'm going to go over here to shares this Docker share right here I'm shares this Docker share right here I'm shares this Docker share right here I'm eventually going to get rid of my app eventually going to get rid of my app eventually going to get rid of my app data is the one that I am going to

data is the one that I am going to data is the one that I am going to assign to Cache so use cash Yes actually assign to Cache so use cash Yes actually assign to Cache so use cash Yes actually let's do only so all my Docker file let's do only so all my Docker file let's do only so all my Docker file files are going to be in Cache and one files are going to be in Cache and one files are going to be in Cache and one of the reasons why I like to do this is of the reasons why I like to do this is of the reasons why I like to do this is for example my Plex library or my Plex for example my Plex library or my Plex for example my Plex library or my Plex Docker folder it has tens of thousands Docker folder it has tens of thousands Docker folder it has tens of thousands of individual files totaling over I of individual files totaling over I of individual files totaling over I think about 10 gigabytes or so just think about 10 gigabytes or so just think about 10 gigabytes or so just imagine every time it needs to load a imagine every time it needs to load a imagine every time it needs to load a cover art a like a song anything like cover art a like a song anything like cover art a like a song anything like that it needs to find every individual that it needs to find every individual that it needs to find every individual file takes forever and that's one of the file takes forever and that's one of the file takes forever and that's one of the things that ends up making like the Plex things that ends up making like the Plex things that ends up making like the Plex UI and all that laggy so having that UI and all that laggy so having that UI and all that laggy so having that stuff on an SSD is way better slick cash stuff on an SSD is way better slick cash stuff on an SSD is way better slick cash pool that is our only one enable copy on pool that is our only one enable copy on pool that is our only one enable copy on right auto sounds good all this looks right auto sounds good all this looks right auto sounds good all this looks good so let's hit apply so with all that good so let's hit apply so with all that good so let's hit apply so with all that done I should be able to go into my done I should be able to go into my done I should be able to go into my network here so let's go right there network here so let's go right there network here so let's go right there let's go to our Network and then under let's go to our Network and then under let's go to our Network and then under hopkey media we have app data and I hopkey media we have app data and I hopkey media we have app data and I should be able to just drag and drop all should be able to just drag and drop all should be able to just drag and drop all of this right on into app data which it of this right on into app data which it of this right on into app data which it is working is working is working and just for a little before after we and just for a little before after we and just for a little before after we can see we're using just under four can see we're using just under four can see we're using just under four megabytes I'm gonna let that finish up megabytes I'm gonna let that finish up megabytes I'm gonna let that finish up here it might take a while and I've here it might take a while and I've here it might take a while and I've given this a refresh here you can see given this a refresh here you can see given this a refresh here you can see that it's starting to use space on that that it's starting to use space on that that it's starting to use space on that cache drive so it we're looking good so cache drive so it we're looking good so cache drive so it we're looking good so far and with the magic of editing far and with the magic of editing far and with the magic of editing everything is now moved over so I'm everything is now moved over so I'm everything is now moved over so I'm gonna now have to go through the painful gonna now have to go through the painful gonna now have to go through the painful process of actually fixing or editing

process of actually fixing or editing process of actually fixing or editing all these configurations let's start off all these configurations let's start off all these configurations let's start off with something easy such as audio with something easy such as audio with something easy such as audio bookshelf all I need to do go in user bookshelf all I need to do go in user bookshelf all I need to do go in user data audio books that's good this right data audio books that's good this right data audio books that's good this right here is not good so this is actually here is not good so this is actually here is not good so this is actually going to be in app data like that going to be in app data like that going to be in app data like that audiobook shelf and then switch out audiobook shelf and then switch out audiobook shelf and then switch out Docker for app data and then we should Docker for app data and then we should Docker for app data and then we should be able to just apply that and hopefully be able to just apply that and hopefully be able to just apply that and hopefully it just works there's only a couple it just works there's only a couple it just works there's only a couple containers I can think of where I'm containers I can think of where I'm containers I can think of where I'm going to have to go into the actual like going to have to go into the actual like going to have to go into the actual like through the container configuration to through the container configuration to through the container configuration to change that I think like my uh change that I think like my uh change that I think like my uh BitTorrent client might be one of them BitTorrent client might be one of them BitTorrent client might be one of them but the command changed successfully but the command changed successfully but the command changed successfully let's go done it's started up here so let's go done it's started up here so let's go done it's started up here so we'll let web UI and we are rocking so we'll let web UI and we are rocking so we'll let web UI and we are rocking so if I hit submit here we go beautiful and if I hit submit here we go beautiful and if I hit submit here we go beautiful and it looks like everything's in there it looks like everything's in there it looks like everything's in there don't judge my uh books I have in here don't judge my uh books I have in here don't judge my uh books I have in here I've gotten a lot of these ones for free I've gotten a lot of these ones for free I've gotten a lot of these ones for free and then just go through the process of and then just go through the process of and then just go through the process of doing this with all of these and I doing this with all of these and I doing this with all of these and I should be have it fixed to the point should be have it fixed to the point should be have it fixed to the point where everything's kind of default in where everything's kind of default in where everything's kind of default in the proper pools cash and all that how the proper pools cash and all that how the proper pools cash and all that how it is supposed to be all right there we it is supposed to be all right there we it is supposed to be all right there we go so I went through and I fixed all of go so I went through and I fixed all of go so I went through and I fixed all of those the only thing that I needed to those the only thing that I needed to those the only thing that I needed to like manually go and intervene with was like manually go and intervene with was like manually go and intervene with was the voltage VPN I needed to change my the voltage VPN I needed to change my the voltage VPN I needed to change my password and enable the plugin that password and enable the plugin that password and enable the plugin that didn't transfer with the config transfer didn't transfer with the config transfer didn't transfer with the config transfer but every thing now seems to be good to but every thing now seems to be good to but every thing now seems to be good to go I can enable all this real quick and go I can enable all this real quick and go I can enable all this real quick and if we go and head over to our shares we if we go and head over to our shares we if we go and head over to our shares we do have some unprotected files here I'll

do have some unprotected files here I'll do have some unprotected files here I'll figure out that in a minute but this figure out that in a minute but this figure out that in a minute but this right here Docker I am not going to be right here Docker I am not going to be right here Docker I am not going to be needing this anymore the share is empty needing this anymore the share is empty needing this anymore the share is empty so we have the option to delete it here so we have the option to delete it here so we have the option to delete it here so I'm going to go ahead and proceed so I'm going to go ahead and proceed so I'm going to go ahead and proceed with that there we go share Docker has with that there we go share Docker has with that there we go share Docker has been deleted done so now the only one been deleted done so now the only one been deleted done so now the only one that's kind of mine here is the data one that's kind of mine here is the data one that's kind of mine here is the data one for my media files now with all that I for my media files now with all that I for my media files now with all that I do hope you enjoyed this video unread is do hope you enjoyed this video unread is do hope you enjoyed this video unread is a fantastic Nas software to do a whole a fantastic Nas software to do a whole a fantastic Nas software to do a whole bunch of different things that is by far bunch of different things that is by far bunch of different things that is by far the most complete and easiest thing that the most complete and easiest thing that the most complete and easiest thing that I've used so far in feature Rich I've I've used so far in feature Rich I've I've used so far in feature Rich I've used uh open media Vault true Nas core used uh open media Vault true Nas core used uh open media Vault true Nas core and scale proxmox or some things and and scale proxmox or some things and and scale proxmox or some things and overall unraid seems to be the move when overall unraid seems to be the move when overall unraid seems to be the move when it comes to what I like to use I do it comes to what I like to use I do it comes to what I like to use I do recommend this channel right here if you recommend this channel right here if you recommend this channel right here if you are interested in learning more space are interested in learning more space are interested in learning more space invader one is way more intelligent than invader one is way more intelligent than invader one is way more intelligent than me when it comes to unread and has a ton me when it comes to unread and has a ton me when it comes to unread and has a ton of different tutorials and I end up of different tutorials and I end up of different tutorials and I end up watching his tutorials quite a bit when watching his tutorials quite a bit when watching his tutorials quite a bit when it comes to trying to figure out things it comes to trying to figure out things it comes to trying to figure out things that I need to do and with all that I do that I need to do and with all that I do that I need to do and with all that I do hope you have an absolutely wonderful hope you have an absolutely wonderful hope you have an absolutely wonderful day and good bye
