Note: I ran SpinRite (about a 24 hr test) on both 8tb drives before starting this process. No errors.

Hello. Gotta go to work. I will return in about 10 hrs. Diag posted. Thank you tower-diagnostics-20260928-0802.zip

Hello I followed your steps. on main click on the first device for that pool and then "remove pool" back on main, create a new pool with the same name and 2 slots assign the pool devices (sdf and sde), leave the filesystem set to auto start the array to import the pool Looking good. stop array remove 2TB Add 8tb start array ZFS pool in degraded state. ------------------- root@Tower:~# zpool status pool: zfs state: DEGRADED status: One or more devices is currently being resilvered.

Hi I am in trouble and need help. My array disks, I believe, are fine and I did not change them. I am trying to upgrade my two 2TB disk ZFS mirror pool to two 8tb disks. I replaced one 2tb disk with an 8tb (part s/n ZM25G) disk started the array and the resilver process completed yesterday. Today, I tried to replace the second 2tb disk with an 8tb disk. I got "wrong pool state" from unraid. I have changed pool membership a few times. I have upset Unraid because my 'start array' button is now greyed out. Goal --> keep data and have a two 8TB disk ZFS mirror pool. Diag file attached. How do I get there? Thank you tower-diagnostics-20260926-1132.zip

What I did: Remove data and shares from both pools. (don't have to deal with changes to the 'shares' tab later) Stop array Delete 'cache' pool with 480 GB drive. Rename pool with 750 GB drives to 'cache' Thank you

Hello, I was experimenting with some new disks on my Unraid server and now I have a cfg I need some help to get rid of. The end goal is to use the two 750 GB disks as a ZFS cache mirror. Currently only test data on both 750 GB disks so they can be erased. The 480 GB disk is empty (screenshot) and is going into retirement. I tried unsuccessfully to delete the "Cache-zfs" pool. I need some guidance. How do I move to a config using a 750 GB ZFS mirror as my Cache? Thank you

Perfect. Thank you.

I hope I did not feed you poor information. You said "named files1, but all files for that user share are not necessarily on the ZFS pool." files1 is an exclusive share on a ZFS pool. Therefore (I believe) all of the files are on the ZFS pool. Correct? You said "Similar for /mnt/user/files4, a user share named files4 but all files for that user share are not necessarily on the array." This share was created using the GUI 'shares' tab, so I think all files will be on the array. (excluding a possible short stop on a cache). Correct? Thank you

Hello, I want to use the Unraid CLI (click the icon top right and login as root) to backup / copy some files. Most of the source files are located on a ZFS pool and I would like to make a copy using rsync (now and then) to the Unraid array. ZFS pool source: /mnt/user/files1 Backup target: /mnt/user/Backup/files2 Unraid Array source: /mnt/user/files4 Backup target: /mnt/user/Backup/files5 Is there any reason this is a bad idea? I just want a simple method to create another copy of some files. Next stage is offsite. Thank you

Advice taken. Files have been deleted. Thank you for your help.

Hello, I am trying to move my appdata and system shares to a different (new & zfs) cache pool. I have watched the SpaceInvader video here: https://www.youtube.com/watch?v=vXF8au5o9Tw&t=308s System share will not move completely. I have stopped all of my dockers and virtual machines. I have gone to Unraid settings and stopped the docker and VM service. This should release the files and make them available to be moved. System share will not move. docker and libvirt seem to be causing the issue. I did read JorgeB said "Mover won't move files that already exist on destination." There appears to be old copies of libvirt.img and docker.img on disk2. The time stamp of the IMG files on the cache drive is updated when I start the two services. The goal is to move system share to the array, then move system share to a different pool device. Can I delete libvirt.img and docker.img on disk2 without data loss? Thank you

Hi I am running Plex in a VM on a Ubuntu server and my media is on my Unraid server. (I don't want a Plex docker) I am not getting 'stale file handle' errors sometimes. Is the recommended fix still this? "Settings => Global Share Settings => Tunable (support Hard Links)" to NO https://forums.unraid.net/bug-reports/stable-releases/nfs-is-about-useless-in-unraid-680-r822/?tab=comments#comment-8059 No other downsides to be concerned with? Thank you
