Thank you so much, it worked.

I would really appreciate it if you could post the steps, please.

I have a zfs raidz1 pool with 3x6TB drives. I shut the server down. I removed one drive that had bad sectors. Right before I clicked Start Array, I got to the three boxes in the UI that showed two drives and an empty space, and I added the new drive there. I clicked Start Array. After the array started, I saw a message that the array was in a degraded state and it started rebuilding. After the rebuilding was completed, instead of working normally, it showed the message: status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using 'zpool replace'. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-4J. I tried to run the following commands: root@Olympus:~# zpool status -v nerv pool: nerv state: DEGRADED status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using 'zpool replace'. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-4J scan: resilvered 1.21T in 02:05:50 with 0 errors on Wed Jul 8 15:57:37 2026 config: NAME STATE READ WRITE CKSUM nerv DEGRADED 0 0 0 raidz1-0 DEGRADED 0 0 0 22961051357565640 FAULTED 0 0 0 was /dev/sdd1 sdd1 ONLINE 0 0 0 sdf ONLINE 0 0 0 errors: No known data errors root@Olympus:~# zpool detach nerv 22961051357565640 cannot detach 22961051357565640: only applicable to mirror and replacing vdevs For more information, look at the images and the diagnostics. What caused this problem? And how can I fix it without losing my data? Everything else seems to be working normally. The same thing happened the last time I tried to replace a drive. Back then, I thought it could be a weird software glitch, so I restarted the server. When I tried to start the pools, I got an error that said "nerv is in an invalid pool configuration". I tried to delete that pool and make it again, but every time I added the three drives, the same error appeared. That time I had a spare drive to dump all my data and format, but now I don't have this luxury. olympus-diagnostics-20260708-1646.zip

Is there to back up my photos/videos in unraid but after the backup has been completed the photos/videos on my phone are replaced with low-resolution equivalents? In my gallery app (android 14, samsung) I have the ability to sync my gallery with an onedrive account and I believe it will do the same. If the above isn't possible, is it possible to "host" my own onedrive with login credentials to add to the gallery? Do you have any suggestions?
