November 22, 2025Nov 22 I'm pretty sure my data is gone, but I'd appreciate a second opinion before nuking my zfs pool. The pool is 3 sets or 3 drives.My issue started with a drive throwing errors. They are used drives, so I wasn't too surprised. Then to seal the deal I had a power outage during a resilver (battery backup didn't last long enough for a clean shutdown). After that I've tried a whole bunch of random things to get it back, which I'm sure were more nails in the coffin.I'm curious if I could have help verifying that the data is in fact gone (my own fault if it is).If it is gone can I verify which drive failed.And finally is there any way to bring back my folder structure? I'm not sure if it's kept track of anywhere other than the zfs pool.Thank you!
November 23, 2025Nov 23 Community Expert This RAIDZ VDEV is missing two drives, so unless you can make one of them come online, or one of them can still be mostly cloned with ddrescue, the pool is likely gone.
November 23, 2025Nov 23 Author Thank you for taking your time to look at it.The sdh1 drive is physically present, and I can pull smart data from it. It does not show a partition as being present though. The last drive on the list is gone though.What would it take to take a look at the drive and see what happened to the partition? As in see if there's something 'simple' that went wrong or it it's all corrupt. tower-smart-20251123-0851.zip

November 24, 2025Nov 24 Author I've attached the one I pulled on saturday. I can run another this evening if it'd be helpful. tower-diagnostics-20251122-1344.zip
November 24, 2025Nov 24 Community Expert Solution All the other pool devices are using the standard layout, so try:sgdisk -o -a 8 -n 1:32K:0 /dev/sdXReplace X with the correct letter, then try zpool import again.

November 25, 2025Nov 25 Community Expert For all pool disks, post the output from:zdb -l /dev/sdx1 | grep txg
November 25, 2025Nov 25 Author I tried sdh a couple different times. I expect sdg to be wrong. Edited November 25, 2025Nov 25 by Vicinity3
November 26, 2025Nov 26 Community Expert I'm afraid it wasn't just the missing parition, so don't think it will be possible to recover the pool.
