Ok, I: Pre-Req: 1. screenshotted the drives in pool "ocean" Work: 1: CLI - zpool export ocean 2: clicked on "ocean" in UnRaid Web Portal 3: clicked "Remove Pool" 4: typed the name of the pool to confirm 5: added new pool named "ocean" with 24 devices 6: re-assigned all 24 drives 7: verified all 24 drive assignments to screenshot 8: LEFT FILESYSTEM AS AUTO. 9: started array Verified pool with status and list, and can then confirm the CRC checks and all passes, no data lost. THANK YOU!

Also note: ocean is showing in ZFS list, and is online, and I can read data, but Unraid is saying it wants to format it. root@blinky:~# zfs list NAME USED AVAIL REFER MOUNTPOINT lake 98.0G 64.4T 213K /mnt/lake lake/backups 171K 64.4T 171K /mnt/lake/backups lake/downloads 69.4G 64.4T 69.4G /mnt/lake/downloads lake/isos 28.2G 64.4T 28.2G /mnt/lake/isos lake/scans 239M 64.4T 239M /mnt/lake/scans ocean 84.2T 115T 238K /mnt/ocean ocean/data 84.2T 115T 84.2T /mnt/ocean/data pond 18.7G 6.37T 104K /mnt/pond pond/windowsdockers 18.7G 6.37T 18.7G /mnt/pond/windowsdockers puddle 165G 1.64T 20.9G /mnt/puddle puddle/appdata 133G 1.64T 133G /mnt/puddle/appdata puddle/system 10.6G 1.64T 10.6G /mnt/puddle/system root@blinky:~# zpool status ocean pool: ocean state: ONLINE scan: scrub in progress since Wed Nov 20 17:42:11 2024 24.8T / 111T scanned at 13.5G/s, 2.69T / 111T issued at 1.46G/s 0B repaired, 2.44% done, 21:00:12 to go config: NAME STATE READ WRITE CKSUM ocean ONLINE 0 0 0 raidz2-0 ONLINE 0 0 0 sdu1 ONLINE 0 0 0 sdt1 ONLINE 0 0 0 sdx1 ONLINE 0 0 0 sdae1 ONLINE 0 0 0 sdab1 ONLINE 0 0 0 sdaa1 ONLINE 0 0 0 sdac1 ONLINE 0 0 0 sdag1 ONLINE 0 0 0 sdah1 ONLINE 0 0 0 sdz1 ONLINE 0 0 0 sdad1 ONLINE 0 0 0 sdy1 ONLINE 0 0 0 raidz2-1 ONLINE 0 0 0 sdl1 ONLINE 0 0 0 sdm1 ONLINE 0 0 0 sdq1 ONLINE 0 0 0 sdp1 ONLINE 0 0 0 sdar1 ONLINE 0 0 0 sds1 ONLINE 0 0 0 sdw1 ONLINE 0 0 0 sdaq1 ONLINE 0 0 0 sdo1 ONLINE 0 0 0 sdn1 ONLINE 0 0 0 sdv1 ONLINE 0 0 0 sdr1 ONLINE 0 0 0 errors: No known data errors root@blinky:~# blinky-diagnostics-20241120-1818.zip

I recently had a few older disks go bad and ZFS got the better of me, I lost everything and had to recover from glacier, super slow. I recovered and was working on a smaller ZFS pool replacing disks and accidentally left two disks out of the 24 disk main array. I started the array because I needed to resilver the smaller pool and that finished and I realized the two drives were missing in the main array and the pool was unmountable. Now, I stopped the array and went to re-assign the drives to their slots and it wants to format the main array again. I stopped here. How do I re-insert the two drives into the array without losing the entire array again? ocean - 24 x 12 TB SAS Drives. ZFS RaidZ2 2x12drive vdevs. Both drives removed were from the 2nd vdev. OS is 7.0.0 beta.4

An error occurred while testing this indexer Exception (torrentleech): FlareSolverr was unable to process the request, please check FlareSolverr logs. Message: Error: Error solving the challenge. Timeout after 55.0 seconds.: FlareSolverr was unable to process the request, please check FlareSolverr logs. Message: Error: Error solving the challenge. Timeout after 55.0 seconds.

Also, I still have the old disks. It's over 90TB of data on that pool, so restorning will take quite a while, if there is an alternative.

Is it SDAH still the bad one?

Ok, running zpool import ocean stalls - I gave it 24 hours and the command never finishes. zpool status does the same, I gave it 24 hours also. Trying to start the array stalls on mounting disks. blinky-diagnostics-20240912-0951.zip

I have moved SDAH1 to a completely different bay. blinky-diagnostics-20240907-2316.zip

Attached. blinky-diagnostics-20240906-1511.zip

These are the replacements, bad disks were SDAB1 and SDAH

Hello mindhive. I may have messed up, but I know to stop and wait when this happens and research and ask. I had two disks go UNAVAIL in my ZFS pool (Ocean is its name) and purchased two to replace them. since they were unavail, I swapped the drives and started the array. It now is erroring out and wanting me to format the entire pool, which I would love not to do, as restoring that much data from backups will be time consuming. I still have both old disks and the two new disks, but the pool recognizes the two new disks and wont accept the old disks. In my research I found i likely messed up by replacing both, even though they are unavail. I should have done one at a time even though the redundancy is capable of dual loss. Please help me restore my pool and fix this. blinky-diagnostics-20240906-1252.zip

Any ideas on this error?
