December 22, 20223 yr Alright panic moment. Upgraded from 6.9.x to 6.11.5 and after it came back up, six drives are now showing "Unmountable: Wrong or no filesystem" despite working fine before. Log attached. I have one disk that has a bunch of CRC errors, but I think it's the SATA controller, not the drive. Otherwise this rig has been running stable for over a year and from upgrading it just... fell over. 5 of these disks are btrfs and 1 is xfs. But there's 1 btrfs that is working. bakugo-diagnostics-20221222-1145.zip
December 22, 20223 yr Community Expert Something weird is going on there, please post the output of: btrfs fi show Also check filesystem on disk19.
December 22, 20223 yr Author Here is the output: https://i.imgur.com/Erf3UIM.png disk19 has errored out to missing again so it's probably dead. I have a replacement OTW but it had already been "missing" for a while, so shouldn't be the cause of these issues. EDIT: Also worth noting the data rebuild operation is now at 330%?! lol Edited December 22, 20223 yr by EposVox
December 22, 20223 yr Author Just a thought: All but the "dead" one are super small drives (500GB and 1TB) - should I just mount them in maintenance mode, offload their contents and then format?
December 23, 20223 yr Community Expert Disks 1, 4, 10, 15, 22 and one cache device are all from the same btrfs pool, if there's data there you want to recover you can mount them together in a pool, but you'll need to do a new config, I can post detailed instructions if you want to do that.
December 23, 20223 yr Author I don't believe there's anything necessary on them. However after a reboot, both cache devices are now giving the same method whereas only one was before. If I don't want any data from those drives, what's the best route to remove them from my pool without starting over/losing everything? If I just choose No Device before starting up the array, it tells me too many missing/wrong disks. Would I have to go one at a time? Data rebuild also went a full 24 hours and over like 1200% before I had to reboot it anyway. Not sure what that's about.

Tools -> New config Then unassign all those devices, you can re-arrange the remaining ones if you want, than start array to begin a parity sync.
