March 22, 20224 yr I have tried upgrading from RC2 to RC3 and now RC4 with a dual cache drive pool. After rebooting and starting the array I get Unmountable: Invalid Pool config. If I restore back to RC2 everything starts and works normally. Any ideas or suggestions? diagnostics-20220322-1100.zip
March 22, 20224 yr Community Expert Solution Problem is caused by only having one array disk with btrfs, this makes parity appear to have a valid btrfs filesystem and generates an error during device scan: Mar 22 10:59:47 RizzoUnraid emhttpd: /mnt/cache_ssd ERROR: cannot scan /dev/sdl1: Input/output error Though strange that it doesn't happen with rc2, in any case best way forward to avoid this now and in the future is to either have more btrfs arrays disks on convert disk10 to xfs like the rest.

May 20, 20224 yr What if I have 3 cache drives as a pool under btrfs and I'm getting the "unmountable: Invalid pool config"?
May 20, 20224 yr Community Expert 14 minutes ago, minhquan07 said: sorry this is the one with the 3 cache drives This is a known issue when there's only one assigned btrfs array drive, it creates an invalid btrfs filesystem on parity that confuses the pool, workaround is to convert that disk to xfs like the other ones, add more btrfs array devices or if you want one but only one btrfs array device use encrypted btrfs.
May 20, 20224 yr When I go to the cache -> file system type: -> options are only auto, btrfs, btrfs - encripted is there another way of changing the file system?
May 20, 20224 yr Community Expert 9 minutes ago, minhquan07 said: When I go to the cache Problem is not with cache, it's the single btrfs array disk, disk5, that's the one that should be converted to XFS or encrypted btrfs, note that both require formatting the disk, i.e., all data there will be lost.
