7.1.4 Started having trouble 1 week ago. I lost a drive in the cache pool. I thought it was in raid 1 btrfs, but either way I couldn't recover the appdata. Added a new 1TB cache drive & started losing the web gui every night. I tried running in safe mode with no plugins and that did not help. Cleaned the server today and disk 2 showed a red x and as having the wrong file system but no smart errors. I removed disk 2 from array, started array, stopped array and added disk back to start array. Rebuild began, but disk still shows as unmountable: wrong or no file system. Most recent diagnostics attached.
