Thank you for looking. I ended up just copying the files from the cache drive to the array and back again. This prompted me to discover that I did not have cache configured the way I thought it was in the first place, as some files were intended for cache but were actually on the array... I think I'm in a much better spot now, independent of how I got there.

Edited the original post with the diagnostics. Thank you!

Hello all. I was installing a new disk in my "main" array and in the process must have unseated one of the cables on my cache pool drives. I am an idiot and tried to "fix" the cache pool by removing the disconnected drive from the pool (in the Unraid UI) -- I deleted and recreated the cache pool several times (I thought this would be a temporary fix and that the cache would work with only one drive, but it didn't). I re-seated all the cables and the drives are back to "normal," but Unraid won't mount the cache pool in the UI. I used Google and was able to mount the cache drive via CLI and am currently copying the files off to my main array, but someone suggested on Reddit that I should check here to see if there is a way to "force" Unraid to mount the pool. I was/am running two SSDs on a BTRFS RAID1 configuration. I thought I had Unraid configured to sync the files to my main array, but I guess not. I'm not really worried about data loss at this point, but if there's a better way than just formatting the cache pool and copying the files back down, I'd appreciate the help / suggestions. Thanks in advance. nas-diagnostics-20260731-1355.zip
