Hello All,
I am a unraid and Linux novice, I have been using unraid for about a year now as a NAS/Plex server. Recently I've been getting some SMART errors on my cache drive. While attempting to swap in a new drive I seem to have inadvertently locked my existing cache drive (with data still on it) in an "Unmountable: Unsupported or no file system" state (Haven't re-formatted or anything). I had already set the shares to cache (after disabling docker, don't use VM's) and invoked mover. ~40 gb of data was moved to my array, but ~400gb of data still showed on my cache drive. I am 99% sure I had manually set my plex server to save the metadata onto the cache drive, and this is the data in question. I was struggling to get this copied off, and decided (in hindsight poorly) to start the array with my new SSD as the cache drive, leaving the old cache drive as an "unassigned device". Basically as expected Plex was broken. When I took the array off line and swapped the cache back to the old drive. It showed as "Unmountable: Unsupported or no file system". I attempted to copy the data onto my windows PC directly (shut server down, connected a SATA->USB cable directly to the SSD) but windows didn't seem to recognize the drive as-is. I'm sure I made a bunch of newbie mistake and would be eternally grateful if some of you folks could help me out of this pickle.
Log attached (I think?)
