June 6, 201511 yr Running 6.0-beta12 and my cache now shows as unformated. I can still see the files when I browse vie the GUI. I ran reiserfsck --check /dev/sdc1 and was told reiserfs_open: the reiserfs superblock cannot be found on /dev/sdc1. Failed to open the filesystem. If the partition table has not been changed, and the partition is valid and it really contains a reiserfs partition, then the superblock is corrupted and you need to run this utility with --rebuild-sb. I know that with --rebuild-sb answers need to be perfect, so I'm looking for some help to get this cache back up. Thanks!
June 6, 201511 yr Community Expert Are you sure the cache drive is formatted as reiserfs? If it is xfs or btrfs then the error message would be expected because you are then not using the correct utility to check the drive.
June 6, 201511 yr Community Expert If one of the drives from your parity-protected array is not working, unRAID will simulate it by calculating its data from parity and all the other array drives. But it is not possible for unRAID to simulate your cache disk, so I am very confused when you say it is unformatted but you can still see its files. *EDIT* Maybe some screenshots or something to demonstrate why you think it is unformatted but you can still see its files.
June 6, 201511 yr Author OK, this is weird I went to take a screen shot of it showing as unformated, but after stopping the array (was in maintenance mode) then starting, the cache is now formatted as btrfs and everything is back to normal... might have been an issue with my Plex Docker
