From Unraid "Fix Common Problems":
cache (WDC_WD10EACS-00ZJB0_WD-WCASJ0683266) has file system errors (No file system (32))
If the disk if XFS / REISERFS, stop the array, restart the Array in Maintenance mode, and run the file system checks. If the disk is BTRFS, then just run the file system checksIf the disk is listed as being unmountable, and it has data on it, whatever you do do not hit the format button. Seek assistance HERE
My Main tab is listing my Cache drive as "unmountable"
What are my next steps?
