March 5, 20215 yr I had 2 cache drive with raid 1 and it started to have this problem where it would just stop being able to write to after a few mins of restarting. So, I though since it’s raid 1 I’ll just put one into undersigned devices and copy the data over to the other after formatting. But I get this error when trying to mount the drive to unassigned devices. Plz I need help Mar 4 09:28:38 Tower unassigned.devices: Adding disk '/dev/sdf1'... Mar 4 09:28:38 Tower unassigned.devices: Mount drive command: /sbin/mount -t btrfs -o rw,auto,async,noatime,nodiratime,discard '/dev/sdf1' '/mnt/disks/Samsung_SSD_860_EVO_1TB_S5B3NY' Mar 4 09:28:38 Tower kernel: BTRFS info (device sdf1): turning on sync discard Mar 4 09:28:38 Tower kernel: BTRFS info (device sdf1): disk space caching is enabled Mar 4 09:28:38 Tower kernel: BTRFS info (device sdf1): has skinny extents Mar 4 09:28:38 Tower kernel: BTRFS error (device sdf1): devid 1 uuid d721e849-7541-47b3-8eb4-065e7e84f756 is missing Mar 4 09:28:38 Tower kernel: BTRFS error (device sdf1): failed to read the system array: -2 Mar 4 09:28:38 Tower kernel: BTRFS error (device sdf1): open_ctree failed Mar 4 09:28:38 Tower unassigned.devices: Mount of '/dev/sdf1' failed.
