I ran into an unmountable error yesterday after a reboot of my tower. It staied this way even in emulated mode. I was able to fix this with the 'xfs_repair -v -L /dev/md8' as suggested in https://forums.unraid.net/topic/69765-solved-unmountable-no-file-system/. During the trial and error I had set the device to none, so now it wants to rebuild the disk. Unfortunately this goes extremly slow, like less than 1 MB/sec.
I don't see any errors regarding the disc itself. I disabled all dockers and VMs but it stays slow. Memory and cpu load are normal. Rebooting the server doesn't help. I can't find the source of the problem.
