Hi,
i noticed that one of my VMs had a filesystem error (filesystem in read only mode), so i tried restarting it. It did not come back up and started in an EFI shell, so i went into the VM config and wanted to remove some attached disks... well after saving the VM was gone from Unraid. I was also not able to re-create it, so i went into to console and noticed the whole cache filesystem was in read-only mode.
I completely restarted Unraid, and after i started the array i got the "Unmountable: No file system" error for my cache.
Diagnostics is attached
The two cache drives are
Samsung_SSD_850_PRO_512GB_S2BENWAJ803574W - 512 GB (sdg)
2CT500BX100SSD1_1452F000F1C4 - 500 GB (sdj)
EDIT:
I tried the part about unmountable btrfs filesystems from the FAQ
btrfs restore seems to mostly work, but every file thats bigger than a few Megabytes seems to hang with an
"We seem to be looping a lot on /mnt/disk3/restore2/appdata/pihole/pihole/pihole-FTL.db, do you want to keep going on ? (y/N/a)" error...
