Hy guys,
after an reinstall from my NAS to OMV3, I can't bind in/mount my old Raid5.
What have I done before, after the reinstall my Physical Disks were shown but not in the Raid
Management. So I start with the commands from this Post to find the issue. The result was that the superblock on devices has an issue.
This I solve with the below commads for my devices sda,sdb & sdd
now I see my Raid5 in the Raid management, but I can't mount it in the file system. the mount button is grey
So how must i proceed?
Below the current status
