I would like to import an existing Software-Raid1 to OMV4.
I installed the disks into the machine.
mdadm is configured correctly, /proc/mdstat shows the expected output
I can mount the array manually from the command line.
So the array itself seems to work ok.
In the GUI I can see the physical disks
I can see the array as clean with the correct capacity under Raid Management.
But I don't see the filesystem (ext4) under file systems
How to make that array usable in OMV4?
