Hi,
I have just moved 7x 2TB Seagate Constellation disks from a broken Thecus N7700PRO NAS. I have tried to wipe the disks (because it has found an existing raid6 field), but got an error on all disks that a disk cannot be wiped (OMV v 0.525), so I could not create a new raid (I have deleted the old one first). So I went to a OMV CLI and ran parted /dev/sdx mklabel gpt on all disks. I could now wipe the disks in OMV GUI and creta a raid. When the raid creation was done (RAID 5, no spare - took about 20-24h) I tried to create a file system on this raid field. I couldn't because I cannot see any raid field in drop down selection. Then I ran parted /dev/md0 mklabel gpt and I could see the drive in the file system creation drop down menu. Is there a way to do this from GUI?
