When ever I try to make a filesystem on OMV I get this message:
Code
mkfs.ext4 /dev/sdb1
/dev/sdb1 is apparently in use by the system; will not make a filesystem here!
I am able to fdisk on sdb and delete and make partitions. I have tested multiple types of drives. The webgui just tries to do it and obviously does not succeed. There are no RAID configurations set up.
