Hi, I set up OMV in a VM, with the following drives,
8GB, 12GB, 15GB, 10GB, 8GB, 10GB, 11GB, 15GB, 20GB, 8GB, 8GB
This totals 110GB. But when I set up raid 5, I got 71.93GB, and with raid 6 I got 63.94GB.
I can conclude from that it doesn't play nicely with drives of differing sizes, am I correct? Is it only using 8GB from each drive?
I thought a file system such as EXT4 was for a single drive? How can I build a raid array and then format it EXT4? What technology is the raid array being built with?
If I can use EXT4 across drives then what advantage would XFS give?
