I have a problem with a RAID unit (Adaptec) on a Ubuntu machine. It's a raid5 unit with six 2TB hardrives totalling at about 9-10TB.
The problem is that the reported available space seem to be about 7400GB when checking the properties of the mount.
Adaptec Storage Manager and Disk Utility shows correct sizes. I'm attaching a couple of screenshots. Any idea why this could be?
Greatful for any help, thanks in advance!
