I'm really new to doing stuff with RAID. I did a fresh install of Ubuntu Server 14.03 and made a RAID0 Array of 3 HDDs. I also set up an LVM on another HDD that's not part of the RAID.
The way I set my partitions up is like this:
LVM root - ext 4 /
LVM swap
sda - EFI boot
ext2 /boot
lvm
RAID - 3 HDDs part of this
When I start up my system, it says Ionly have 1 TB of space. How can I use the RAID array after installation in the terminal. Those drives have a combined total of 4.8TB that I want to use.
When I do mdadm -D /dev/md0
, it brings up this:
/dev/md0:

How do I use the array? Any help would be appreciated. Thanks!
