Let's rephrase that. Lets say I just did cookiemonster:/mnt/hde1# mdadm --create /dev/md0 --level=5 --raid-devices=2 /dev/hd[cd]1 --auto mdadm: array /dev/md0 started. Which gives me a RAID5 on 2x200GB (That right now really is a RAID1) And I later on would like to add _another_ 200GB disk to that array and turn it into a 400GB RAID5, can mdadm do that? I see a "grow" switch, but I am abit unclear about the usage. I think I'll be using XFS on that disk, which I understand _Can_ be resized dynamically?
