But am I heading for problems here? Is there going to be a big
performance hit
with four raid5 arrays on the same machine? Am I likely to have dataloss

use LVM, that way you can resize the volumns

So now, my options are between the following:
1. Single 12TB /dev/md0, partitioned into four 3TB partitions. But how do
I do this? fdisk
