Back to my 12 terabyte fileserver, I have decided to split the storage
into four partitions
each of 3TB. This way I can choose between XFS and EXT3 later on.
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 won't handle it. Can GNU Parted handle partitions
this big?
2. Partition the raw disks into four partitions and make
/dev/md0,md1,md2,md3.
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 problems
if my machine crashes?
No. I regularly run a mix of RAID types over the same drives for
performance vs. reliability reasons. And in the past I ran not only
RAID-0 and RAID-5 using various partitions, but the stripe size was
different as well. Survived a number of unscheduled restarts.
