OK. In a system with four drives, what is the best configuration?
2 x RAID1

A)
mirror disks 0 & 1
mirror disks 2 & 3

for two RAID 1 container
ok

B)
stripe disks 0 & 1
stripe disks 2 & 3
mirror container 1 with container 2
I wouldn't stripe, just mirror

What would be an indication of disk bottleneck?
with 1 second sampling:

cpu averaging 95+ % idle

and high disk i/o to one or both RAID pairs every second
