My guess is that the RAID has nothing to do with it -- it seems very unlikely.
In any case, if you want top performance out of your raid, you may
want to change things up. You'd get better performance if you didn't
use RAID5. Use RAID1 or RAID10 for your data drives. RAID5 is slower
than these other methods.
Based on the information you've given, I'm assuming a few things:
1) your raid controller supports RAID10
2) you have an even number of drives.
If this is the case, I would recreate the raid as a RAID10 (pair up
your drives and then create a stripe out of the pairs). Then you can
feel free to allocate space to whatever partition struction you need.

G'morning all!
(Using Red Hat Linux Enterprise 4.1)
I have a Dell PowerEdge 2800 with a PERC 4 RAID controller. The RAID
controller has one RAID 1 mirror and one RAID 5 stripe volume created.
We installed most of the OS stuff on the RAID 1 set and the
/usr/local and /var on the RAID 5 set (since the Red Hat MySQL rpm
puts the data directory under /var ).
use LVM to set things up, so you can resize later without taking the
system down.
