I thought I should report here as well.
I've installed Centos 5.4 x64 and all going well so far.
No corruptions at all.
My setup is as before
sdb (hard raid5)
|
|------> md0 (soft raid0)----> LVM ----> ext4
|
sdc (hard raid5)
The only strange thing I've noticed is that pvcreate
is messing with the gpt label on md0. Don't know of that
is normal.
