This is a bit long-winded, but I wanted to share some info
Regarding my earlier message about a possible race condition with mdadm,
I have been doing all sorts of poking around with the boot process.
Thanks to a tip from Steven Yellin at Stanford, I found where to add a
delay in the rc.sy
Well, I tried adding a 5-second sleep to the mdadm startup in the
sysinit script, and 10 seconds in the mdmonitor script, but it made no
difference. I still got the spare partitions not included in two of the
arrays. What I find curious is that it's always the hot spares, never
the active com

Yes, use the ATI driver in Elrepo; it works for me with SL6 x86_64.
Another note with regards to LVM: with our infrastructure we did some basic
IOZone and bonnie++ tests and discovered that use of LVM causes up to a 10%
performance hit for I/O operations in relation to using a native partition
table. This convenience did not seem to be worth the hit in performa

Maybe I missed it, but I didn't see any response to your request
