Does linux
know anything about NCQ, or is everything abstracted to the
controller?
Good question, not knowing the answer I did a quick google and this
came to the top:
http://linux-ata.org/driver-status.html
another good one,
http://blog.kovyrin.net/2006/08/11/turn-on-ncq-on-ich-linux/
Looks like support wasn't added until 2.6.18 and isn't widely
supported until 2.6.19 and 2.6.20.

Ross,
Thank you for the links. Looks like my controller doesn't
support NCQ
:-(. I have the SIL 3114 based card. Doesn't look like
there are any
cheap alternatives on the PCI bus, but I think I can live with the
performance of this system.
How did it go creating the interleaved LVs?
-Ross
It worked... I think.
I already had the LVM partitions set up, but when I booted up into the
install, and went to the shell, I couldn't see them (although the
installer saw them). I had to do raidstart on all my md devices, and
then scan by doing somethign liek vgscan and lvscan, and then the
devices showed up. So I deleted them and re-added them, per your
instructions, and when I printed out the config, looks like they were
striping. I was then able to install on it. So I don't think the
reboot step is necessary, you just need to precreate the config manually
in the shell first.
Thanks for your help.
Russ
