Have you updated to Centos 5.2 yet? And if so, did it improve NFS performance?

Sorry, these computers are in production now so I can't fiddle with them.

Besides, this would be a "long" upgrade -- they are both CentOS 4.x systems.

This raises an interesting question. What do you do in this kind of scenario? How do you upgrade a NAS / SAN with say 5 / 10 TB worth of data?

I haven't done anything that big, but I normally put the OS on a small mirrored pair of swappable drives so an upgrade consists of swapping those drives with a new set pre-installed in a spare chassis. That way you are only down for the time it takes to reboot and if anything goes wrong you can put the old set back. In any case you wouldn't be doing anything to the data partitions in an upgrade.

ok, so in your setup the OS is totally separate from the data itself?

So, I guess I need to rethink my setup. Since I have a 2U chassis, which can only take 6 drives, I guess I should maybe look into running the OS from a USB memory stick or something.
