Yep, we're on ext2. Our current crop of production servers were
installed over a year ago and are based on Red Hat 6.2. The
kernels have been updated somewhat and have SMP and large
file system support but are still 2.2 based. At the time these were
setup journaled filesystems on Linux were still iffy. I've not seen
much of a need for 'em in a datacenter machine that's rarely
rebooted and isn't likely to lose power.
I do have several servers in the office running Suse 7.2 and a
journaled filesystem (can't remember which) and they've been
no problem. Not much load on them, though. I'm going to be
upgrading some servers here soon to a more modern kernel
and will probably use Suse instead of Red Hat.
Most of these servers have the max RAM they hold--2 GB for the
Dell 2450. Memory is so cheap at the moment--even the
registered ECC stuff--there's no reason not to fill 'em up.
These servers have been very reliable. Most have uptimes of
over 100 days (extra RAM installed the cause of the most recent
reboot) and several are over 400 days. I haven't been in too
much of a hurry to make any changes since they've been so
stable.
