bonnie++ -f
Actually, I'm switching to /home/steve and, as root:
bonnie++ -f -u steve
It's a 4GB machine, so bonnie runs with an 8GB dataset.
I'm installing 4.4 on my desktop box now for testing without raid or
lvm.
I have an FC5 box at the office which does not exhibit the problem with
the 2.6.17 kernel using raid1+lvm2. But the raid is currently running
in degraded mode. I'll be syncing up the other drive tonight and will
test again.
