You may find that mounting the gfs file system with "noatime" option helps

I like the idea of adding in noatime to our gfs share, but with three nodes
running, what would be the proper way to add in "noatime" to fstab, unmount
and remount. Can it be one node at a time? Or, should I unmount the gfs
from all nodes, update and remount?
I can't see why it couldn't be done at run-time.
mount -o noatime,remount /my/gfs/path
on each node in turn. Worst that'll happen is that it'll tell you it won't
do it.
Failing that, changing defaults to defaults,noatime in /etc/fstab will do
it when you reboot the cluster.
