Hi, I decided I would hammer my GlusterFS NFS mounts with: # watch -n 0 dd if=/dev/zero of=ddfile bs=8k count=2000000 I stopped the writes long ago, yet my gluster server is still going along.

Why are there big reads when I was only doing a write test? Why is the ethernet still busy? Looks like I'm back to trying DRBD.
