[Gluster-users] Gluster peers disconnecting

I'm running Gluster 3.3 on a four host setup. (Two bricks per host.)
I'm attempting to use this as an rsnapshot backup system. Periodically,
the rsync's seem to fail, and I think this is due to underlying gluster
failures. I notice this in /var/log/messages:
# Jul 19 23:47:15 annex1 GlusterFS: [2012-07-19 23:47:15.424909]
_timer_expired] 0-gbackups-client-2: server 172.16.1.83:24009 has not
responded in the last 42 seconds, disconnecting.
I notice that df shows a smaller than normal volume size, which returns
to normal after a remount.
$ df -h
55T 1.6T 54T 3% /mnt/gbackups
$ umount /mnt/gbackups
$ df -h
73T 1.9T 71T 3% /mnt/gbackups
One rsnapshot error that I get is:
# [19/Jul/2012:23:50:01] /usr/bin/rsnapshot
-c /etc/rsnapshot/rsnapshot-sftp/rsnapshot.conf sync: ERROR: /bin/cp
-al /mnt/gbackups/rsnapshot/sftp/daily.0 /mnt/gbackups/rsnapshot/sftp/.sync failed (result 256, exit status 1). Perhaps your cp does not support -al options?
I've manually tested the cp -al and it's working fine. It's most likely
due to a node that's dropping out temporarily.
Doing a gluster peer status shows all nodes "connected".
Any ideas what is causing this please?
Thanks in advance,
