It looks like the write took too long - as a first step, you might want to
up the disk heartbeat timeouts on those systems. Run:

$ /etc/init.d/o2cb configure

on each node to do that. That won't hide any hardware problems, but if the
problem is just a latency to get the write to disk, it'd help tune it away.
