Hi Gerry,
We were trying to see how glusterfs behaves when "cp -ax"
is started and while cp is happening, kill all the servers.
The log messages which were produced were same as the ones you
have given, So are you sure that glusterfsd processes were not dead
when cp was happening? ( Connection refused would indicate
that glusterfsd is not listening at that port)
We are checking how the log messages can be avoided
when this particular situation is encountered.
Thanks
Krishna

In the log I see this:

repeated tens of thousands of times
The log is growing rapidly. It is now 3G.
Log attached.
About ten minutes later I retried the same command without doing
anything to the servers or clients and it is running:
address@hidden mnt]# cp -ax /usr /mnt/glusterfs0
This behavior is very strange.
