I'm trying to set a parameter on a volume, but unable to due to the

You could grep for "accepted client from" in /var/log/glusterfs/bricks
to get an idea of the versions of connected clients.
I had sent a patch [1] to improve the error message to indicate which
client is the culprit here. This is not the first time I've heard an
user complaining about it, so will try to get it in the release stream.

Anyone up for review?

This is definitely better than the state we have now. I looked at the patch. Looks fine. If you could resend the patch with BUG-id lets take it in.

What would be even better is if we can enhance "gluster volume status clients" which prints the clients connected at the moment to also print the min,max op-versions so that the users can get the versions of all clients in one command.
