This suggests that there are concurrent gluster cli operations been
performed on the same volume. Are you monitoring the cluster through nagios
or you have a script on all the nodes which checks for volume's health in a
period of interval? Please note glusterd will process one cli operation on
a volume at one time, the rest all transactions on the same volume will be
failed.
