The errors you gave in the log seem to be coming from Filesystem. So
I am pretty sure something is coming from either vfs or gluster
itself. How is the backup job run? what are the uid/gid of the
process? Could you do an strace -ff -f -p <pid-of-backup-job>
-o /path/to/log so that we can find out more about what exactly is
happening. It will create files of the format
/path/to/log.<pid> This should help us figure out more about
what could be happening.<br>

nothing interesting is logged to any of the Gluster logs.
Perhaps this is an issue with Bareos. Just though I would ping
this wonderful group for any wisdom. Thanks for taking the
time to help. If I discover the issue I will post back here.<br>

What do you see in the logs of glusterfs mount and
bricks? Do you think it is possible for you to attach
those logs to this thread so that we can see what could be
going on?<br>
