[Gluster-users] Gluster problems permission denied LOOKUP () /etc/samba/private/msg.sock

Dear all,

I have a two node setup running on Centos and gluster version

One of my nodes died (motherboard issue). Since I had to continue
being up, I modified the quorum to below 50% to make sure I could
still run on one server.

The server runs ovirt and 2 VMs on top of a volume called vmstorage. I
also had a third node in the peer list, but never configured it as an
arbiter, so it just comes up in gluster v status. The server also run
a file server with samba to serve files to windows machines.

The issue is that since starting the server on it's own as the samba
server, I am seeing permission denied errors for the "export" volume
in /var/log/glusterfs/export.log

The errors look like this and repeat over and over:

The gluster volume export is mounted on /export, samba and ctdb are
instructed to use /export/etc/samba/private and /export/lock which is
on the gluster file system for the clustered tdb, etc. However, I keep
getting the log messages that fuse seems to try to access a folder
that does not exist, /etc/samba/private/msg.sock

Why is this, how can I fix it?
