Mount GlusterFS volume as non-root user

Changed in version 3.7.3: GlusterFS versions prior to version 3.7.3 requires the following additional steps to allow non-root users to mount the volume over libgfapi. Following these steps is not required for recent versions i.e >= 3.7.3

One can follow the following steps to allow a non-root user to virtual mount a GlusterFS volume over libgfapi. This requires a configuration change which enables GlusterFS server to accept client connections from non-priveledged ports.

# gluster volume set <volname> server.allow-insecure on
# gluster volume stop <volname>
# gluster volume start <volname>

Edit /etc/glusterfs/glusterd.vol or /usr/local/etc/glusterfs/glusterd.vol and set:

option rpc-auth-allow-insecure on

Restart glusterd service:

# service glusterd restart

Further, use chown and/or chmod commands to change permissions on mount point or required directories to allow non-root access to appropriate users.

If you do not provide a custom location for log file, you might see an error similar to the following during mount.

LibgfapiException: glfs_set_logging(None, 7) failed: Permission denied

In such case, provide a log file path that has appropriate write permissions or change permission of default log location i.e /var/log/glusterfs or /usr/local/var/log/glusterfs accordingly.
