I debug fuse mounts by running glusterfs binary directly with the below command. I find it works best to incorporate this command into a test script.
'glusterfs --volfile-server=$onevolumeserver --log-file=$logfile --log-level=$level --volfile-id=$volname $mountpoint` I like to use '--no-daemon', or the '--debug'. For $level, start with DEBUG, then try TRACE. TRACE is _very_ verbose. For more info, see: 'glusterfs --help' or 'man glusterfs'. The mount.glusterfs handler may be reviewed via: 'less -S $(which mount.glusterfs)'  Run in debug mode. This option sets --no-daemon, --log-level to DEBUG, and --log-file to console.
