[Gluster-users] WRITE => -1 (Input/output error)

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
'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
 Run in debug mode. This option sets --no-daemon, --log-level to DEBUG,
and --log-file to console.
