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.
For more info, see: 'glusterfs --help' or 'man glusterfs'.
The mount.glusterfs handler may be reviewed via: 'less -S $(which mount.glusterfs)'
[1] Run in debug mode. This option sets --no-daemon, --log-level to DEBUG, and --log-file to console.
'glusterfs --volfile-server=$onevolumeserver --log-file=$logfile --log-level=$level --volfile-id=$volname $mountpoint`
I like to use '--no-daemon', or the '--debug'[1]. For $level, start with DEBUG, then try TRACE. TRACE is _very_ verbose.

None that I am aware of, would I be looking in Gluster logs to see EIO?
I had a look at the source code for fuse_writev_cbk to see if I could give me some hints as to where the issue is however no joy.
Would there be somewhere that would tell me what operation is failing what file etc? Maybe I can turn up logging level.
