[Gluster-users] backupvolfile-server on 3.5

[Kaushal M]

The mount-options shown in the mount command are the filesystem
options that have been passed to the fuse kernel module from the
glusterfs client process.

The backup-volfile-servers option is not really a filesystem option in
general sense, and is only understood by the glusterfs client process.
So it's not passed to fuse. (I also believe that fuse will reject any
such option if passed, but I am not a 100% sure.) There are several
other such options that don't show up.

If you want to check actually confirm whether the options is being
used or not, you can check the command line used to launch the client
process using ps/pgrep etc. The command line will be similar to
 '/usr/local/sbin/glusterfs --volfile-server=172.17.0.3
--volfile-server=172.17.0.2 --volfile-id=/test /mnt'
