[Gluster-users] backupvolfile-server on 3.5

[Simon Barrett]

Excellent. That explains it all and I do see multiple --volfile-server's on the ps output.

root     17164     1  0 07:44 ?        00:00:00 /usr/sbin/glusterfs --volfile-server=10.31.8.181 --volfile-server=10.31.8.186 --volfile-id=/ov1data1 /mnt

Many thanks,

Simon

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'
