Description shilpa 2013-10-11 11:11:17 UTC 
Description of problem:
When I run mount command with "-o backupvolfile-server" option, it does not reflect.Could not see it in "ps aux" command.


Version-Release number of selected component (if applicable):
glusterfs-3.4.0.34rhs-1.el6_4.x86_64
Client RHEL 6.4 

How reproducible:
Always

Steps to Reproduce:
1.Create distribute replicate volume and apply all the necessary volume options.
2.Mount the volume on a client RHEL6.4 with the command:
#mount -t glusterfs -o backupvolfile-server=10.70.37.77 10.70.37.168:vol /mnt/gluster
3.Check the output of "ps aux | grep glusterfs" to see if the option is applied

Actual results:
# ps aux | grep glusterfs
root     13189  2.0  0.4 336824 68028 ?        Ssl  15:30   0:00 /usr/sbin/glusterfs --volfile-id=cinder-vol --volfile-server=10.70.37.168 /mnt/gluster

Initially tested this on RHS-RHOS setup.. But it is also reproducible on a client without RHOS setup.

Expected results:

Backupvolfile-server should be applied successfully after the mount command

Saw the steps done for opening this bug:

> 3.Check the output of "ps aux | grep glusterfs" to see if the option is applied

This is not a valid step as of now in RHS2.1 (or RHS2.0) as the backup-volfile server option is handled at mount.glusterfs script.

https://github.com/gluster/glusterfs/blob/release-3.4/xlators/mount/fuse/utils/mount.glusterfs.in (line 224 onwards).


In future (when we rebase to glusterfs version 3.5.0 or higher), this will be a valid step.

https://github.com/gluster/glusterfs/blob/release-3.5/xlators/mount/fuse/utils/mount.glusterfs.in


Hope this is good enough information to close the bug.
