How reproducible:

Always

Steps to Reproduce:

1.Create and start a volume.

[root@dhcp43-116 gluster_pkgs]# gluster volume create newvolume replica 2 10.70.43.116:/bricks/brick0/b0 10.70.43.88:/bricks/brick0/b0 10.70.42.47:/bricks/brick0/b0 10.70.42.237:/bricks/brick0/b0 
volume create: newvolume: success: please start the volume to access data

[root@dhcp43-116 gluster_pkgs]# gluster volume start newvolume
volume start: newvolume: success

2. Enable ganesha on the volume

[root@dhcp43-116 gluster_pkgs]# gluster vol set newvolume ganesha.enable on
volume set: success

3. Try to unexport the volume and observe that unexport always fails with "Dynamic export addition/deletion failed"

[root@dhcp43-116 gluster_pkgs]# gluster vol set newvolume ganesha.enable off
volume set: failed: Dynamic export addition/deletion failed. Please see log file for details

Following message is observed in ganesha.log

23/08/2016 20:49:28 : epoch 57bc690e : dhcp43-116.lab.eng.blr.redhat.com : ganesha.nfsd-8143[dbus_heartbeat] dbus_message_entrypoint :DBUS :MAJ :Method (RemoveExport) on (org.ganesha.nfsd.exportmgr) failed: name = (org.freedesktop.DBus.Error.InvalidArgs), message = (Cannot remove export with id 0)


Actual results:

Unexporting ganesha volume fails with "Dynamic export addition/deletion failed"

Expected results:

There should not be any errors and unexport should be successful.
