Description of problem:
Volume is still visible under export list #showmount -e localhost even after
volume is in stopped state.
Export ID of the nodes are different for the same export volume while
performing volume start and stop
Version-Release number of selected component (if applicable):
glusterfs-3.8.4-5.el7rhgs.x86_64
# rpm -qa | grep ganesha
glusterfs-ganesha-3.8.4-5.el7rhgs.x86_64
nfs-ganesha-debuginfo-2.4.1-1.el7rhgs.x86_64
nfs-ganesha-2.4.1-1.el7rhgs.x86_64
nfs-ganesha-gluster-2.4.1-1.el7rhgs.x86_64
How reproducible:
Consistently
Steps to Reproduce:
1.Create and start the volume
gluster volume create volganesha1 replica 2 10.70.47.3:/mnt/data1/b1
10.70.47.159:/mnt/data1/b1 10.70.46.241:/mnt/data1/b1
10.70.46.219:/mnt/data1/b1/ 10.70.47.3:/mnt/data2/b2 10.70.47.159:/mnt/data2/b2
10.70.46.241:/mnt/data2/b2 10.70.46.219:/mnt/data2/b2/ 10.70.47.3:/mnt/data3/b3
10.70.47.159:/mnt/data3/b3 10.70.46.241:/mnt/data3/b3
10.70.46.219:/mnt/data3/b3/
2.gluster vol set volganesha1 ganesha.enable on
3.showmount -e localhost
# showmount -e localhost
Export list for localhost:
/volganesha1 (everyone)
4.Checked export id on all four nodes.Export ID was 2
# dbus-send --type=method_call --print-reply --system --dest=org.ganesha.nfsd
/org/ganesha/nfsd/ExportMgr org.ganesha.nfsd.exportmgr.ShowExports
5.Stop the volume
6.Check Showmount -e localhost
No volume is exported
7.Again start the same volume volganesha1
8.Check showmount -e localhost.
Volume is exported on all the 4 nodes with ID=2
9.Repeat steps from 5 to 8 for 3 times.Each Time when the volume is started
,Export ID is 2.
10.Stop the volume volganesha1
11.Delete the Volume volganesha1
12.Create and start a new Volume volganesha2
13.gluster vol set volganesha2 ganesha.enable on
14.Check showmount -e localhost.Volume is exported with ID=3 on all the four
nodes
15.Stop the volume volganesha2.Check showmount -e localhost.Volume is not
there.
16.Again start the same volume volganesha2.Check showmount -e localhost.Volume
is exported but with DIFFERENT EXPORT IP.
Out of 4 nodes,three nodes have export ID 3 and one node has export ID as 4.
17.Stop the volume volganesha2.
Actual Result:
After stopping the volume,the volume is still visible in showmount -e localhost
on three nodes out of four
Export ID is different on the nodes
Observed the following messages in /var/log/ganesha.log
24/11/2016 15:36:44 : epoch 82a00000 : dhcp46-219.lab.eng.blr.redhat.com :
ganesha.nfsd-18193[dbus_heartbeat] glusterfs_create_export :FSAL :EVENT :Volume
volganesha2 exported at : '/'
24/11/2016 15:37:58 : epoch 82a00000 : dhcp46-219.lab.eng.blr.redhat.com :
ganesha.nfsd-18193[dbus_heartbeat] dbus_message_entrypoint :DBUS :MAJ :Method
(RemoveExport) on (org.ganesha.nfsd.exportmgr) failed: name =
(org.freedesktop.DBus.Error.InvalidArgs), message = (lookup_export failed with
Export id not found)
Expected Result:
After stopping the volume should be unexported successfully.
Export ID should be same in all the 4 nodes when the volume is exported.

ganesha/scripts : avoid incrementing Export Id value for already exported
volumes
Currently a volume will unexport when it stops and reexport it during
volume start
using hook script. And also it increments the value for export id for each
reexport.
Since a hook script is called from every node parallely which may led
inconsistency
for export id value.
