Description Shashank Raj 2016-06-18 13:12:26 UTC

Description of problem:

nfs-ganesha disable doesn't delete nfs-ganesha folder from /var/run/gluster/shared_storage

Version-Release number of selected component (if applicable):

nfs-ganesha-2.3.1-8

How reproducible:

Always

Steps to Reproduce:

1. On a already running nfs-ganesha cluster, disable nfs-ganesha using below command:

gluster nfs-ganesha disable

2. Observe that the nfs-ganesha folder, which is being created under /var/run/gluster/shared_storage during nfs-ganesha enable, doesn't get deleted from the path


Actual results:

nfs-ganesha disable doesn't delete nfs-ganesha folder from /var/run/gluster/shared_storage

Expected results:

the nfs-ganesha folder should get deleted from /var/run/gluster/shared_storage once we disable nfs-ganesha on the cluster.

Comment 3 Jiffin 2016-09-16 10:10:37 UTC

Patch http://review.gluster.org/#/c/14833/ got merged in upstream 3.8

Comment 4 Jiffin 2016-09-16 10:46:22 UTC

This change is already part of rebase

Comment 7 Shashank Raj 2016-10-06 11:54:32 UTC

With current design in 3.2, once we disable nfs-ganesha on the cluster, the nfs-ganesha folder under /var/run/gluster/shared_storage should not get deleted because we are recommending to manually create it once we setup ganesha for the first time.

So after tearing down ganesha cluster, following is the behavior:

symlink to ganesha.conf under shared storage will get removed

[root@dhcp43-110 ~]# cd /etc/ganesha/
[root@dhcp43-110 ganesha]# ls
ganesha.conf  ganesha-ha.conf  ganesha-ha.conf.sample

and the nfs-ganesha folder under shared storage will still be there but entries other than ganesha.conf and ganesha-ha.conf will get removed:

[root@dhcp43-110 ganesha]# cd /var/run/gluster/shared_storage/
[root@dhcp43-110 shared_storage]# ls
nfs-ganesha
[root@dhcp43-110 shared_storage]# cd nfs-ganesha/
[root@dhcp43-110 nfs-ganesha]# ls
ganesha.conf  ganesha-ha.conf

Jiffin,

Please confirm that the above behavior is as expected. Based on that i will mark this bug as Verified.

Comment 8 Jiffin 2016-10-09 03:45:21 UTC

Correct Shashank. This is current behavior. Previously directory "nfs-ganesha" in shared storage was used only for storing state of different nfs client. Now it is stored to store configuration file like ganesha.conf and ganesha-ha.conf. So all the entries expect these two should be deleted from "nfs-ganesha" folder in shared storage.

Comment 9 Shashank Raj 2016-10-10 10:06:25 UTC

Based on comment 7 and 8, marking this bug as Verified.
