As discussed, the issue wasn't reproduced on setup with 4node samba and 4 clients when ctdb was added. The issue originally was reported with samba cluster but no ctdb which is not a valid setup. Hence deferring it from 3.3.

But would like to retain the BZ and see if there is any other bug that is being exposed only in non CTDB setup as the same was working earlier.

Hi Karan,

I looked over the from comment #9. It's weird that I am not seeing any 'Permission denied' or related errors in any of the logs(samba/glusterfs-client/brick logs). Since you mentioned it as 100% reproducible, can you please make the following changes to /etc/samba/smb.conf and re-run the tests in hope of getting some useful logs.

* Change 'max log size = 50' --> 'max log size = 0'
* Add 'log level = 7'
* And in [glusterfs-<VOLNAME>] section change 'glusterfs:loglevel = 7' --> 'glusterfs:loglevel = 8'

Additionally, you can also increase the brick log level to DEBUG.
