Description of problem:

RHGS 3.3

How reproducible:


Customer Environment

Steps to Reproduce:
1. create empty files using touch
2. writing data to any file on a gluster volume served by samba, the relevant bricks (on which the write is attempted) will crash

The gluster volume on the same cluster that is served by nfs-ganesha appears fine.

A related patch has been posted upstream by Csaba, I suggest to have a look at it. I am not sure if it corrects the behaviour of the group allocation though.

Build number : glusterfs-3.12.2-6.el7rhgs.x86_64

Tried out the steps in the description along with basic quota sanity over cifs mount. No issues seen.

Hence, moving bug to verified.
