Description Atin Mukherjee 2019-08-06 03:17:43 UTC

+++ This bug was initially created as a clone of Bug #1734534 +++


Description of problem:
When a user had edited the glusterd.vol file in /etc/glusterfs and updates the glusterfs packages, bricks cannot contact glusterd.

Version-Release number of selected component (if applicable):
glusterfs-6 and above (including mainline)


How reproducible:
Always

Steps to Reproduce:
1. install glusterfs-5 or lower
2. create and start a volume
3. edit glusterd.vol and  modify options like base port / max port
4. yum update gluster packages to glusterfs-6
5. restart volumes


Actual result:

bricks can't talk to glusterd

Expected result:

bricks should be able to talk to glusterd on 24007.

I think the change happened in c96778b354ea82943442aab158adbb854ca43a52 commit upstream and I propose that we fix this problem by keeping the default in code for glusterd and letting glusterd.vol override ride instead of having the value only in glusterd.vol.
