Description Byreddy 2017-01-03 11:13:22 UTC

Description of problem:
========================
gNFS Server is not coming up for the 3.1.3 volume after updating to  3.2.0.

I had two nodes cluster in 3.1.3 with Dis-Rep ( 2*2 ) volume and done the in-service update to 3.2.0 by fuse mounting the volume.

After updating all cluster nodes, bumped up the cluster op-version to 30901 and checked the volume status, in v status, NFS Server was showing N/A.


NFS Server should be running for the upgraded volume as per the BZ-https://bugzilla.redhat.com/show_bug.cgi?id=1404996



I will provide the sos reports from server nodes to check the issue.

Version-Release number of selected component (if applicable):
==============================================================
Update from 3.1.3 to glusterfs-3.8.4-10.



How reproducible:
==================
Always

Steps to Reproduce:
===================
1. Have two node cluster and have 2 *2 volume.
2. Fuse mount the volume and start IO
3. Start In-service update ( follow the steps present in installation guide)
4. Check the volume status // you won't see NFS Server running.

Actual results:
===============
NFS Server is not coming up after updating 3.1.3 volume to 3.2.0 latest build.


Expected results:
=================
NFS Server should be running as per the BZ-https://bugzilla.redhat.com/show_bug.cgi?id=1404996

Upstream patch http://review.gluster.org/16316 posted for review.

Comment 5 Atin Mukherjee 2017-01-03 12:57:15 UTC

RCA: op-version bump up code handled the upgrade path for all existing volumes for which gNFS was not disabled however the code didn't reconfigure the nfs daemon because of which nfs service was never started.

(In reply to Atin Mukherjee from comment #4)
> Upstream patch http://review.gluster.org/16316 posted for review.

The behaviour in upstream is different where user is supposed to explicitly enable gNFS post upgrade. So this patch will not be valid in upstream. I'll be working on a DOWNSTREAM ONLY patch to fix it.

Comment 7 Atin Mukherjee 2017-01-03 16:46:05 UTC

Comment 6 is correct and hence closing this bug.

Comment 9 Atin Mukherjee 2017-01-03 16:48:47 UTC
