+++ This bug was initially created as a clone of Bug #1722131 +++

Description of problem:
During In-service upgrade, glusterd on upgraded node crashed with a backtrace,
when 'gluster vol status' command is issued from non-upgraded nodes.
Upgrade scenario is from glusterfs-5 or lower to glusterfs-6


Version-Release number of selected component (if applicable):
glusterfs 5 to glusterfs 6 upgrade

How reproducible:
3/3

Steps to Reproduce:
1. On three nodes cluster(N1, N2, N3), Create 2020 volumes of replicate(1X3)
and started them (Brick-mux enabled)
2. Mounted 3 volumes and running continuous IO from 3 different clients.
3. Upgraded node N1.
4. While heal is going on node N1, Ran 'gluster volume status' on node N2 which
is yet to upgrade.


Actual results:
glusterd crashed with a backtrace no backtrace seen.
