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 3.4.4 live(glusterfs-3.12.2-47.2.el7rhgs.x86_64) to 3.5.0(glusterfs-6.0-6.el7rhgs.x86_64)latest build
Version-Release number of selected component (if applicable):
glusterfs-6.0-6.el7rhgs.x86_64
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.
