Subject: [EXT] [ClusterLabs] Need a help with "(crm_glib_handler) crit: GLib:
g_hash_table_lookup: assertion 'hash_table != NULL' failed"
Hello Andrew, Ken and the entire community!
I faced a problem and I would like to ask for help.
Preamble:
I have dual controller storage (C0, C1) with 2 VM per controller (vm0[1,2] on
C0, vm[3,4] on C1).
I did online controller upgrade (update the firmware on physical controller)
and for that purpose we have a special procedure:
1. Put all vms on the controller which will be updated into the standby
mode (vm0[3,4] in logs).
2. Once all resources are moved to spare controller VMs, turn on
maintenance-mode (DC machine is vm01).
3. Shutdown vm0[3,4] and perform firmware update on C1 (OS + KVM + HCA/HBA
+ BMC drivers will be updated).
4. Reboot C1
5. Start vm0[3,4]
On this step I hit the problem.
6. Do the same steps for C0 (turn off maint, put nodes 3,4 to online, put
1-2 to standby, maint and etc).
Here is what I observed during step 5.
Machine vm03 started without problems, but vm04 caught critical error and HA
stack died. If manually start the pacemaker one more time then it starts
without problems and vm04 joins the cluster.
Some logs from vm04:

As far as I understand, vm04 was killed by DC during the election of a new attr
writer?
The issue is reproducible from time to time and the version of pacemaker is "
2.1.5-8.1.el8_8-a3f44794f94" from Rocky linux 8.8.
I attached crm_report with blackbox. I have debug logs, but they are pretty
heavy (~40MB bzip --best). Please tell me if you need them.
Thanks,
Arthur
