OK.
 
It seems that the cluster realizes that something went wrong.
It wants to shutdown ha-idg-1:
Aug 03 01:19:12 [19367] ha-idg-1    pengine:  warning: pe_fence_node:   Cluster node ha-idg-1 will be fenced: vm-mausdb failed there
Aug 03 01:19:12 [19367] ha-idg-1    pengine:     info: native_stop_constraints: fence_ilo_ha-idg-2_stop_0 is implicit after ha-idg-1 is fenced
Aug 03 01:19:12 [19367] ha-idg-1    pengine:   notice: LogNodeActions:   * Fence (Off) ha-idg-1 'vm-mausdb failed there'
Aug 03 01:19:14 [19367] ha-idg-1    pengine:  warning: pe_fence_node:   Cluster node ha-idg-1 will be fenced: vm-mausdb failed there
Aug 03 01:19:15 [19368] ha-idg-1       crmd:   notice: te_fence_node:   Requesting fencing (Off) of node ha-idg-1 | action=8 timeout=60000
 ...

It shuts down ha-idg-2:
2022-08-03T01:19:51.866200+02:00 ha-idg-2 systemd-logind[1535]: Power key pressed.
2022-08-03T01:19:52.048335+02:00 ha-idg-2 systemd-logind[1535]: System is powering down.
2022-08-03T01:19:52.051815+02:00 ha-idg-2 systemd[1]: Stopped target resource-agents dependencies.
 ...

Then it stops cluster software on ha-idg-1:
Aug 03 01:19:58 [19361] ha-idg-1 pacemakerd:  warning: pcmk_child_exit: Shutting cluster down because crmd[19368] had fatal failure
Aug 03 01:19:58 [19361] ha-idg-1 pacemakerd:   notice: pcmk_shutdown_worker:    Shutting down Pacemaker
Aug 03 01:19:58 [19361] ha-idg-1 pacemakerd:   notice: stop_child:      Stopping pengine | sent signal 15 to process 19367
 ...
