Re: [ClusterLabs] corosync service stopping
Hi Honza I would say there is still a certain ambiguity in "shutdown by cfg request”, but I would argue that by not using the term “sysadmin” it at least doesn’t suggest that the shutdown was triggered by a human. So yes, I think that this phrasing is less misleading.

[ClusterLabs] corosync service stopping
Hi all, I’m trying to get a better understanding of why our cluster - or specifically corosync.service - entered a failed state. Here are all of the relevant corosync logs from this event, with the last line showing when I manually started the service again: Apr 23 11:06:10 [1295854] testcluster-c1 corosync notice [CFG ] Node 1 was shut down by sysadmin Apr 23 11:06:10 [1295854] testcluster-c1 corosync notice [SERV ] Unloading all Corosync service engines.

The ‘sysadmin’ surely must mean a person logging on to the server and running some command, as opposed to a system process? Then in the 3rd row from the bottom there is the warning “host: host: 1 has no active links” which is followed by “Corosync Cluster Engine exiting normally”. Does this mean that the reason for the Cluster Engine exiting is the fact that there are no active links? Finally, I am considering adding a systemd override file for the corosync service with the following content: [Service] Restart=on-failure Is there any reason not to do this? And, given that the process exited normally, would I need to use Restart=always instead?
