[ClusterLabs] last man - issue

[Michal Pospíšil (he / him)]

Hi lejeczek,

Unfortunately, that command shouldn't work in this situation. The problem
is that the cluster (corosync) is running. From the man page:

update [auto_tie_breaker=[0|1]] [last_man_standing=[0|1]]
[last_man_standing_window=[<time in ms>]] [wait_for_all=[0|1]]
             Add, remove or change quorum options. At least one option must
be specified. Unspecified options will be kept unchanged. If you wish to
remove an option, set it to  empty  value,  i.e.
             'option_name='. Options are documented in corosync's
votequorum(5) man page. *Requires the cluster to be stopped.*

The output looks correct. More inline...

Corosync cannot be running to perform the requested corosync.conf update.

Because of `--skip-offline`, these two messages are warnings, not errors.

Error: swir: corosync is running

Turns out corosync is running on two other nodes, this is why pcs refuses
to continue. You have to stop the cluster, unfortunately.

Error: Errors have occurred, therefore pcs is unable to continue
