Question : About pcs cluster kill command.

[HideoYamauchi]

Hi All,

We installed pcsd0.9.148 on RHEL7.2.

[root@rh72-01 ~]# pcs status
Cluster name: cluster1
WARNING: no stonith devices and stonith-enabled is not false
Last updated: Wed Feb 24 13:48:41 2016 Last change: Wed Feb 24 13:48:35 2016 by hacluster via crmd on rh72-02
Stack: corosync
Current DC: rh72-02 (version 1.1.14-70404b0) - partition with quorum
2 nodes and 0 resources configured

Online: [ rh72-01 rh72-02 ]

Full list of resources:

PCSD Status:
rh72-01: Online
rh72-02: Online

Daemon Status:
corosync: active/disabled
pacemaker: active/disabled
pcsd: active/disabled

We executed pcs cluster kill command in rh72-02 node.

[root@rh72-02 ~]# pcs cluster kill

After having stopped, corosync and Pacemaker of the rh72-02 node reboot.

Feb 24 13:51:25 rh72-02 systemd: Started Corosync Cluster Engine.
Feb 24 13:51:25 rh72-02 systemd: Started Pacemaker High Availability Cluster Manager.
Feb 24 13:51:25 rh72-02 systemd: Starting Pacemaker High Availability Cluster Manager...

As a result, the rh72-02 node does not stop.

[root@rh72-01 ~]# pcs status
Cluster name: cluster1
WARNING: no stonith devices and stonith-enabled is not false

Is it right movement to reboot after kill command?
Or can you restrain reboot by setting?

Hi Hideo,

Running pcs cluster kill kills all cluster daemons. However systemd detects pacemaker is not running and starts it again. If you want to stop cluster on a node, run pcs cluster stop on that node.

Best Regards,

Hi Tomas,

Okay!

On RHEL7.2, we use the stop command without using the kill command.
I think that I want you to list this difference in a manual in the future.

Many thanks!
Hideo Yamauchi.
