[ClusterLabs] STONITH forever?

[Stefan Schlösser]

Hi,

I have a 3 node setup on ubuntu 16.04. Corosync/Pacemaker services are not started automatically.

If I put all 3 nodes to offline mode, with 1 node in an "unclean" state I get a never ending STONITH.

What happens is that the STONITH causes a reboot of the unclean node.

1) I would have thought with all nodes in standby no STONITH can occur. Why does it?

2) Why does it keep on killing the unclean node?

The only way to stop it, is to temporarily disable stonith and bring the unclean node back online manually, and the enable it again.

Here is a log extract of node c killing node a:

This the repeats forevermore ...

Thanks for any hints,

cheers,

Stefan
