[ClusterLabs] Antw: [EXT] Recoveing from node failure

[Ulrich Windl]

Hi!

Did you take care for special "two node" settings (quorum I mean)?
When I use "crm_mon -1Arfj", I see something like
"  * Current DC: h19 (version 2.0.4+20200616.2deceaa3a-3.3.1-2.0.4+20200616.2deceaa3a) - partition with quorum"

What do you see?

Regards,
Ulrich
