OK, so you're talking about VM resurrections within OpenStack, via
the misnamed[0] "nova evacuate" API.

I agree - much more info required here, including cluster
configuration and the current state of resources (e.g. output of
crm_mon).

I am the upstream maintainer of the openstack-resource-agents project
which includes NovaEvacuate[1], so I will try to help if you can
provide enough information.  Although I suspect you are probably using
a vendor-provided version of NovaEvacuate and related files, is that
right?  If so, you might be better off obtaining support from that
vendor.

I assume "evacuations" means "recovered on the healthy node"?

Please share more information about your setup (program versions, OS)
and your configuration. Also, please share the log files from the
surviving node starting just before you crashed the node until a few
minutes after.

[ClusterLabs] IPMI working but evacuations don't work‏

2016-03-31 Thread Moiz Arif 
Hi,I am working on VM evacuations and i have noticed that when my compute 
node's network is disconnected there is call from STONITH to fence the node and 
my node gets rebooted. But the VMs are not evacuated. I have checked the logs 
and do not see the NovaEvacuate call. What can be the issue here? Thanks.Moiz
