Hello,
I have a RHEL 6.5 cluster, using rgmanager.
The fence devices are fence_ipmilan - fencing through HP iLO4.
The issue is the fence devices weren't configured entirely correct - recently after a node failure, the fence agent was returning failures (even though it was fencing the node successfully), which apparently can be avoided by setting the power_wait option to the fence dev configuration.
My question is - after changing the fence device (I think directly through the .conf will be fine?), iterating the config version, and syncing the .conf through the cluster software - is something else necessary to apply the change (eg. cman reload)?
Will the new fence option be used the next time a fencing action is performed?
And lastly can all of this be performed while the cluster and services are operational or they have to be stopped/restarted?
Regards,
Vasil
