[ovirt-users] Ovirt Node Heartbeat Settings

[Punit Dambiwal]

Hi Martin,

Yes...sometime the engine through the message in the event tab that host
not responding...but actually it's working fine....because of the engine
consider it as not responding...fence it....as i am using compute and
storage on the same node (glusterfs)...it cause me serious downtime in the
production...

Thanks,
Punit
