Hi!
What happens when the cluster network goes down completely?
Is the cluster silently using the public network without interruption, or does
the admin has to act?
The cluster network is used for OSD heartbeats and backfilling/recovery
traffic. If the heartbeats do not work anymore, the OSDs will start to
report the other OSDs as down, resulting in a completely confused cluster...
I would avoid an extra cluster network unless it is absolutely necessary.
