Hi list,
I am trying a two node cluster with RH 5.3 on Sun X4150 hardware. I
use a private network for heartbeat channel and fence_ipmilan for
fencing the two node. When I unplug the heartbeat channel cable, both
cluster nodes shut themselves down with fence_ipmilan.
I think the single point of failure for this design is private
heartbeat channel. I made a search on the web and there seems no
backup heartbeat channel (like LVS) on cluster suite.
How can I overcome this single point of failure problem?
One solution is I think, bonding heartbeat interfaces, however I use
all available interfaces and there is no extra interface for private
heartbeat channel. For this reason this solution doesn't suit me.
Anybody has an idea to overcome heartbeat channel failure problem.
