i work on redhat cluster from 2 years and i seen this topic so much times
this it's the problem with redhat cluster ping+quorum
If i have a two node cluster with public_net+private_net
I think it's normal my services switch if have the public network down on
the node
Sure. As long as you don't try to make use of any LVM features that require
metadata consistency (mirroring, snapshots, online resizing, etc.) you can get
by using LVM without clustering.

Hello Gianluca
Do you have a cluster private network?
if your answer it's yes i recommend don't use heuristic because if your
cluster public network goes down your cluster take a fencing loop
Or you can do something better, use pacemaker+corosync

Hello,
I have a cluster in RH EL 5.7 with quorum disk and an heuristic.
Current versions of main cluster packages are:
rgmanager-2.0.52-21.el5_7.1
cman-2.0.115-85.el5_7.3
This is the loaded heuristic
Heuristic: 'ping -c1 -w1 10.4.5.250' score=1 interval=2 tko=200
Line in cluster.conf:

We're talking 36TB of storage here.. I've never had much success
partitioning an array of that size (and actually being able to use all of
the space) without lvm. But I might give that a try.
Continuing along this line of thought:
If I stop access to the array from all of the servers before I ma
