Thanks Jim, but If i change iLO fence for a GNBD fence, results are the
same for my three questions, or do I need to configure one gnbd fence
for each node???

Hi all,
Sorry for this toppic, but i have serious doubts about using cluster
suite under some deployments. My questions:
a) How can I configure status check on a service script? for exmaple:
I have two nodes with CS U4 with postfix service running on two nodes
and using DLM as a lock manager. If I stop postfix from the script and
I wait status check, nothing happens and rgmanager returns an ok for
the service, but this service is stopped !!!.
b) is it posible to startup only one node on a two-node cluster? i
have tested this feature, but this node doesn't startup ( i am using
iLO as a fencing method, but I have tested gnbd too and the result is
the same).
c) why relocate service doesn't works?? I have attached my config.
For example, if I reboot one node, all services go to the second. This
is ok, but when this primary node is up, services continue getting up
in the previous node and they don't migrate towards the other node.
I suppose that I am doing something wrong but i don't know what.
Somebody can helps me??
many thanks.
Below in the conf file, you have one ilo device declared under the
fencedevice section, and both nodes are using it. This would mean that
if one node were ever fenced, then both nodes would be fenced. ilo is a
per node fence type - they are rarely shared. I think you should have a
fencedevice block of type ilo for each node, and then the fence section
under each node should ref the appropriate device....that is, node1
should use it's built-in ilo and node2 should use its own.
