[Linux-cluster] rhcs doubts.

[Allyson - Listas]

Hi guys,

I'm new at redhat cluster suite.  Could Anybody help me in some questions?

1st) I installed rhcs on 2 virtual machines and create a new cluster, 
setup a manual fence, a failvoer domain, create a IP resource and a 
service that uses just that IP for tests. Well, I'd like to know how can 
I force a failover of the service between nodes. This option is not 
available at system-config-cluster that allow just disable and enable 
the service.   I noticed that the ip service created is not a virtual 
interface like eth0:1, but it was working because I could ping it, Is it 
Normal?

2nd) What is the real fuction of a fence device?

3rd) How can I setup a quorum device, and isn't necessary for a failover 
service?  I read that it was needed at rhel3 but at rhel4 is not 
anymore, could you explain me that.


Any help is welcome :)

tks,
