[Linux-cluster] RHEL4AS w/ cvs RHEL4 branch

[Rodriguez, Antonio]

Thanks Dave! 

Now I know what my problem is.

Now I'm trying to use fence_brocade as my fencing method, and I have
this error when I simulate a failed node, or when I run the command
fence_brocade:

Please help.

You should run 'fence_ack_manual' on the surviving node (you've
obviously
just restarted the failed node by pressing its power button.)

The special two_node option allows the cluster to have quorum even
though
there's only one node remaining.  Everything should run normally on the
surviving node after you do the manual ack.  Using SAN fencing with the
brocade will eliminate this manual step.
