proposed fix

Hi David,

this is a proposed patch to address the problem. If FENCE_NO_JOIN is set, we
skip both invokation of fence_tool join and fence_tool leave.

Similar patch (modulo offset) applies to virtually all branches.

Comment 3 Ryan O'Hara 2008-07-28 15:59:08 UTC 
Fixed.

Added variable to FENCE_JOIN to control whether or not the script attempts to
join the fence domain. If FENCE_JOIN is set to "no", the script will not attempt
to join/leave the fence domain for start/stop respectively. If FENCE_JOIN is set
to any other value, the init script will follow the default behavior, which is
to join/leave the fence domain.

Note that this effects fence_xvmd, too. If FENCE_JOIN is set to "no", we also
skip the fence_xmvd step(s) in the init script.

Changed title of this BZ to reflect actual name of variable. Decided that
FENCE_JOIN with yes/no value is most agreeable format for doing this sort of
control.
