Ocfs2 users - Oct 2005 - fencing timeout- increasing min time

What would the dangers/issues be within increasing the minimum time
before the fencing enforced panic of a node? We're hitting problems where
HBA multipath failover does not happen fast enough and we may need to up the
fencing timeout to something closer to 30-60 secs or more. Is this mostly a
performance impact or does it increase the window for corruption issues?

Looks like from the current code the min timeout is 4 secs.

For hardware/software details we're using CentOS4.1 x86_64 (clone of 
RedHat 4.1),
on a cluster of Sun v20z's, Opteron 250s. The cards involved are Emulex 
and multipath
is mdadm based.
