The speed of the network doesn't really matter. It's useful to have the fencing on a *separate* network, as it would allow for the fencing of a node (and thus allow recovery to begin) when there is a network error that breaks cluster communications. This is mainly a 2-node issue though. -- Digimer E-Mail: [email protected] Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "At what point did we forget that the Space Shuttle was, essentially, a program that strapped human beings to an explosion and tried to stab through the sky with fire and math?" _______________________________________________ rhelv6-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv6-list
