I read it in the "Configuration Explained" pdf ... Advisory Ordering ... and it is also mentioned in your "Ordering Explained" pdf. By the way, I found it a little bit confusing that "from" and "to" are interchanged in "Ordering Explained" without mentioning that this is not the default behaviour ( type=after ) ... e.g. : <rsc_order from=A to=B> Start A before starting B and stop B before stopping A ... or A and B are interchanged, as you prefer ;-) Regards, Andreas > > > _______________________________________________ > Linux-HA mailing list > [email protected] > http://lists.linux-ha.org/mailman/listinfo/linux-ha > See also: http://linux-ha.org/ReportingProblems > _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
