You can try with a lights-out device or a PDU/UPS. But take into account that on split-brain, the off-site node may not be reachable. Often meatware is the only possibility in this case. Take a look here for fencing options http://www.clusterlabs.org/doc/crm_fencing.html Thanks, Dejan > -- > Regards, > Muhammad Sharfuddin | NDS Technologies Pvt Ltd | cell: +92-333-2144823 | > UAN: +92-21-111-111-142 ext: 113 > > The London Stock Exchange moves to SUSE Linux > http://www.computerworlduk.com/news/open-source/3260727/london-stock-exchange-in-historic-linux-go-live/ > http://www.zdnet.com/blog/open-source/the-london-stock-exchange-moves-to-novell-linux/8285 > > Your Linux is Ready > http://www.novell.com/linux > > > _______________________________________________ > 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
