You wanted to say "sequential == false"? > For some reason the shell appears to be setting that by default. This is sequential == false: colocation together inf: ( dummy1 dummy2 dummy3 ) dummy4 This is sequential == true: colocation together inf: dummy1 dummy2 dummy3 dummy4 Thanks, Dejan > > > > > To pick up Vadym's Question: > > > > * what would be the correct syntax to say > > "run-together-but-dont-care-if-one- > > dies-or-is-not-runable"? > > Choose a score < inf, just like regular colocation constraints. > > > > > Regards, > > Andreas > > > >> > >> > colocation still has to be honored. > >> > > >> > If I am wrong, what syntax I should use to achieve the described > >> > configuration? > >> > > >> > Thank you, > >> > Vadym Chepkov > >> > > >> > > >> > > >> > _______________________________________________ > >> > Pacemaker mailing list: Pacemaker@oss.clusterlabs.org > >> > http://oss.clusterlabs.org/mailman/listinfo/pacemaker > >> > > >> > Project Home: http://www.clusterlabs.org > >> > Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf > >> > Bugs: > >> > http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker > >> > >> _______________________________________________ > >> Pacemaker mailing list: Pacemaker@oss.clusterlabs.org > >> http://oss.clusterlabs.org/mailman/listinfo/pacemaker > >> > >> Project Home: http://www.clusterlabs.org > >> Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf > >> Bugs: > >> http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker > >> > > > > _______________________________________________ > > Pacemaker mailing list: Pacemaker@oss.clusterlabs.org > > http://oss.clusterlabs.org/mailman/listinfo/pacemaker > > > > Project Home: http://www.clusterlabs.org > > Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf > > Bugs: > > http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker > > > > _______________________________________________ > Pacemaker mailing list: Pacemaker@oss.clusterlabs.org > http://oss.clusterlabs.org/mailman/listinfo/pacemaker > > Project Home: http://www.clusterlabs.org > Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf > Bugs: > http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
