To be fair, that was on a slow 32bit windows xp in an old IE with probably old-ish java [*], and a default memory setting for plugin JVM or (I think) 64M. the config was very simple at that point, like two node, two drbd, one iSCSI target and lun and IP each, done from crm shell. After some time things became visible, but once you started to do something, it would start garbage collecting and never become responsive again. Once we started a standalone java, and adjusted the memory parameters to allow for 500 or 800 or so MB, it became useable. [*] so it may have been only the old java, even. who knows. I did not try to reproduce yet in any ways. But still, even on very simple configurations, the memory consumption of LCMC can be excessive, for whatever reason. -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. _______________________________________________ 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://bugs.clusterlabs.org
