Re: [Pacemaker] Crowdsourcing - Need a Pacemaker catchphrase
Hi, Supplemental explanation; We have the movie to promote Pacemaker in Japan. http://linux-ha.sourceforge.jp/wp/ Here is the long version(about 40 seconds). http://www.youtube.com/watch?v=D141O2U_nyc The main purpose of this movie is to let people know about Pacemaker, because many people still confuse Pacemaker and Heartbeat. Now, our boss got the additional budget to make the English version of this movie, (I was really surprised at this, he might have some magic wand.) so that's why, we need your help :) Please let me know if you have a good catchphrase for Pacemaker! By the way, the literal translation of a Japanese phrase is like this; Something is missing... Computer systems have used Heartbeat for a reliable zero downtime solution. Now, Heartbeat is evolving to the next level of high availability and robustness. That's Pacemaker! Pacemaker is the next generation of high availability clustering for Linux. Pacemaker achieves maximum availability for your cluster services by detecting and recovering from node and service-level failures. Now, for your high availability clusters, Use Pacemaker! I know Pacemaker is cluster manager, and Heartbeat is messaging layer, so there might be some misleading phrases, for example, "evolving" or "next generation". If there is the clear phrase to explain the connection of Pacemaker, Heartbeat and Corosync, it's the best one.

Good question, and indeed I don't know. It's conceivable that a clone set (remember, m/s are just clones with a little extra) has a clone-max that is less than the number of nodes in the cluster, and supports migration, and therefore a clone instance should be able to live-migrate to a different node. I have no clue whether it's indeed implemented that way, though.

[Pacemaker] announcement for glue 1.0.7 and heartbeat 3.0.4
Hello, The new releases of Heartbeat (3.0.4) and cluster-glue (1.0.7) are out. Please upgrade at the earliest possible opportunity. The highlights: - cluster-glue - external stonith plugins report now real exit codes (with Pacemaker 1.1 it could happen that say failed monitor operation is reported as success to the upper layers) - improved logging for stonith with Pacemaker 1.1 (should get rid of the annoying "parse error" log messages by fence_legacy) - new external/nut stonith plugin (Network UPS Tools) (thanks to William Seligman) - rename dtr|rts parameter to dtr_rts in rcd_serial; it was necessary to change it, otherwise it cannot be used in XML; NB: this is a regression for v1 users - optimization in logd and cl_log of logging to files - (note for Ubuntu users) the new ubuntu startup lrmd plugin is included but unfortunately not functional, it will have to wait for one of the next releases - Heartbeat - various optimizations at the communication layer - better support for Pacemaker 1.1 (make sure to use traditional compression) - new mcast6 UDP IPv6 communication plugin You can get the current tarballs here: Heartbeat: http://hg.linux-ha.org/heartbeat-STABLE_3_0/archive/STABLE-3.0.4.tar.bz2 cluster-glue: http://hg.linux-ha.org/glue/archive/glue-1.0.7.tar.bz2 Enjoy!

I think I've found the problem - comments below.

It does not appear to accept other variants, such as 'Cluster Monitor '; doing that results in the entire --mail-from argument being interpreted within angle brackets, which turns 'Cluster Monitor ' into <'Cluster Monitor' '>, which is a malformed sender address. Would the devs find it reasonable to accept a patch that uses something like regcomp() to check and see if the argument provided already contains a 'From: ', and if so, uses smtp_set_header() instead of smtp_set_reverse_path()? That would maintain backwards compatibility with the current style & give one the ability to form more complex From: addresses, since smtp_set_header() is passed through unchanged.

Please can anybody show me the error? It has to be somewhere very deep inside. I only want to have a two node cluster with apache load balanced and fail-overing. It shouldn't be that complex - but where is the error? Maby the solution or this configs will help others.

Re: [Pacemaker] lampp support
Hi, By lampp you mean Linux, Apache, MySQL PHP/Perl/Python? And what's stopping you from using the apache and mysql RA's? You want some kind of all-in-wonder? Try a resource group.
