[Linux-HA] Heartbeat v1 and stonith/stonith_host ipmilan
Hi folks! I have a 2-node setup for MySQL HA. The two nodes access a shared set of SAS disks over a backplane. The services/resources are: an IP address, an LVM VG, two mountpoints and MySQL. Using heartbeat 3.0.4 with a v1 configuration this is a piece of cake. Except apparently for stonith. The documentation hints that stonith and stonith_node should be available when using v1 configurations. And a grep through current sources seems to indicate it's still supported. But the 'stonith' script/binary and the scripts that the old documentation indicates aren't there anymore (when I install on RHEL6.4). I do have fenced (from cman) and fence_ipmilan (from fence-agents) which looks like it should work for these boxes. Can heartbeat 3.x, using a v1 config, drive fence_ipmilan or some equivalent node? Any hints how, or how to explore/discover/debug? Please CC me. thanks! m ps: yes, I know about more modern facilities. trying really hard to keep this simple... -- martin.langh...@gmail.com - ask interesting questions - don't get distracted with shiny stuff - working code first ~ http://docs.moodle.org/en/User:Martin_Langhoff ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems

Configuring stonith_host external foo bar baz led me in the right direction. heartbeat knows what to do, but on RHEL/CentOS/SL 6.x cluster-glue no longer includes stonith agents. Some info at http://www.gossamer-threads.com/lists/linuxha/pacemaker/74487 So I rebuilt the RPMs for cluster-glue reversing that removal. It is a dicey proposition, of course, to setup a cluster that I expect to be long-lived based on software that folks are running to deprecate. But I have played with corosync + pacemaker extensively, and TBH they are way overkill for a simple setup. Is there a _simple_ setup guide for a two node cluster? Y'know, LVM, couple mountpoints, one server daemon (mysql)? I am not afraid of complexity; but I like to pick where to invest in complexity :-) cheers, m -- martin.langh...@gmail.com - ask interesting questions - don't get distracted with shiny stuff - working code first ~ http://docs.moodle.org/en/User:Martin_Langhoff ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems

The configuration you are describing will be simple and will be properly supported until 2020 (at least), and not need hacks. If you're interested in this approach, I can help. Here or on #linux-cluster on freenode's IRC. Thanks for the offer to help. Is there any clear setup guide you can point me to? My TZ is EDT, so midnight (bedtime!) now. I won't be awake and on email/irc until tomorrow morning. m -- martin.langh...@gmail.com - ask interesting questions - don't get distracted with shiny stuff - working code first ~ http://docs.moodle.org/en/User:Martin_Langhoff ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
