Sorry about spamming the list, but I figured it's probably best to ask more specific questions and give a better idea of what it is I'm trying to accomplish.
I have 2 node cluster, active/passive. They are currently test systems that have not gone into production. They are both going to be running MySQL, and HA. My client wants me to figure out how to intergrate STONITH with HA on this system. From what I can tell it's running HA version 3. Or at least that's what I'm guessing from the output of rpm -qa | grep heartbeat. The client does NOT currently have a CRM (Like pacemaker or anything like that) and they do not want anything like that installed as they believe it makes the situation more complicated than it needs to be. However, the client also wants it configured so that if someone logs into the machine and inititates a failover by doing 'service heartbeat stop' the STONITH will not occur, but if a failover occurs automatically (like the heartbeat just failing) then STONITH should occur. Unfortuantly I normally work on the DB side of things so I have not had much exposure to HA. With all of this in mind here are some more specific questions that might help. 1) Can I run stonith from a BASH prompt or does it need to be controlled elsewhere? 2) Can I even use STONITH without having a CRM installed? 3) Can I code it so that STONITH will only work under certain conditions? - Peter On Tue, Aug 3, 2010 at 5:48 PM, Peter Sylvester <[email protected] > wrote: > I did check out the man pages.
