I am using CentOS 6.2, mainly because that is that is what the "Clusters from Scratch" documentation uses. I am using GFS2.
Yeah, I had some issues with the cman/corosync/pacemaker startup order at first. But CentOS uses chkconfig which allowed me to turn corosync off, cman on and pacemaker on. Ever since, I haven't had an issue with the cluster coming up on its own. Previously I had to stop coryosync, start cman and then start pacemaker. I do seem to have some issues with the cluster recognizing when a resource is down but I believe that may be tied to pacemaker which I am using for fencing. There is something wrong with my cib.xml configuration. All the resources seem to be "docked" at Node2. If I cut Node2 off or unplug a network cable from Node2 than my cluster goes down. Even my cloned IP address goes down. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bruno MACADRE Sent: Thursday, August 02, 2012 2:38 AM To: [email protected] Subject: Re: [Linux-HA] Active/Active Hi, I'm working on a cluster of the same type as yours and I still ask myself some questions. Every feedback will be appreciated : - What OS did you use ? I do a lot of work on Ubuntu 12.04 server but I'm not satisfied by the cluster stability mainly with OCFS2 - Do you use clustered filesystem (like OCFS2 or GFS2) in you Dual Primary DRBD ? Did you have special concerns ? I had a lot of concern for use OCFS2 on Ubuntu server 'cause it need a cman stack above corosync which made entire cluster unstable. For example : When I do 'node standby node1' it kill pacemaker whithout the possibility to comme back online at all !!! - Have you been encountering some obstacles when NFS resources switch during high use ? I gladly give a look at your cib.xml file if you wish.
