Paul, I will have to clear the release of my config files through our security folks. It will take a couple days. Thanks for taking an interest.

When I change /etc/hosts and /etc/cluster/cluster.conf to use names "mynode1" and "mynode2" cman boots up correctly and I get a good cluster. If I change my configuration to use the interfaces named "mynode1-clu" and "mynode2-clu" which are defined in /etc/hosts I get an error: Cman not started: Can't find local node name in cluster.conf /usr/sbin/cman_tool: aisexec daemon didn't start However, if I do `hostname mynode1-clu` on the first node and `hostname mynode2-clu` on the second node and then restart cman I get a good cluster. I think this proves that my -clu interfaces are valid and properly defined in /etc/cluster/cluster.conf. This node was created from a disk clone of another cluster. Are there any cluster files that would retain system name or interface information? I have triple checked my /etc/hosts, /etc/sysconfig/network /etc/sysconfig/network-scripts/*eth* , /etc/nsswitch.conf, /etc/cluster/cluster.conf and dns files. Any suggestions would be appreciated.

If there is a master rgmanager instance, is it possible to identify which node it is running on ? regards, Martin -------------- next part -------------- An HTML attachment was scrubbed...

If that happens, you have a bigger problem than just using the qdisk label to identify the qdisk, don't you? ------------------------------ Message: 6 Date: Fri, 7 May 2010 09:57:51 -0400 (EDT) From: Bob Peterson <rpeterso@xxxxxxxxxx> To: linux clustering <linux-cluster@xxxxxxxxxx> Subject: Re: gfs rg and journal size Message-ID: <569169375.245311273240671353.JavaMail.root@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset=utf-8 ----- "Andrew A.

With gfs1, gfs_tool df tells you how many journals but it doesn't tell you their size, and there's no "journals" option in gfs_tool. You could use gfs_tool jindex, but the output is cryptic; it prints out the number of 64K segments, so 2048 corresponds to 128MB, assuming a default 4K block size.
