Hello.

I would like to know first if someone has sucessfully used rgmanager in this ML.
If so, how did you configure your cluster.conf, by hand or did you use a tool?
I searched over the archives and I only saw Jiho Hahm posting (twice) (16.02.2005) a question about rgmanager, and nobody answered.



I have configured it successfully, by hand.


Right now, there's a bug I'm working on which prevents it from working
properly in some configurations (namely: CMAN >2 nodes).  I should have
a permanent fix tomorrow or the day after.



Ok, because what I'm trying doesn't work:
I have three nodes debian, gump,buba.
debian exports devices to gump and buba over gnbd, and finally the three nodes have the same /dev/vg1/lv1 thanks to clvmd.
I created a script which mounts this gfs logical volume on /mnt/gfs and appends the name of the node in nodes_name.txt. (and stops writting and unmounting to stop), and I put this script as a resource.
I launch rgmanager and with clusvcadm I start, stop realocate the resource, this works very well!
But when I unplug the ethernet cable of the node running the resource, the resource isn't relocated to
another node, I suppose that's what you mean by it doesnt work with CMAN>2nodes.


If you need another tester to test your fixes here am I :)
