Guys, how could I change node name and delete nodes after add into cluster? Connected by MOTOBLUR? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://oss.oracle.com/pipermail/ocfs2-users/attachments/20110512/28d3049b/attachment.html
It is a manual process until 1.6. The upcoming release of tools (1.8) will allow online modification and removal.

Then, copy the file to all hosts of the cluster. Stop the cluster (/etc/init.d/o2cb offline) and restart it (/etc/init.d/o2cb online). At least this worked for me.

Thomas Lau [12.05.2011 18:19]:> is it require to take the whole cluster offline ?!We did so. I do not want to imagine what happens if the nodes have different opinions about the allowed names... And when the filesystems are totally unmounted, you may even enlarge the number of node slots... you need to do this when you want to use more than the default number (5) of nodes in the cluster. BTW, Sunil mentioned the version 1.8 of the ocfs2 tools. Today I found them on the openSUSE buildservice in the network_ha-clustering repository. But I do not have the need to rename nodes right now ;-) Regards, Werner
