hi list, I am using ocfs2 on Ubuntu 16.04.3 Linux servers. The ocfs2 packages provided by apt-get includes the "o2cb_ctl" and "ocfs2console" utilities. my Ubuntu servers do not have a GUI so I can't use the graphical "ocfs2console" utility. I can use the "o2cb_ctl" -C option to add nodes to the cluster config. -C Create an object in the OCFS2 Cluster Configuration. But it seems the "o2cb_ctl" -D option, to remove a node, is not implemented in this version of the tool -D Delete an object from the existing OCFS2 Cluster Configuration. root at node-9:~# o2cb_ctl -D -n node-6 -u o2cb_ctl: Not yet supported But I need to remove a number of old nodes that no longer exist. I was just leaving the old nodes in there and adding in new nodes, but now I need to add a node which has the same ip address as one of the old nodes.... so, I need to delete that old node. it seems to me there would be a manual way to do this. change the cluster.conf file and apply the changes on the fly. I need to keep the ocfs2 filesystem up while removing old nodes on a number of servers. can anyone tell me the manual steps to do this on each of my servers? The rest of my environment needs to run on Ubuntu 16, otherwise I would try ocfs2 on a different OS. I see there is a newer tool, named O2CB (NewO2CBTool), which may help me out, but is there source code for it? and will it compile on Ubuntu 16.04.3? thanks! -- Jim -------------- next part -------------- An HTML attachment was scrubbed...
