[Ocfs2-users] Adding new nodes to OCFS2?

[Nuno Fernandes]

Do:

o2cb_ctl -C -i -n dbcl1n5 -t node -a number=4 -a ip_address=192.168.201.5 -a 
ip_port=7777 -a cluster=dbcl1

on all nodes.  It automaticaly updates cluster.conf e add on-the-fly the 
nodes. 

Check faq and make sure you understand all command line options.
