Thanks for the answer,


# /sbin/o2cb -V
o2cb.old 1.8.2

# /sbin/o2cb list-nodes --oneline storage
node: 1 tsc-hv01 10.251.2.11:7777 storage


but


#/tmp/o2cb -V
o2cb 1.8.0

# /tmp/o2cb list-nodes --oneline storage
node: 1 tsc-hv01 10.251.2.11:7777 storage
node: 2 tsc-hv02 10.251.2.12:7777 storage

strace is hard to read.


list-nodes --online prints the nodes that have been registered. If a node 
shows fewer than in the config file, then the cluster needs to be (re)registered 
on that node.

Hello Sunil,
 
we have critical issue in o2cb part of ocfs2 1.8.2 - getting list of node or 
adding node does not affect to ocfs2.conf. 
 
We have this issue on 3 different linuxes (kernel 3.2 - 3.8) so i thik this 
might be a sort of general o2cb problems.
