[Ocfs2-tools-devel] ocfs2-tools-o2cb-1.8.2 - critical issue o2cb

[Eugene Istomin]

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.


#####

Here is some debug info

# cat /etc/ocfs2/cluster.conf
cluster:
        heartbeat_mode = global
        node_count = 2
        name = storage

node:
        number = 1
        cluster = storage
        ip_port = 7777
        ip_address = 10.251.2.11
        name = tsc-hv01

node:
        number = 2
        cluster = storage
        ip_port = 7777
        ip_address = 10.251.2.12
        name = tsc-hv02



In ocfs2 1.8.0 (return 2 nodes):
# strace -s 2048 ./o2cb list-nodes --oneline storage
