Hello all,
I have installed the OSS ocfs2 packages for Centos5; see below for
details. I've very carefully gone over everything, googled every
possibility I can think of, and I still cannot get two test machines
to share a drive, /dev/hdc. I have been at this for a couple of
days; I've configured with ocfs2console, rebooted multiple times,
with no success.
The front/public channel is 172.16.100.*, and the back channel is
172.16.101.* (the back channel is configured below); I can ping/ssh
across both channels without problem. The network connectivity is
good, and the IPs are right.
On the lvc8 system with the physical drive I can ocfs2 format and
mount /dev/hdc`. There is no information at all about that drive in
lvc4. I've looked through /sys/kernel/config many times. There is
no port 7777 traffic at all; I've sniffed eth0/eth1/any, and it
isn't there. iptables is stopped, there are not any filters active.
This is my my first foray into ocfs2, so I figure I must be missing
something very basic; I just don't know what. What might I try
next? Thanks much...
