[ogfs-users]RE: Problems with opengfs + opendlm on RHEL 3
Solved the problems I was having before by removing all existing
ultramonkey heartbeat rpms (including libnet) and compiling from src. I
also needed to use LD_ASSUME_KERNEL=2.4 on top of all of that.
So now that I got it working I'm running into further problems, some of
which I can work around and others I'm struggling to understand how to
fix.
Problem 1: Mounting more than one ogfs filesystem with opendlm does not
seem very stable at all, true? Not a biggie for me.. I can run just one
big filesystem if necessary.
Problem 2: Recovery is not very well documented.. how do you do it!?!
I setup my 2 nodes with an opendlm mount. I then unmount one of the
nodes and stop the dlm and heartbeat. Any attempt to have that node
rejoin results in failure. the dlms seem to resume communications ok
after restarting things in order (and I even tried a full reboot too),
but the mount command just hangs. During all of this the mount on the
second node stays up which is good.. but oddly I can't seem to unmount
that node cleanly?
What is the correct procedure for recovering from this scenario while
maintaining high availability?
Am I doing something wrong?
Thanks!
