As a result of a strange situation where our licensing for storage
dropped off, I need to join a centos 5.6 node to a now single node
cluster. I got it joined to the cluster but I am having issues with
CLVMD. Any lvm operations on both boxes hang. For example, vgscan.
I have increased debugging and I don't see any logs. The VGs aren't
being populated in /dev/mapper. This WAS working right after I joined
it to the cluster and now it's not for some unknown reason. Not sure
where to take this at this point. I did find one weird startup log
that I am not sure what it means yet:
[root@omadvnfs01a ~]# dmesg | grep dlm
dlm: no local IP address has been set
dlm: cannot start dlm lowcomms -107
dlm: Using TCP for communications
dlm: connecting to 2
That message usually means that dlm_controld has failed to start. Try
starting the cman daemons (groupd, dlm_controld) manually with the -D switch
and read the output which might give some clues to why it's not working.

Hi Chrissie,
I thought of that but I see dlm started on both nodes. See right below.
[root@omadvnfs01a ~]# ps xauwwww | grep dlm
root 5476 0.0 0.0 24736 760 ? Ss 15:34 0:00
/sbin/dlm_controld
root 5502 0.0 0.0 0 0 ? S< 15:34 0:00
Well, that's encouraging in a way! But it's evidently not started fully
or the DLM itself would be working. So I still recommend starting it
with -D to see how far it gets.
