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 [root@omadvnfs01a ~]# ps xauwwww | grep dlm root 5476 0.0 0.0 24736 760 ?
