You probably need to start up the cluster infrastructure. cman, ccsd,
fencd, and clvmd.

This is probably not a good idea, but you can also turn off LVM2 locking
with:

lvmconf --disable-cluster

you can turn LVM2 locking back on with:

lvmconf --enable-cluster --lockinglibdir /usr/lib --lockinglib liblvm2clusterlock.so

The lvmconf command edits /etc/lvm/lvm.conf.

The errors 'connect() failed on local socket: Connection refused' appear
from LVM2 commands when clvmd is not running and lvm.conf is configured
for a cluster.

I am not sure why the device name does not show up.  After turning off
locking, you could try to do a 'vgchange -ay' and hopefully it will
appear.
