Sorry if this is on the FAQ but I can't seem to find it.
Has anyone had any experience with using LVM and Locking Type 3
(internal cluster locking).
I have attempted to use this primarily to put LVM on a SAN.
However, when I try to create the physical volume initially I get:
[root at somehost ~]# pvcreate --verbose /dev/sdb
  connect() failed on local socket: Connection refused
  Locking type 3 initialisation failed.

Effectively stopping this technique.  Is RHEL4's version of LVM not
compiled --with-cluster=internal option?
Any help / hints are greatly appreciated.

Best Regards,
