See the man pages for vgcreate and vgchange, and particularly the
options: -c, --clustered.

Subject: [rhelv5-list] Vgimport / vgexport question

With LVM2 (RHEL5), if I have multiple systems that see the same LUNs,
how do I stop all the systems from importing / exporting the volume
groups when I issue a vgimport or vgexport on one of the systems?

Configuration:
hostA and hostB see the same SAN LUNs.  I've created each LUN as a PV
(pvcreate).  I've created a VG with vgcreate using one of the LUNs.
When I import the VG on hostA, it also shows up as available on hostB.

Is there a way to prevent that, so that the VG is only available on the
host that I issued the command on?
