See also lvmsystemid(7).
This is sort of a hack, if I'm understanding correctly. Can we not
instead give the appliance a "system ID"?
Also, lvm(8) says:
--foreign
Cause the command to access foreign VGs, that would otherwise be
skipped. It can be used to report or display a VG that is owned
by another host. This option can cause a command to perform
poorly because lvmetad caching is not used and metadata is read
from disks.
which sounds bad.
