You don't mention what storage setup you are using but if you have
multipath storage then you will need to configure filters in
/etc/lvm/lvm.conf to exclude the individual paths and ensure that LVM2
only uses the multipath devices.

If this isn't the problem you're having then you're going to need to
describe your situation in more detail (include command output & a
description of your environment) for people to be able to help you.
