For people using LVM (or clvm) on shared storage, I encourage you to take
a look at two recent additions that you may find to be an improvement:

1. System ID

is for static ownership of VGs by hosts:

The nearest equivalent to system ID in the past has been configuring
lvm.conf filters uniquely on each host.

2. lvmlockd

is for dynamically sharing VGs among hosts:

Using lvmlockd with dlm is similar to what clvmd has done in the past.
Using lvmlockd with sanlock has no prior equivalent.

(For distribution packaging, see the "lvm2-lockd" rpm.)
