Next time, try "vgreduce --removemissing <VG>" first.

In my experience, any lvm command using --force often has undesirable
side effects.


Regarding getting the lvm functioning again, there is also a --partial
option that is sometimes useful with the various vg* commands with a
missing PV (see man lvm).

And "vgdisplay -v" often regenerates missing metadata (as in getting a
functioning lvm back).
