OK, if this ML is fine as well, I'll post it here:

Summary is that an active snapshot LV that loses its COW PV and is in
the same VG as the origin LV makes the origin LV disappear.

Example:
1. Create 2 PVs. Let's say /dev/sda and /dev/sdb
2. Create a VG with PV /dev/sda named data
3. Create a LV on VG data named origin
4. Extend VG data with PV /dev/sdb
5. Create a snapshot LV of LV origin, in VG data, on PV /dev/sdb, named snap
6. Remove /dev/sdb physically from the system (or disable in BIOS)
7. Reboot
8. Use vgreduce --removemissing to get VG data up again

LV origin is gone and can only be brought back from backup with
vgcfgrestore.
