I did some more testing with that trusty system and it does appear to be
working much better than before (i.e. not at all), though it seems there

causes (100.00% full snapshots) that it then no longer tries to extend,
but
@Donk yes, of course.

It looks like it works on Ubuntu 16, syslog contains things like:
Feb 10 11:28:55 hostname lvm[1704]: WARNING: Snapshot vgname-lvname is now
80.03% full.
Feb 10 11:28:55 hostname lvm[1704]: Size of logical volume vgname/lvname
changed from 1.00 GiB (256 extents) to 1.20 GiB (308 extents).

On Ubuntu 14, it doesn't seem to work with monitoring = 1 set, either. I
had also tried doing vgchange --monitor y --poll y volumegroup, and
lvcreate --snapshot --monitor y ... and there was no effect.
Testing on Ubuntu 16 now
