I assume you're using Mikulas' shared snapshot kernel patches? E.g.:
http://people.redhat.com/mpatocka/patches/kernel/new-snapshots/r23/

And a patched lvm2 with shared snapshot support?  E.g.:
http://people.redhat.com/mpatocka/patches/userspace/new-snapshots/lvm-2.02.73/

It should be noted that the above shared snapshot work is unlikely to
make it upstream (portions of it likely will, for instance the lvm2
userspace changes).  A new shared snapshot implementation is in
development.

In any case, the easiest thing to do is use descriptive names for each
snapshot (include your own timestamp, etc).
