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). Mike
