[linux-lvm] snapshots and 2.6 kernel

[Rich Turner]

i understand from numerous posts on this list and many others that
snapshots in the 2.6 kernel is not yet supported.

the lvm commands allow you to create the snapshot but do nothing with
it. even worse, i am unable to remove the snapshot or get the original
logical volume active.

is there any progress in the 2.6 kernel supporting snapshots?

is there any way to know if the snapshot will be valid before creating
the snapshot (other than 'uname -r')?

which is the culprit: device-mapper, lvm?
