[Bug 84821] Re: "attempt to access beyond end of device" when creating LVM snapshot

[Alasdair G. Kergon]

You need to improve your bug reporting skills:-)

Exactly what userspace commands did you run with exactly what options?
What is the architecture?  (Arch & chunksize interact.)

You also need to say what userspace versions of lvm2 & device-mapper you
are using - it's not necessarily a kernel bug.

There have been a lot of fixes to kernel device-mapper, including
snapshots, since 2.6.15.  So test against the latest upstream kernel and
userspace packages if you can and see whether or not the problem has
already been fixed there.
