As i mentioned before: i wasn't able to reproduce your problem on any of
my systems. It work just fine with 0.8final and in 0.9 as weel.
Did anybody else beside Rik face a problem with snapshots _not_ referring
to the original logical volume they where created for?

I don't have any complaints so far about similar snapshot malfunctions
you mentioned, Rik.
That said it is overemphasis to say, that the LVM utilities
are not working.
IMHO Andreas Dilger's LVM 0.8 backport to kernel 2.2 should be o.k. for
most of the cases.
I'ld like to have 0.9 to do the integtration of the available patches
which will be released in november.
