[linux-lvm] Snapshot validity

[sachin]

Hi All

I have a question.
What happen if i have change the configuration of the snapshot origin volume
i.e i may change the size of the volume .Is the snapshot is valid or its of
no use

What i think is data is of no use ,because internally the driver may
checking the
extent mapping of the origin of the  snapshot and then it scanning the
ioexception table
i.e COW table .If my assumption is not correct ,If any one knows the actual
working
Please tell  me .

Thanks
