[linux-lvm] Reading Cow table

[sachin]

Hi Everyone
Can any one tell  me is it possible to read the cow table & find out the =
exact location of the data on the disk or partition . If yes give me any =
clue to read the COW table and other data.

I am using a lvm 1.0.3  . Copy of the cow table should be consistant with
the data on disk

Thanks in advance.

Not supported directly.

If you're up for some investigation, look at the on-disk format definitions
for COW in lvm.h and check into the *COW*() lib functions.

I presume you are talking about snaphots ?  If so which version of LVM are you running ? - Joe
