Hello,
Could anybody point me where to find the internal structures of the COW
devices in /dev/mapper?
What I want to do, exactly, is: make a backup of the snapshot in an image
file, reading all the used blocks, and leaving the "not-used" ones. Later, I
want to get the image file, and restore the cow device. But I can't find an
LVM document that describes exactly how the COW structure is stored in disk.
Thanks,
Marconi Rivello.
