hi all
i have problem with lvm snapshot
suppose i create lvm of 50MB
i mounted it and create 5 blank files in that lvm partiton
i took the snap of that lvm with this command
lvcreate -L 16M -p rw -s data-backup /dev/vg0/lvolume
after some time i made 3 more files in that lvm partiton
now the lvm has 8 files but my snap data-backup has only 5 files
if i go to recover this snap i will get only 5 files
instead of 8 files
how can i update my snap also

"snapshot" as its name implies is a "picture" of a point in time.

You don't "update" a "picture" - you take a new one. Similarly you don't "update" a "snapshot" you simply take a new one.
