Hi all, I'm using LVM for all the partitions on my main hard drive (boot partition excepted) for the ability to take "snapshots" of the partitions at a particular point in time.
Anyway, while I have figured out perfectly how to take snapshots, mount them, and read/write to/from them, I have yet to find a good way to *revert* volumes (in particular, my root volume) to the state they were as of the snapshots. Currently, what I am doing to "revert" my root volume is: 1. Reboot from a separate volume with the Debian base system installed 2. lvcreate a new volume with the same size as my root volume 3. cp /dev/debian/snapshot /dev/debian/new_volume 4. lvrename /dev/debian/root /dev/debian/something_else 5. lvrename /dev/debian/new_volume /dev/debian/root This works fine. However, it is - of course - quite tedious, as it requires copying some 10GB worth of data. Does anyone know of a better way? Possibly using rsync? I may want to do this quite often in the future, as I plan on testing all sorts of somewhat-hairy things on this system and want to be able to easily revert to a snapshot. Tim
