I created a snapshot with
lvcreate -n snap01.vm01 -L 5G -s vg0/vm01.eclabs.de
now I did some stuff on my disk i don't want to keep and want to revert it to the snapshot point.
How do I restore the snapshot?
I tried to copy the snapshot with
dd if=/dev/vg0/snap01.vm01 | pv | dd of=/dev/vg0/vm01.eclabs.de-restore
but although the file is only 5GB the dd process continues to copy things for hours. Is this sthe correct way?
