Recently, though I found myself wanting to use a snapshot logical volume to preserve the state of a filesystem while I experimented with changes. When I needed to revert, I had to copy the contents from the snashot logical volume, destroy the snapshot and snapshot source, and then replace the snapshot source with the copy I made of the snapshot. It seems like it would make sense for LVM to support a feature to revert the source logical volume to the state it was in when the snapshot was taken. I read through all the man pages but I didn't see anything like this. I realize it might not be possible to do this atomically while the source logical volume is active, but that's fine. I would still like to be able to do it when the source is inactive. </BODY> </HTML>
