Yes, they are still mounted when I take a snapshot, I must have missed that
in the docs, that in itself poses a problem as I then cant umount the volumes
without killing services. I'd understood the snapshotting process as being
able to snapshot a live filesystem, and then mount the snapshot to perform
backups from it instead of the live filesystem. Whats the purpose of the
--size arg to lvcreate when taking a snapshot, I thought it was a buffer
to hold data that'd normally be written to disk but cant when the
snapshot exists? I'm confused.
