Have you considered just resizing the volumes? If you're trying to swap them with rsync, you're going to have to reboot anyway, and relabel your system. If any daemons are running, you might also corrupt their data this way. > The entire /var partition is only using 549MB: > > rsync: write failed on "/opt/var/log/lastlog": No space left on device (28) Depending on what UIDs are allocated to your users, lastlog can be an enormous sparse file. You would need to use rsync's -S flag to copy it.
