Here's the lsof output for that directory: ubu...@ubuntu:~$ lsof /mnt/migrationassistant/home lsof: WARNING: can't stat() tmpfs file system /cow Output information may be incomplete. ubu...@ubuntu:~$ The system installed on /dev/sda1 has a separate /home partition. I wonder if this is part of what's causing the problem? I'll be unavailable for further testing for about the next five hours or so.
