Not very impressive :) Two different SATA II based arrays on an LSI controller, 5% complete in ~7 hours == a week to complete! I ran this command from an ssh session from my workstation (That was clearly a dumb move). Given the robustness of the pvmove command I have gleaned from reading, if the session bales how much time am I likely to lose by restarting? Are the checkpoints frequent?

I always use screen when running updates, installs, disk maintenance, etc. This way, if the ssh session dies for whatever reason, the command keeps going and I can reconnect to the session later. It's also useful to be able to start the run at the office and then reconnect from home to check on it.
