I just manually started the mover and my syslog is generating a ton of errors: Not sure what SDAB is referring to.

Weird, so I shut down the server, swapped out an older 2TB drive (SDO) as I am upgrading the remaining 2TB drives in this server to 3TB drives, started the server back up, no more errors. I seem to suffer from phantom log errors from time to time, frustrating.
