Our setup uses a hot-swap SCSI setup, whereas you're using ATA disks. Keep in mind that, to remove the drives, you'll more than likely need to shut down the system. Have the third drive in there as a back up will certainly buy you time. Follow the how-to I've written at https://www.secure-computing.net/wiki/index.php/Gmirror , and simply don't do any configuration on the third drive in the system. When one fails, you'll then remove, or 'forget' the failed drive, and add in the hot-spare you've got in the system. HTH ----- Eric F Crist Secure Computing Networks
