But of course mirroring a 250 yields another 250? Course you should just be able to add one TB at a time via the hardware RAID tools: http://www.thegeekstuff.com/2008/07/step-by-step-guide-to-configure-hardware-raid-on-dell-servers-with-screenshots/ Unless you have a perc 6i: http://www.thegeekstuff.com/2009/05/dell-tutorial-create-raid-using-perc-6i-integrated-bios-configuration-utility/ Of course,I would dd the current disk image to backup (across the network or on a USB external drive) after booting into a Knoppix pendrive/LiveCD before starting anything so you can get it back. Once you have expanded your RAID 1 with 2Tb, you can add it back and resize: http://www.cclug.org/wiki/Main/KnoppixTricks I like to manipulate my img files in addition to hardware RAID before backup -- too many years of Perc - olation failures....! -- http://linuxgazette.net/165/kachold.html (623)239-3392 (503)754-4452 www.obnosis.com --------------------------------------------------- PLUG-discuss mailing list - [email protected] To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
