Re: [opensuse] OT: Expanding RAID size
Chris Arnold wrote:
OK, i know this is not an opensuse question but i want to see what others have to say about this.
I currently have an ibm xserver running SLES 10 SP2 with 2 drives of 36gb a piece (this is an active/production server) in raid 1 (hardware). I want to replace those 2 drives with larger drives without losing any data. What i have tried so far is to remove one of the 36gb drives and install 1 of the larger drives and hope that it would rebuild and see the "extra" space. But this does not appear to work. What is the correct way to do this?
Just set up a second raid volume with the new drives and migrate the desired directories to the new volume.
The server is a 1u rack and only has 2 drive slots so it is impossible to setup another volume with this server with the larger drives installed. This config seems to make it a little harder to expand to larger drives -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

This is another example of what a good backup can do for you. Do a full backup swap the drives and restore the data. -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You _might_ be able to make this work: (no guarantees offered) 1) fail and remove drive B from the array. (A1) 2) replace drive B with newer/bigger drive. 3) create new array (A2) using only drive B. 4) copy your data from A1 to A2, then prepare the system for booting/running off A2. 5) reboot (sorry, unavoidable AFAICS). 6) stop A1, replace physical drive with newer/bigger. 7) add drive A to array A2. /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
