Subject: changing MD device
Date: Wed, 14 Jan 2004 16:44:39 -0500 [thread overview]
Message-ID: <4005B847.5090306@netscape.net> (raw)
I have a system up and running, the root directory is mounted on device
/dev/md0 which is a raid1 of 2 IDE drives. My question is, how can I
change it so that the my raid device is /dev/md1 not /dev/md0 and not
loose the data. Originally I was thinking of booting with a rescue
disk, breaking the raid1, and rebooting. Once rebooted create the raid
device again as /dev/md1. Is there a simpler way to do this?
Why do I want to do this? I have several external FC arrays with
software raid, and XFS file systems using an external log dev that is
/dev/md0 which is defined as a raid1 on the same array. I want to be
able to recover the external arrays - therefore my /dev/md0 on the
backup machine needs to change to /dev/md1.
TIA
