I have a small office samba server running redhat 9. The server was installed with two identical IDE hard drives as a raid1 mirror.

I'm starting to run low on disk space so I was thinking about breaking up the current mirror. I'd like to retain the master IDE drive to hold the current operating system, users accounts, smb.conf, etc . . .

Since this small server is a little cramped for space, I need to remove the slave IDE drive to open up a drive bay. With the current slave drive removed, I'll then have enough drive bays to install two new larger capacity drives and create a new mirror to hold data.

I think I can live with the o/s on a single drive since I have a weekly tape backup. However, I would like to have the extra layer of data redundancy by continuing to mirror our production data.

How difficult would it be to break up an exisitng raid1 mirror? If I simply remove the slave drive from the machine, will the server fail to boot? I'm wondering if I would have to edit /etc/fstab in order to do this.

Thanks in advance for the advice. This is the first linux server I have ever put in place, and fortunately, I've never had to try to recover from a mirror failure.
