Hello,
    I've got a single-drive CentOS5 system with two partitions on it, a 101 
mb boot, and the rest of the disk as an lvm volume, two partitions in it, / 
and swap. I've got another disk, same size, and i'd like to add it in as a 
primary slave drive and convert this system to raid1 for redundancy. I do 
not want to reinstall this box, which is what the docs i've read say it's 
easiest to do. Some elude to a procedure, hard yes, time consuming with 
copying probably, that can do it. Has anyone done this?
Thanks.
Dave.
