  I'm proposing a page to describe how to convert a running CentOS 5 system 
(though not while it is running) that was previously installed without RAID 
to a RAID 1 system using the CentOS install disk in rescue mode.  Since 
rescue mode is text based, there would be lots of differences.  There is a 
little overlap, mostly concepts.  I plan on including LVM, though I find LVM 
very annoying.

  I don't see any conflict or duplication between his page and my proposed 
page.  Actually, I see the pages as complimentary.

  If Phil is going to broaden the scope of his page, then, of course, I 
would withdraw my request.  However, I would recommend against having too 
much on a single page.
