Good RAID HowTo

[Brian C. Huffman]

All,

I'm trying to find a good RAID howto on migrating from a non-mirrored
disk to a mirrored configuration both for the root filesystem as well as
others.  

Everything I'm finding is *extremely* dated.  This shouldn't be that
difficult - I've done it w/ Solaris a million times.  :-)  However, I'm
concerned with gotchas in Linux.

Can anyone offer some pointers?  Sorry that this is somewhat off topic
for this list.

Thanks,
Brian

Hi Brian,

Off topic indeed :) This is for Fedora test releases only.

Try the general user list instead, it has a larger audience and people
are more likely to answer such questions: fedora-list(a)redhat.com

Good luck!

Software RAID or hardware one? What exactly do you want/need?

Software is easy:

This is a bit dated, but it'll work just fine never-the-less.

As for hardware, it depends on the type of hardware used.

Be aware that the perfect companion for MD software raid is LVM.

Software raid? or hardware raid? If hardware it's easy. Just ad the
drive to the array and then go into the bios of the raid card and setup
the first drive as master and then add the other drive. Set it to raid
0... your done. 

If software are you going to use different drives?
