how to convert to RAID-1 in place?

[Jack Howarth]

Roberto,
    How about the protocol I posted at...

https://www.redhat.com/archives/fedora-list/2006-March/msg04350.html

This is based off the instructions at...

http://wiki.archlinux.org/index.php/Convert_a_devfs_single_drive_system_to_RAID

and

http://www.epimetrics.com/topics/one-page?page_id=421&topic=Bit-head%20Stuff&page_topic_id=120

My understanding is that I can avoid the resizing issue with the RAID-1
conversion using the approach of creating the RAID partitions on the second
drive and copying the data over to them. Once I can boot from the second
drive using the md partitions I can use the partitions on the first drive
as spares and not worry about the resizing issue.
