CentOS - Feb 2013 - problem building partitionable RAID-1 on Centos-6

Trying to install Centos6 on my system (it's been running C5 for years).
I've got a pair of drives, so I'm trying to use RAID-1.

Previously I used a procedure where each partition was part of a separate
RAID device, but this time I'm trying the HOWTO from the Centos WIKI on
making a partitionable  RAID pair.

I've been having a lot of  problems, but have also been working thru them.

but t his latest one  has me stumped, I'd appreciate some advice.

Booting encounters a panic when trying to mount the RAID subsystem. you can
see an image of it at users.rcn.com/fredricksmith/panic.JPG.

Looks as if it's trying to boot from md127. there ain't no such critter,
where'd it get the idea it could boot from there?

or more importantly, how can I solve it?

thanks!


I may have to revert to the other method, but I figured this one was worth
a try.

Although the instructions work, there are pitfalls when one of the disk fails.

I sought help in this mailing list way back in June/July 2012 time
frame.   I would suggest you search the list archives of that period.

I did update dracut to the latest version but removing and restoring a
failed disk would not boot.

Posted the problem in the madm mailing list as well with no resolution.

I second the above option, if you have the luxury.  In the "other"
method, the system at least boots with one disk gone.
