Hello all,
I'm trying to install CentOS 6.3 to an mdadm partitionable array and not having any luck.
The installer only allows me to create one file system per md device, or specify the md device as a LVM physical volume. I don't want to do either, I want to create one md device and create multiple partitions on top of the md device.
I thought that perhaps the installer was preventing me from doing this because it wasn't possible to boot off a partitionable mdadm array, but through googling I don't believe this is the case. (See links at the bottom of this email)

Please see this thread from June/2012 on the subject matter
http://lists.centos.org/pipermail/centos/2012-June/126927.html
and the solution I found later on and posted in Oct/2012 -- http://lists.centos.org/pipermail/centos/2012-October/129654.html
I did install the latest dracut rpms per the bug reports listed in above but the fix is not 100% - for example if the second disk fails, I still get kernel panic
The first hit with search string "centos partitionable raid" gives me this http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 which is already discussed in my June post.
It does install if you follow the steps listed for release 6.
In retrospect, I would suggest stay away from this method. Go the traditional route; carve up the two disks per your requirements and make the md devices for root, boot, home etc.
