BB release candidate problems with raid and LVM on install

[Eric S. Johansson]

just want to doublecheck to make sure I didn't do anything wrong before 
filing a bug report.

installing 5.10rc on Intel motherboard with 4 serial ATA drives.  I 
dedicated the first drive files from the installation.  Drives 2-4 are 
going to be configured as a raid one set with a single spare with LVM on 
top for managing partitions.

I was unfamiliar with how the partitioning tool would handle all of the 
partitions but eventually I got the raid set up correctly with drives 
2-4.  When I went to install LVM however, it tried to refer to 
partitions that didn't exist (i.e. /dev/md/0p1).

The question is, did I do something wrong or is this a real bug?

To reiterate, the sequence was:

Partition all disks
	hda: two partitions root and swap
	hdb: one partition raid
	hdc: one partition raid
	hdd: one partition raid spare

hdb-d assigned to raid set md0.
creating partition on raid set seems to fail with message about 
/dev/md/0p1 not existing.

pity, it was going so well...

by the way, installation on dell inspiron 5000 laptop was perfect (the 
second time).  I learned something about doing an online upgrade.  Only 
do it from a console, not from a remote ssh session.  whoops.
