Debain installer not detecting LVM

[monke2123]

Hello everyone,
I'm having trouble getting the debian installer to detect an existing LVM

I installed Lenny on LVM on top of RAID 1.
My system looks like this

2x 500GB RAID 1
/boot - /dev/md0
/ - /dev/md1
swap
LVM rest of the disk:
/home - /dev/vg0/home
/usr - /dev/vg0/usr
/var - /dev/vg0/var
/tmp - /dev/vg0/tmp

I just added two 1.5 TB drives in raid 1 to the logical volume group home

100% added to /home /dev/md3

I went to reinstall the system from the lenny disc and now the installer does not recognize the LVM. It did recognize the LVM before I added md3 to the LVM.

During the partition editor, if i go to a terminal (by going to another window/console) and give the command vgdisplay it says that physical volume with UUID V0S1Yx-361r-NZaE-w1Fy-kCFQ-9MmH-g287vh cannot be found. You will see below that the UUID refers to /dev/md3 (the added 1.5 raid 1 array)

Below is the output of "pvdisplay" and "mdadm --detail /dev/md3"

I don't know if this has to do with it but /dev/md3 is the only array that says local to host yield [yield is my hostname] next to its UUID after the mdadm --detail command

Please let me know if you have any ideas or if should provide more info/commands

Thanks in advance

I hope someone with the right knowledge base answers this because I need to attempt the same thing soon. I don't think that this is so much a Debian issue as a hardware (recognition) issue though.
