Oy.  OK, these messages contain nothing but the answers to your
questions, but:

  Here's what I did:

  * partition each of my 500GB SATA drives (sda,sdb) as follows:

      - one 100MB primary partition
      - ten 50GB logical partitions (I have my reasons)

  * Create md raid 1 devices containing pairs of corresponding
    partitions from sda,sdb.

  * Set the 100MB RAID device to ext3, mount on /boot

  * Set the ten 50GB RAID devices to LVM

  * Choose "Configure Logical Volume Manager."  The thing tells me it
    needs to write the current partitioning scheme to disk....

        The partition tables of the following devices are changed:

          RAID1 device #1
          RAID1 device #10
          RAID1 device #2
          RAID1 device #3
          RAID1 device #4
          RAID1 device #5
          RAID1 device #6
          RAID1 device #7
          RAID1 device #8
          RAID1 device #9

        The following partitions are going to be formatted:

          Partition #1 of RAID1 device #0 as ext3

        Write the changes to disk and configure LVM?

  * OK

        [!!] Partition disks

        Error invorming the kernel about modifications to partitino
        /dev/md/1p1 -- Invalid argument.  This means Linux won't know
        about any changes you made to /dev/md/1p1 until you reboot -- so
        you shouldn't mount it or use it in any way before rebooting.

        ERROR!!!

See above.

Here:

  Furthermore, I've been here before, on different hardware.  This was
  on my Dell Inspiron laptop, not trying to do RAID:

  <link to report of same symptoms>

  And this seems to bear out that it's a known problem:

  <link to report of final solution>

  Now, what can I do about it?
