pvcreate to raid1 fails

[gaf-mNDKBlG2WHs at public.gmane.org (Jerry Feldman)]

I am migrating my system to a raid 1.
Given:
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units =3D cylinders of 16065 * 512 =3D 8225280 bytes
Disk identifier: 0x0003a96c

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1          25      200781   fd  Linux raid
autodetect
/dev/sdc2              26      121601   976559220   fd  Linux raid

ARRAY /dev/md1 UUID=3D05a09bd8:f968bb0e:91e28e81:d7bbf71d

[root at gaf gaf]# pvcreate -v -f /dev/md1
  /dev/md1: pe_align (128 sectors) must not be less than pe_align_offset
(36028797018963967 sectors)
  /dev/md1: Format-specific setup of physical volume failed.
  Failed to setup physical volume "/dev/md1"

Nore that /dev/md1 is formatted ext4.

Note that md0 contains 2 devices /dev/sda1 /dev/sdc1, but /dev/md1
contains only /dev/sdc2
What I am trying to do is to migrate my system (LVM on /dev/sda2) to raid=
1.
