pvcreate to raid1 fails

[Jerry Feldman]

Sure, I'll paste a full dump later on - not to the listserv.
I am running Fedora 12 with kernel 2.6.31.12-174.2.3.fc12.x86_64
Processor is an AMD Opteron Quad Core. 6GB memory.
LVM is lvm2-2.02.53-2.fc12.x86_64
The error message was copied and pasted:
[gaf at gaf ~]$ sudo pvcreate /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"

I've posted the details at: http://pastebin.com/4AtMzEjr

Note that my version of lvm2 is a bit behind the sources that you
reference.

Essentially, I back up my entire system using rsnapshot so I could
simply start from scratch and restore my backed up file systems and
allocate the raid1 volumes from scratch which is a backup plan, but I
would prefer not to do that and try to solve the problem.
