FC2 -> FC3 issue with Partition table entries not in disk order

Hi,

I have two pretty much identical servers, each with a
Linux software RAID 1 mirror comprised of 2x 9Gb
disks.

On of them I installed a fresh FC3 copy (call it
server1), with the following disk layouts:

# fdisk -l /dev/sda

Disk /dev/sda: 9056 MB, 9056904704 bytes
255 heads, 63 sectors/track, 1101 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id
 System
/dev/sda1   *           1          13      104391   fd
 Linux raid autodetect
/dev/sda2              14         407     3164805   fd
 Linux raid autodetect
/dev/sda3             408         774     2947927+  fd
 Linux raid autodetect
/dev/sda4             775        1101     2626627+   5
 Extended
/dev/sda5             775         905     1052226   fd
 Linux raid autodetect
/dev/sda6             906        1036     1052226   fd
 Linux raid autodetect
/dev/sda7            1037        1101      522081   82
 Linux swap

on other one (call it server2) I did the same thing in
terms of disks, but as it was already an FC2 server, I
went through the upgrade process using the FC3 CD's to
upgrade the OS.

The following is the disk layout of server2:

# fdisk -l /dev/sda

Disk /dev/sda: 9056 MB, 9056904704 bytes
255 heads, 63 sectors/track, 1101 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id
 System
/dev/sda1   *           1          13      104391   fd
 Linux raid autodetect
/dev/sda2            1037        1101      522112+  82
 Linux swap
/dev/sda3              14         407     3164805   fd
 Linux raid autodetect
/dev/sda4             408        1036     5052442+   5
 Extended
/dev/sda5             408         774     2947896   fd
 Linux raid autodetect
/dev/sda6             775         905     1052226   fd
 Linux raid autodetect
/dev/sda7             906        1036     1052226   fd
 Linux raid autodetect

Partition table entries are not in disk order

server2 seems to be working fine, but this is a weird
issue since I built the filesystems originally like
server1 under FC2, and the upgrade process has seemed
to make modifications which are undesirable. Notice
the warning at the bottom of the fdisk output?

How can I fix this?

Thanks.

Michael.
