Err....no it doesn't.... it syncs the array as it installs, do a cntrl-alt-f3 when installing to bring a shell up then do a "watch cat /proc/mdstat"
and you can see it building the array as its installing, do a cntrl-alt-f7 to get back to the graphics screen.....
I did actually find what the problem was and this was it:
The SIS 965 chipset is not supported by the kernel so the IDE interfaces runs S-L-O-W-L-Y eg 1.7Mb/sec transfer rate to the disk, coupled with the RAID rebuilding in the background makes the install take about 6 hours if it can actually manage to complete, which it usually doesn't on this platform.
The solution: change the motherboard.... so I put a sempron socket A board in its place with a 3200+ CPU and it works fine....

The problem seems to arise when installing onto Mirrored disks, I have
noticed that from Centos 4 onwards it tries to rebuild the arrays as it
installs which slows the whole process right down across all platforms I
have tried it on.

<pre wrap="">In addition, the install process bails out at random times with random

Error reading DVD etc... now I have burnt several copies of the DVD,
tested them fully, tried installing from CD, even changed the hardware
to a twin Opteron system, changed the RAM changed this disks and tried
everything but it still seems really touch and go as to wether the
install will complete.
I haven't managed it yet on the Asus platform it took about 12 goes on
the opteron platform. Yet Centos 3.4 installs no problem.

That can be caused by bad cabling (length + quality) because kernel 2.6
is more sensible for standards. It can too help to deactivate DMA during
install with: linux ide=nodma.

That is a known issue and filed in bugzilla.redhat.com. Didn't happen
for my platform, grub was correctly installed, just not placed into both
RAID1 drive's MBRs.
