I just cannot keep the system from resyncing on every boot.  I've
gotten to the point that I'm thinking that I may have been root'ed and
the boot flash of the drives has been reflashed...  Ok, that is
reaching for an answer, I know.  This is time to ask for help.  help!

If you boot knoppix and manually assemble the array does it assemble 
cleanly
or does it need a resync as well?

Well, I used my last CD-R on the WD Data Lifeguard.  But, I think I 
know what you are driving at.  Booting Mandriva 2009 into Rescue mode, 
then choosing "Mount your partitions under mnt" does cleanly start the 
array.

Following that further, I booted off /dev/sda1 (where my small 
Mandriva system is currently installed), then I disabled the mdadm 
service in /etc/init.d/.  I then waited for the system to do the 
resync and rebooted the system. Then logged into the system.

Just for grins, could you post the partition table for each disk? Maybe 
just the output of "fdisk -l" to show everything? I always worry when 
using drives of "almost" the same size.

Sure, identical tables for all six drives:
Disk /dev/sda: 320.0 GB, 320071851520 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x733f1de9

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2433    19543041   fd  Linux raid 
autodetect
/dev/sda2            2434        2677     1959930   82  Linux swap / Solaris
/dev/sda3            2678       38900   290961247+   5  Extended
/dev/sda5            2678       38900   290961216   fd  Linux raid

Configuration is three RAID1 for '/', '/tmp' and '/var'.   RAID10 for 
/home as the larger array.
