Having experienced the issues with 10.3 vs. 10.4 ADU RAID differences
first hand when a staff "tech" hosed a school server trying a
recovery the same way that Christopher did.
I just remastered three K-6 servers requiring Mac Manager for OS 9
clients, so 10.3 was the required base start. That being the forced
hand, I installed 10.3 Server on an external FW and only after
upgrading to 10.4 to preserve the MM capability, did I used
SuperDuper to move the FW install to the RAID created under 10.4.
Experience with trying to upgrade a 10.3 created RAID has, in my
experience, been an iffy transition.
In Christopher's defense, I recall having to dig pretty deep to find
clues about RAID v1 to v2 promotion at the time (Nov 2005). It isn't
clearly documented... but in all cases where critical data is on the
line and a bunch of users are out for blood, proceeding cautiously is
most important.
With a degraded 10.3 RAID, I recommend backing up the surviving drive
externally and then recreating a fresh RAID mirror under 10.4.
