Unfortunately, I didn't get any concrete answers to this one; I guess I
do a good job of playing "stump the experts" :-)
Many thanks to

- David Wolfskill
- Arthur Darren Dunham

for their suggestions. I haven't yet been able to look at a listing on
tape compared to a listing of the disk itself to compare inode numbers,
but most folks suggested that 2G is the limit and that ufsduump will
pick up inodes pretty much in order. I have, in the past, personally
dumped over 20 (twenty) G with ufsdump with no problem, though...
Because we're already using Legato here for another set of machines and
they have no problem dumping large metadevices, we're going to set up
these servers as Legato clients as well (sorry, Rich ;-) and send them
to our 1T DLT stacker (a nice added bonus!). Nonetheless, we sure would
like to know why the problem exists, because we will almost certainly
want to ufsdump the Legato server and its database disk (which will
probably be a large metadevice)...
:-D
