Help with NeXT network needed!
Situation
10 NeXTs, two with 660MB Hard Disks, NeXT-only network.
System 1: 'gauss' set up as configuration server, and boot server.
System 2: 'euler' set up a clone configuration server, and houses the
'/Users' directory, home of the network-wide user accounters.
Problem: If I add a system to boot over the network it works fine if
I tell netinfo to boot it off of gauss. If I tell netinfo to boot it from
euler, it loads the kernel OK, but panics with the famous error 13 when it
tries to mount root.
Clues:
If I boot euler from the monitor, it exports /Users, and then LATER does an
exportfs to export / and /clients, which are essential to booting
systems over the network. This exportfs FAILS for / because /Users is
already exported, which is a NO-NO apparently.
How would you set up network-wide accounts with ONE server, then?
Wouldn't you see the same problem? As Phil Donahue says, 'help me out
here.'

You ARE correct that this is a no-no. Then look into /etc/xtab to see what has in fact been exported. How we do it: "/etc/exports": / -root=tompkins <the config server> /clients/danby -access=danby,root=danby /clients/newfield -access-newfield,root=newfield <the clients which are DISKLESS BTW> NOTE: exporting "/" still exports Users which is the end-goal here. >Problem: If I add a system to boot over the network it works fine if >I tell netinfo to boot it off of gauss.

Make sure exports has been redone as above, then make the entires for the bootparams in NetManager (don't niload from /etc/bootparams, there's a bug in NetInfo that says you have to make a change, then save it back to network.nidb before it'll take....they've NOT fixed this in 1.0, but acknowledged it!). In our situation. tompkins is the config server and 4 other 660 machines are client servers. MACH comes from tompkins only as cloning the nidb didn't help that bottle-neck, but the client-trees come from the other 4 servers which all have their exports done as above. Honest, it works. If you still need help drop me mail or call. Roger Jagoda FQOJ@CORNELLA.CIT.CORNELL.EDU (607) 255-8960
