[comp.unix.aux] A/UX trouble

bwild@foxi.uka.de (Bernd Wild) (11/16/90)

We purchased an MacIIfx with 16Mb some weeks ago to install A/UX on
it, but...
After exchange of all memory SIMMs and the complete mother/board
we are still unable to get A/UX running with NFS and YP. During
the boot process when A/UX checks its file system and install the 
processes it gives us only the notice "panic: ialloc: dup alloc"
after one-third of the progress bar. What's that????
It's impossible to restart the Mac even after pressing the reset
button! Only switch-off/switch-on helps!
Any ideas?
Bernd.

It's telling you that it has discovered a single inode allocated to two
different files. Try running fsck on the guilty party. But that should be
done automatically on boot when it discovers that the disk is "dirty" so
there may be deeper problems. You didn't my any chance do something werid
with dp, did you? (Though I'm not sure that even that could cause this 
message.)

It could also mean just about _anything_ if your system is really messed up.
I'd suggest reformatting and repartitioning the disk from scratch, if
nobody else has any better ideas.

	It's telling you that it has discovered a single inode
	allocated to two different files. Try running fsck on the
	guilty party.

Good advice.

	I'd suggest reformatting and repartitioning the disk from
	scratch, if nobody else has any better ideas.

Bad advice, unless you like wasting time.  After you launch the boot
process from MacOS, click the Cancel button ... this will bring you up
single user.  Run fsck from there, and then reboot.

Huh? Is this not what I first said? "Try running fsck..."
The second paragraph was fallback- that is, if fsck didn't do the trick.
