The problem turned out to be that salvol only checks the boot partition 
at boot time.  So after the machine crashed, the second partition was
never checked.

1) I think that salvol should check all partitions in /etc/fstab.
2) "Invalid argument" is one of the dumbest messages I ever saw!

  > Hi, how do you change where swap space is on an 400t running DOMAIN/OS 10.3.5?
  1) You can't change where swap is located.  You can ADD to the main swap area,
     but you'll still swap to the '/' volume...
  3) To _add_ a swap area, check the '/etc/swap' command.  I think you want to
     NOT do this to a volume that has a file system, since the cautions appear
     to indicate that the O/S just starts using it, regardless of files.  Since
     all our disks have data on them, I decided not to play around with it....

I think the warning is left over from the Unix man page.  Domain/OS pages
from the free list, not from raw blocks on the device as most Unix systems
do.

The man pages for 'swap' and 'swapon' contradict each other.  'swap' claims
to be able to remove a "swap" device, but 'swapon' says you can't do this.
Maybe it means that you can't do it with 'swapon' but need to use 'swap'
instead.

Also, the program names are misnomers dating from the v7 days.  Back then
there was no paging, only swapping.  But 'swap' and 'swapon' have nothing to
do with swapping, which Domain/OS doesn't do.  Swapping is when you write
out a program's entire run-time context.  Paging is when you write out pages
from the program's address space that you aren't using at the moment.

Hello Apollites!

We've got a DNS3000 running as a token-ring/domain ring bridge under 10.3.
Before I try and find a card that Apollo supports (if any), is it possible
to add an ethernet card on top of that as a backup ethernet/token bridge for
our RS6000?

What cards are supported?  Am I better off buying a real bridge (at what 
cost)?

Thanks

Answers.  That's what I need.

Hello.
I am trying to start a news feed on my DN3550.  I have successfully 
compiled Cnews, but I get problems when compiling nntp (version 1.5.11).

I am trying to compile nntp to run as a news server (as opposed to a client).
I can compile the daemon as long as I don't define "syslog".  I get the 
following error on the compile when I *do* define "syslog":


  # cd server
  # make
  /bin/cc -O -c main.c

   (0226)                     openlog("nntpd", 0x01, );

  ******** Line 226 of "main.c": [Error #116]  Improper expression; ")"
  found.
  *** Exit 1

Well, if you look at the code, it doesn't take a rocket scientist to figure
out what's going on.  "Syslog" is supposed to be the last parameter and there
ain't no substitution going on there.  

I can't use the "fakesyslog" 'cause you have to define "syslog" to use that
too.  I have tried defining "bsd42" since it seemed like it might need that,
but I still get the same error.

I don't know "c" but experiences like this make me sorely tempted to learn...

My OS level is 10.3.5.4  and BSD is the primary environment on my Apollo.  I
installed the OS to be ansi "c" compliant.

*ANY* help would be appreciated. I am tired of reading comp.sys.apollo on a
VAX.

Please respond via Email.

Hi,

This program is very efficient to test the robustness of
an operating system . 

We are running the 8.05 version of HP-UX, is the 8.07 more

On the apollo it crash the PROCESS with an error message
but NOT the machine !

Hi there!

All machines have color monitors , 4-8Mb of RAM , hard disks, 
(4x180Mb, 760Mb, one diskless) and apollo token ring adapters.
All of them work fine but since our newer machines are all suns
we are phasing the apollos out because we can't justify the
adminstration overhead for two different platforms.

I can send you (or anyone else, or post if demand is high enough)
scripts that will close up your system fairly tightly, though others have 
sent me additions to my scripts that I have not implemented due
to lack of time and the impending death of Domain/OS (both at our

SR10.4, but won't find out until I have to install after invol.

file is not an object module or is not an executable on this machine type

I'm running Domain/OS 10.3.5.3 on a DN5500.  My master registry is on a
DN3550 and it has also been patched.  Actually all the slaves and the
master have been patched, but none of them can start the new rgyd.

The patch also replaces /lib/rgylib and as a result I have rebooted my
slave registry to involve the new lib file, however the result is the
same.  I cannot start the new rgyd.  The timestamps are the same as the
docs report.

The old /etc/rgyd (413K) is of type obj, the new /etc/rgyd (618K) is of

You can't attach a SCSI hard disk to anything but a DN2500 and the 9000/400
series.  The drivers are only there for tapes and related junk (including 
cd-rom, which looks like a disk but isn't).

I think this is in the FAQ, no longer distributed periodically or updated,

1) Maybe the DEC guy did a read-only export???  ('/etc/mount') should tell
   you whether it's mounted ro or rw.
2) Get NFS 2.3, or if you go to SR10.4, get 2.3.2.  NFS before 2.3 was bad.

Hello ,

we have a very strange problem running the bsd environment on an Apollo:
whenever we ceate a user account - using edrgy - the following situation
occurs:

- root can chown a file to belong to that user (normal)
- if the user creates a file in his (NFS-) mounted home directory (from a Sun), he is the owner (normal)
- if the user creates a file on a local (i.e. Apollo) directory, it belongs to 'none' (this is what I don't understand).

Is there anybody who can help me !!???

Many moons ago, I posted a message saying that ADUS/UK had asked me to
create a "technical tips" newsletter based on the information
available in comp.sys.apollo, as the majority of ADUS/UK members do
not have access to news.  Since then, my excuse has been that I've been
busy.  In reality I'm just hopelessly inefficient :-(

What I still need to know is whether people would, in general, object
to their pearls of wisdom being re-broadcast in this way.  I would
propose to re-write any items to make them fit in with the newsletter
style of the document, and I would also make it available freely via
comp.sys.apollo and/or anon ftp.  I would include a disclaimer
absolving "contributors" of responsibility, and, to avoid any chance
of legal problems, simply list the people who contributed to each
issue at the end of the issue, thereby removing association of names
with information.  Is this being too paranoid?  Over here we have a
horrible idea of the litigative excesses to which the american legal
system is prone...

Oh yes - the other thing is that I will only acknowledge someone with
their permission.

Any comments?  Does anyone intend to sue? (you're welcome to my overdraft).

Hmm...

I have this install script, that expects to find
/lib/libc.a or /usr/lib/libc.a  However, the only
libc, or clib I can find are in /lib, and don't
have the .a...  To top it all off, they are not ar
compatible.

What gives??  How do I get a libc.a for my DN3500
Domain/OS 10.3 - BSD4.3??

Please, anyone???
