Subject: sudden file system inconsistency
Keywords: inconsistency
Date: 16 Apr 92 13:58:34 GMT
Organization: Delft University of Technology

I discovered the last 20 days during normal operation twice an inconsistency
on the same file system. That file system is about 600Mbyte and contains a part 
of our user home partitions. It resists on a secound Sun SMD disk (xy1) with
one Xylogics 450/451 controller. We use SunOS4.1.1 on a Sun4/280 which
is our main fileserver, with 32Mb core.  

On that disk we have two smaller partitons /export (140Mb) and /var (20Mbyte),
which has recently crashed (disappear completely) after interactive fsck ....

There is no reason for file system inconsistency, because there were no 
power interruptions or break downs.  After discovering, I fsck that 
filesystem and answers a lot of questions untill fsck is satisfied.

It srikes me that the file systems (on the same disk) is corrupted suddenly. 
(Few months ago on disk xy0 the root file system disappear (at night)
completely..). Some times the 4/280 reboots after panics... 

Sun.nl thinks there is a problem with disk xy1, but I doubt that, because 
there were no faulty xy1 disk messages in /var/admin. They suggested us 
to run newfs for that file system, but fsck has after repairing no problems 
with that partition. Other alternative of Sun Holland is to replace that 
disk, but I don't believe that the disk is the cause of the "inconsistency" 
problems ..

Are there any "other" suggestions to solve our "inconsistency" problem or
is replacing the disk the best solution?

Regards,

[I posted the following 5 days ago, but haven't seen it on my system yet,
so here goes one more attempt at posting it.  Apologies to anyone that
might see it twice.]

Is there a limit to the size of disks that can be used with a 386i.  Under
4.0.1 format aborts because of the response from the disk (I believe  when
trying to determine the capacity) with a Fujutsu 2266S.  Have had no (read
few) problems using a 380 Mb disk.  So what is the limit 760 Mb?

Can the problem be avoided by just using a format.dat to ignore (waste!) excess
capacity?

Please e-mail responses. If there are many me2's I will post summary.

P.S. mail to sun-386i-request@mailhost.acq.osd.mil bounced. Is that the correct

I'm trying to get an Apple LaserWriter II/NTX working on the serial
port of an SLC (SunOS 4.1.1), but there's apparently something I'm
missing.  I've:

o	Set the LaserWriter's dip switches as specified in the manual
	for PostScript via the serial interface at 9600 (1 up, 2 down,
	3 and 4 up);

o	Connected the serial cable to the printer and the SLC's port
	(I'm unclear, BTW, on using the combined ttya/ttyb port on the
	SLC--TFM suggests that an ordinary RS-232 cable plugged into
	it uses the "first" port));

o	Added the /etc/printcap entry shown below (which is copied from
	an SS2 with the same kind of printer--with modifications for
	the new printer name, etc):

Summary: Very handy for use with chroot.

>I am wondering, what is the main use of the loopback file system?
>Also any unusual uses of lofs.

I use the loopback file system to make /usr visible to locked-in accounts.

In /etc/passwd, it has:
  testsys1::2901:23:Test Environment:/home/testsys1:/usr/local/lib/xxlogin
  testsys2::2902:23:Test Environment:/home/testsys2:/usr/local/lib/xxlogin

The file /usr/local/lib/xxlogin is an executable binary, setuid root, that
invokes the following shell:
  #!/bin/csh -bf
  # Purpose: To do a "chroot" before letting a TEST user log in.
  if (! -d $HOME/usr/bin) mount -t lo -r /usr $HOME/usr
  echo "   Now connected to $HOME."
  echo -n "$USER "; exec /usr/etc/chroot $HOME /bin/login

When a person logs in as "testsys1", the following happens:
  1) The system-wide /usr directory is made visible as /home/testsys1/usr.
  2) The 'chroot' command makes /home/testsys1 be the root for 'login'
     and any child processes it creates.
  3) The user sees "testsys1 login:" and enters logname and password
     that is defined in /home/testsys1/etc/passwd.

Anyone logged in as "testsys2" will not be able to access any files stored
in the testsys1 area; due to the 'chroot', they can't see anything that is
not under the /home/testsys2 directory.

Summary: LOFS (and/or TFS) are very handy when using 'chroot'.

Subject: Paste screws up in OW3
Organization: D. P. Technology Corp.
Date: Sun, 12 Apr 1992 21:15:31 GMT

   I've been experiencing problems in OpenWindows where the Copy-Paste
screws up and gives me something else.  Example:

   using textedit, I will hilight a word or something and then I press the
   'Copy' key.
   
   If I now click a new position and press the Paste key now
   (in the same textedit window) it will copy the buffer correctly.
   
   Now if I go to my console window and press the paste key, I get something
   total different (I have no idea where it is getting this from).
   
I have especially experienced this kind of abnormal behavior when one of our
X-Terminals running olwm off this sun does a paste and sometimes when I copy
I get his 'copy buffer'.  Obviously this is a bug.  Is there a patch for this?

This problem also occured under OpenWindows-2 as well. (Sigh...)

Now if I can only figure out what I've gained by upgrading to OW3....

Thanks in advance,

We had a similar problem.  I had read the solution here several times, but
never believed it.  It was said to be caused by empty lines in the services
NIS map.  One day, I looked at the base file, and sure enough, somebody had
put empty lines there.  I modified yp/Makefile to strip empty lines, remade
services, and the problem went away.

Organization: EE Dept at UF

Very strange.  xrn 6.13, and now xrn 6.17, usually run nicely on one of
our Sun SS2's, but !really! whack the local disk for !minutes! when
doing almost anything when being run on an SLC.  If there's a lot of
newsgroup updating to be done in the .newsrc, xrn on the SLC might just
whack forever...

Has anyone seen this?
The SS2 and SLC are running the same executable and have the same
libraries -- in fact everything is the same, to the best of my
knowledge, except the SS2 has more RAM & swap.  But 16 Mb RAM on the SLC
!can't! be too little, can it??

We're running SunOS 4.1.1, and oh yeah, this test is done with an xrn
6.17 built against X11R5 libraries, or xrn 6.13 built against X11R4
libraries, running over/under the OpenWindows shipped with SunOS.

Thanks for your comments,

Thanks Joe (cool name :-) This suggestion works like a charm. Now, I just
alias the "sz" to "/usr/local/bin/sz -l 1024 \!*" and everything just works!

Hmmmm ... not being a serial communication expert (or even close), this

Thanks again. You have been a most helpful bunch.

And the misconceptions just keep on coming....

I have, in my hot little hands, err, umm, hot little CD-ROM drive, a
CD-ROM that came in a CD-ROM box with a lyric sheet, err, umm,
instruction booklet labelled "a release of Solaris(R) 1.0.1".

If I "cd" to the "/cdrom" directory atop which it's mounted, "cd" to the
"exec/sun4_sunos_4_1_2" subdirectory, and do "tar tvf usr | egrep ccom",
I get:

	r--r--r--  0/10   2905 Oct 23 10:10 1991 ./include/sys/ioccom.h
	r-xr-xr-x  0/10 344586 Oct 23 11:03 1991 ./lib/ccom

The latter file sure *looks* like the front end of the C compiler, but,
just to make sure, let's check whether the other bits of the compiler
are there:

	rwxrwxrwx  0/10      0 Oct 23 10:38 1991
		./bin/cc symbolic link to ../lib/compile
	rwxr-xr-x  3/3  98304 Oct 23 10:28 1991 ./lib/compile
	rwxr-xr-x  0/10  81920 Oct 23 11:03 1991 ./lib/cpp
	r-xr-xr-x  0/10 204800 Oct 23 11:04 1991 ./lib/iropt

	rwxr-xr-x  0/10 156161 Oct 23 11:04 1991 ./bin/ld

Sure looks to *me* as if all the pieces of the compiler (including the
assembler, and just for laughs including the linker as well) are there
on the CD-ROM for Solaris 1.0.1....

>I am now to familiar with that as we just

You've been had.  Go complain to Sun and get a new Solaris 1.0.1 CD-ROM
- after, of course, making sure you've properly installed Solaris 1.0.1
from that CD-ROM, so you don't look silly when you call Sun to complain
that the compiler wasn't on the CD-ROM and find that it *was* there....

The ``uutraf'' program posted to alt.sources 5-Nov-1989 by Greg Hackney,
news1@texbell.swbt.com, might be a good start.

It basically reads the HDB (I'm assuming you've SunOS4.1.* with HDB) databases
and provides a volume and time summary report for each host with time resolved
to tenths of an hour (which was adequate for my purposes reconciling my bills).

There were two patches posted by the author, and I hacked on my copy a bit
to improve its output formatting (for my applications).

If you cannot find alt.sources archives (try UUNET), perhaps the author can
be persuaded to repost.

Setup: DECstation as YP master, Sun IPC (SunOS 4.1.2) as YP

can't use the -B option discussed in the manual since the YP master
is not running SunOS. A similar setup seems to work with a bunch
of Suns and a DECstation YP master (single server, no slave server),
but nobody around here seems to know or remember why it works.

What do I need to do?

Yes!  I couldn't figure it out.  Some things just seemed to have stoped
working.  I tried to do some debugging on uucp, edited the contab,
but then things seemed to start working again, at least for uucp.  I
ended up rebooting today because it was just too weird.  I figured
that loading the system fresh may solve the problems.  I never put it
together with daylight savings, but that must have been it.

You are right. Broken since 4.1.1. If you look at the manpage you will
notice that some syntax changes have been made since 4.0.3. Presumably
the programmer doing this wasn't too good. I reported this bug a year
ago to Sun, my local Sun-support centre fixed it for me(good work),
and come 4.1.2 it was still broken.

They also broke the mount -a dependency tree building in 4.1.1. This
has also not been fixed in 4.1.2. But wait... Solaris 2.0 is coming
and then all will be fine!

Sure,

I don't know how much help this is but we have one hooked into a 4/280
and by the looks of it it is connected by a standard external SCSI.  That's
the only cable running to the Sun.  Ours happens to be daisy chained along
with an external SCSI disk as well.  

Be sure /dev/sr0 is in your kernel as well, otherwise it won't recognize it.

I can't say too much more without knowing what you have tried.
