We have had a problem where the major and minor device numbers of
various devices have been changing to 0 (a scary bug, since it
modifying the file system). We set up a program, and a list of
devices for it to watch.
Maybe if a bunch of us can report the symptoms to DEC, then they will
be able to figure something out faster. Below is a shar file with the
programs we have set up. If you have problems with them, please let
me know.

#! /bin/sh
# This is a shell archive, meaning:
# 1. Remove everything above the #! /bin/sh line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create:
# ./-README
# ./DEVICES
# ./DEVICES.README

# ./checkdev.8
# ./checkdev.c
# ./dev

if test -f './-README'

echo shar: "will not over-write existing file './-README'"
else
cat << \SHAR_EOF > './-README'
DEVICES: The list of devices to be checked at columbia
DEVICES.README: description of the DEVICES file. See checkdev.8
OURDEVS: Shell script run out of crontab to validate and correct device
errors, and to notify us of them.
dev: A shell script for looking at devices with a specific
major/minor number
showdev.c: program which just prints device names for a specified major/
minor number
checkdev.c: program to do device error detection and correction.
showdev.8: man page for showdev
checkdev.8: man page for checkdev.
We have things configured to run showdev/checkdev out of /etc, and OURDEV
out of /dev. Also the file DEVICES resides in /dev. Some minor changes would
be needed to move those around (ie, absolute filename in shell scripts).

.SH NAME
checkdev \- check consistency of system special files
.SH SYNTAX
.B checkdev
[-iq -f devfile -d devdir]
.SH DESCRIPTION
Verifies the devices in the
.i devdir
directory which are specified in the
.i devfile
file for consistency. Checks the mode, owner, group, major/minor
device numbers, and block/character "specialness" of the files.
Creates missing files, and "fixes" files which are incorrect.
.SH OPTIONS
.TP
.B -i
Run in interactive mode. This turns off quiet mode.
.TP
.B -q
Run quietly. Don't generate information about actions.
.TP
.B -f filename
read filename for the list of known devices.
.TP
.B -d directory
create/check the devices in the specified directory.
.SH FILES
Reads in a file for the listing of known devices. This file is of the
format:
.sp
special mode owner group major minor name critical
.sp
c/b 777 root wheel 3 2 null y
.TP
.I special
character/block (c/b) type of special file.
.TP
.I mode
mode of the device (or'ed with 07777).
.TP
.I owner
user who should own the device.
.TP
.I group
group which should own the device.
.TP
.I major
major device number.
.TP
.I minor
minor device number.
.TP
.I name
device name.
.TP
.I critical
critical nature of errors. if 'y', than fix any errors, otherwise,
only fix critical errors (leave mode, owner, group alone).
.SH SEE ALSO
mknod(1), stat(2), showdev(8).
