Subject: Standalone I/O system problems and a bug (#307)
Index: sys/pdpstand/* 2.11BSD
Description:
1. The standalone I/O system can not handle unlabeled disks as
sequential tape-like devices.
2. Multivolume dump sets (e.g. root filesystem dump on several
RX33 or RX50 diskettes) do not work. Standalone 'restor' does not
receive the 0 return value signifying EOF (end of media) when reading
disk volumes.
Repeat-By:
Create a multivolume dump of a 'generic' root filesystem to RX33
(or RX50, but you will need a lot more of them). An RX33 looks like
a 70 foot tape to 'dump'
dump 0sf 70 /dev/rra9a /dev/rra8a
is how I dumped the root partition of ra8 (an RD54) to ra9 (a RX33).
The 'generic' root filesystem fits on 4 floppies.
1. Boot from a standalone tape or floppy. Load 'restor'. Specify
'ra(1,0)' in response to the "Tape?" prompt.
Note that the 'disklabel is missing or corrupt' message appears
and is interpreted as a fatal error causing the 'open' to fail.
2. You will not be able to reproduce the second problem as long as
the error above is 'fatal'. I stumbled across the second problem
after fixing the first. 'restor' reads the input media until
EOF (0) is returned. However, the disk drivers in the standalone
system had no "EOF" detection logic - the first error that would
be encountered would be when the 'read' went off the end of the
disk and that was considered to be a "hard"/"fatal" error.
Fix:
The initial 'fix' (for the first problem) was 3 lines long (excluding
comments) in pdpstand/label.c.
You guessed it - things snowballed downhill from there.
Fixing the second problem was considerably more complex. The three
drivers which support disklabels (RA, RL, XP) needed to have inserted
a check for a read/write being off the end of a partition/drive.
The 'end of volume' check was placed in a routine that all drivers
can use (in conf.c) although at the present time only 3 of the disk
drivers call it. If an I/O request is exactly at the end of the
partition/volume then EOF (0) is returned. If the request is past
the end of the volume then an error (-1) is returned. Partial requests
are now handled correctly but nothing in the standalone environment
performs them.
During the debugging and testing of the changes it was noticed that
the device names printed in error messages were quite inconsistent.
Sometimes a device/partition name would be printed as "xp(0,0,0)"
while other times it would appear as "xp0,0a" or "rl0,0,0". A
common format was selected and all (except for a couple very rare
messages in the TMSCP driver) error messages were changed to use
the "dev(ctlr,unit,part)" format for a device name.
To install this fix cut where indicated and save to a file (/tmp/307).
Then:
patch -p0 < /tmp/307
cd /sys/pdpstand
make clean
make
cp boot /boot
If you keep bootable tapes/floppies around (a *very* good idea)
then now would be an excellent time to recreate them using 'maketape':
./maketape /dev/nrmt0 maketape.data
dump 0f /dev/rmt0 /
will create a bootable tape with a dump of the root filesystem on it.
