I'm in a dilley of a pickle here.  In my great ignorance I
accidentally corrupted my /dev/rst0 file by cp'ing another file to it.
(dumb, I know)  Of course all my backups are on tape and now, when I
try to access the drive I get an I/O error.  Not too surprising I
suppose.  I've got a good copy of my filesystem on tape so if I could
manage to run a restore session I think I could replace the file.  How
do I fix this?

What unix is this?  on most free unices you just

cd /dev
./MAKEDEV all

as root to rebuild all devices...

mknod is the command to create devicefiles. What parameters you need
is a function of what OS and version you use.

I'm running OpenBSD 3.2 (i386).  Will

/dev/MAKEDEV all

screw up any device files for the rest of the system?  Can I just run

/dev/MAKEDEV st0

to rebuild the file I need?

That should be ok.

Yes. Thats the best solution

Just tried it and it ran OK but I still get

mt: /dev/rst0: Input/output error

Tried running /dev/MAKEDEV rst0 but it tells me

rst0: unknown device

What am I missing?

Dunno. What does ls -l /dev/st* show ?

"Input/output error" occurs when tapedrives are "not ready" or simular.

Also do a dmesg and search for 'st'

The command 'mt status' could give "interesting" output.

I don't know about BSD, but in Linux, even though a /dev/whatever
exists, you might need to load a module for some devices.  lsmod lists
the modules that are currently loaded.
