CDRECORD *shmget failed*

CDRECORD *shmget failed*

Post by root » Thu, 06 Apr 2000 04:00:00



Ok, I am new at this stuff, but I am fairly experienced when it comes to
the pc. Now, If I do a fresh install of Linux 6.2 I can get the writer
to work without a fail.  When i compile a new kernel to impliment my
Promise Ultra66 everything seems to go well, I can even see my HP 8200i.
IF I try to, lets say blank a CD-RW (which i have done with a fresh
install successfully) I get this error


Cdrecord 1.8 (i686-pc-linux-gnu) Copyright (C) 1995-2000 J?rg Schilling
cdrecord: Invalid argument. shmget failed

Now I did a man on shmget, and I am assumeing by what i was reading that
it has to do with a memorey allocation problem.  Is there something I am
forgetting to compile into the kernel? Has anyone else had this
problem.. and by chance do tehy know how to fix it? I have been
searching for the answer for awhile, even redid the system..

here is "cdrecord -scanbus"

ahhh found the problem!!!

You have to add this mount in your fstab.

none   /var/shm    shm    exec,dev,suid,rw  0 0

(just incase you run into the same problem!!! Cheers! :)

cdrecord 18 is bet and kernel  2.3.XX are beta... so they may have bug :-(

cdrecord 1.8 release are stabe with kernel 2.2.13.
I use the SG2 driver from Schilling and it works fine.

PS : be careful of what u do when u are root

[snip]

For kernel 2.3.XX, you need to put another line in your /etc/fstab if you
wish to use cdrecord.  That line is like so:

none            /var/shm         shm     exec,dev,suid,rw 0 0

Shared memory is now apparently a filesystem.  (Seems weird to me, but I
guess the kernel developers had a reason.)  The "suid,rw" bits worry me,
but since the man page for mount(8) hasn't really been updated yet, I have
no idea exactly what's going on.[0]  I did that and cdrecord's been
working well with 2.3.99-pre3.  

[0] I know, but reading kernel code makes my head spin.  One of these
days....

1. cdrecord: Invalid argument. shmget failed


I seem to remember getting this. It's trying to grab a chunk of shared
memory but the system won't give it. If you hack the code to ask for a
smaller chunk it works. I think there may be a command line argument
to do it without recompiling but I forget what it was. Sorry I can't
be more specific but I'm at work and my linux box is at home. Try
grepping the code for shmget.
