Another cd-burner thread (kinda long)

[flashingcurser]

Yes I am following the PET lets start basic info: cd/dvd on hda and cd/writer on hdc. Slackware 8.1 (with, correct me if I'm wrong, scsi general (sg) built into the kernel)

LILO:

# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/hde8
label = Slackware
read-only
append="hda=ide-scsi hdc=ide-scsi"
# Linux bootable partition config ends

On boot up:

scsi0: scsi host adapter emulation for IDE ATAPI devices
Vendor: NEC Model: DV-5800B Rev: G9A3 Type: cdrom ANSI scsi revision: 02
Vendor: PHILIPS Model: PCRW804 Rev: 2.0 Type: cdrom ANSI scsi revision: 02
Attached scsi CDROM sr0 at scsi0, channel 0, id 0, lun0
Attached scsi CDROM sr1 at scsi0, channel 0, id 1, lun0
sr0: scsi3_mmc drive: 20x/48x cd/rw xa/form2 cdda tray
Uniform CD-ROM driver revision: 3.12
sr1: scsi3_mmc drive: 32x/32x writer xa/form2 cdda tray

fstab:

/dev/hde9 swap swap defaults 0 0
/dev/hde8 / reiserfs defaults 1 1
/dev/hde10 /home reiserfs defaults 1 2
/dev/hde7 /fat32-mp3 vfat defaults 1 0
/dev/cdrom1 /mnt/cdrom1 iso9660 noauto,owner,ro,defaults,users 0 0
/dev/cdrom2 /mnt/cdrom2 iso9660 noauto,owner,ro,defaults,users 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0

I have also added modprobe ide-scsi and modprobe sg to the rc.local, the modprobe gs gives and error I believe thats because it in the Kernel not a module.
Also, I've tried symbolic links to scd0 and scs1, sr0 and sr1, hda and hdc, sda and sdc. All with the same result, the mount point doesnt exist.

Sorry about the cut'n'paste happy crap.

Any thoughts guys? All will be welcome, thanks

I used to get the same error on my system. I edited /ext/fstab to use /dev/sr0 instead of /dev/cdrom, and it fixed it for me.

[flashingcurser]

Wow that was fast!

So just ditch the ln -s and run with sr0, cool

Thanks

[flashingcurser]

Dang, no go. Any other ideas?

Dude, are you getting anything out of cdrecord -- look at this:

sudo cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling
cdrecord: No such file or directory. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root


This is my work's workstation, so I dont have a CDR drive attatched. So if you get this output, the SCSI emulation and generic driver arent working correctly. Chances are that you need to pass to the kernel that you want /dev/hdc (or whatever) to be using the SCSI not IDE driver. This was always my #1 test to see if it is getting the kernel config is configured correctly.

HTH

Try checking if /mnt/cdrom1 and /mnt/cdrom2 exist. If they don't, then do a mkdir /mnt/cdrom1 and mkdir /mnt/cdrom2
Try then mounting them manually. mount /dev/sr0 -t iso9660 -r /mnt/cdrom1

Schotty: I get something like this:

Well I guess that means that it loaded ok

Thanks, that ones goin' into the notebook.

[flashingcurser]

Trickster that was it! (I feel really stupid now ;D) It was probably working all along I just didnt have the mount point /mnt/cdrom1 for fstab to find.

Thank you greatly

[flashingcurser]

Doh... thats what I get for opening my big mouth.

Now I get a Kernel panic when I:
mount /dev/sr1 -t iso9660 -r /mnt/cdrom2

I'll copy down the error message if it does anyone any good, I'll do it again tonight.

Thanks

hello,
so the PET did not help 'eh. well please let me know where it was wrong or not helpful.

also what is the -r argument for ? Have you loaded modules sg and ide-scsi ?

BTW - what kernel are ya using?
