CDRW enable as scsi

lilsirecho · 2003-11-27 07:27:59

My scanbus indicates the cdrw is scsi bus 0 and I assume that means it is id sda0.

The following is my Fstab:
/dev/cdroms/cdrom0 /mnt/cd iso9660 ro,owner,noauto,unhide 0 0
/dev/cdroms/cdrom0 /mnt/dvd udf ro,owner,noauto,unhide 0 0
/dev/floppy/0 /mnt/fl vfat owner,noauto,unhide 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
tmpfs /tmp tmpfs size=2G,nr_inodes=10k 0 0

/dev/discs/disc0/part3 / ext3 defaults 0 1
/dev/discs/disc0/part1 /boot ext2 defaults 0 1
/dev/discs/disc0/part2 swap swap defaults 0 0
/dev/discs/disc1/part1 /mnt/fat vfat defaults 1 0
/dev/discs/disc2/part1 /mnt/fat1 vfat defaults 1 0
/dev/sda1 /mnt/fat2 vfat defaults 0 0
/dev/sda0 /mnt/cdrw auto rw,owner,noauto 0 0

When I try to mount the drive , i get the error...
mount: special device sda0 does not exist.....

What is the solution to this prob?

$ modprobe ide-scsi
$ modprobe sr_mod

Change /dev/sda0 to /dev/cdroms/cdrom0 in your fstab. There's no sda0 device .

Hello again!

Followed the post instructions and did get a new listing for the cdrw .....

I receive an error:
mount: wrong file sytem bad option or too many filesytemms....

Fstab follows:

/dev/cdroms/cdrom0 /mnt/cd iso9660 ro,owner,noauto,unhide 0 0
/dev/cdroms/cdrom0 /mnt/dvd udf ro,owner,noauto,unhide 0 0
/dev/floppy/0 /mnt/fl vfat owner,noauto,unhide 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
tmpfs /tmp tmpfs size=2G,nr_inodes=10k 0 0

/dev/discs/disc0/part3 / ext3 defaults 0 1
/dev/discs/disc0/part1 /boot ext2 defaults 0 1
/dev/discs/disc0/part2 swap swap defaults 0 0
/dev/discs/disc1/part1 /mnt/fat vfat defaults 1 0
/dev/discs/disc2/part1 /mnt/fat1 vfat defaults 1 0
/dev/sda1 /mnt/fat2 vfat defaults 0 0
/dev/cdroms/cdrom0 /mnt/cdrw iso9660 ro,owner,noauto 0 0
Is there any further error?

Hello to you too .
Check if your cdrw is your first or second cd-rom drive & change /dev/cdroms/cdromX accordingly...

Added info...

In scanbus, I now have dropped the entry for scsibus 1 and cannot mount the USB drive on sda1.
Error.../dev/sda1 does not exist.....

Hello on turkey day! Enjoyed a family feast here today and am recovering from the stuffed pig syndrome!!!

Entered cdrom1 for the cdrw and am now able to mount it.

So I have something to thank you for...and another thing to attempt a solution for...I have lost the mount of the external USB hdd which appeared on scsi bus 1.
This happened after setting up for the cdrw with modprobe.

The scanbus at this time shows the cdrw on scsi bus 0. The error message says sda1 does not exist.

zen_guerrilla · 2003-11-28 09:51:45

sr_mod : is the module for scsi cd-roms
sd_mod: the same but for hdds

You need to have "ehci-hcd usb-storage sd_mod ide-scsi sr_mod" in your MODULES list in /etc/rc.conf.
Then a simple "cdrecord -scanbus" should show you both your cdrw & your usb hdd.
Happy recovering btw .

lilsirecho · 2003-11-28 18:14:23

Hello again zen:

I was able to re-establish the sda1 in scanbus and have mounted it OK. Don't know why it got dropped because I obviously had the entries you outlined or it wouldn't have worked initially.
I now have a new problem due to a deletion of /etc/rc.conf file while cleaning up after changes and cannot boot up or shutdown. In boot up there is no host ID so can't start up. In reboot, it hangs due to no shutdown sequence.

How should I proceed?

Guest · 2003-12-03 01:36:13

Hmm it appears as if I'm running into the same wall - though this does not fix it.

I have the ide-scsi module loading (read in the MODULES array) on boot, and the append="hcd=ide-scsi" and everything works fine and dandy.

cdrecord -scanbus reports everything nice and neat. The problem is that I can't seem to mount a cd (or at least the music cds I've tried).

One thing I keep thinking about is if /dev/cdroms/cdrom0 should be linked to /dev/scsi/host0/bus0/target0/lun0/cd (as it is now) or /dev/sr0... (on a side note I also have a link to the whole /dev/scsi... chain in /dev/sr/c0b0t0u0 - that link name seems a bit kooky to me).

ok logged in now

there is one certain upgrade out there that removes your entries from /mnt if the directories that the mountable devices, such as floppy drives and cdrom drives, do not point to in fstab do not exist then you won't be able to mount anything in them.

i have run into this on occasion. not sure which package cleans up /mnt.

phrakture · 2003-12-03 01:49:21

hmmm I didn't clarify this - the problem I am having is mounting CDs

I get the "mount: wrong fs type, bad option, bad superblock on [...], or too many mounted file systems" error from mount

the [...] above is either of:
[x] /dev/sr0
[x] /dev/scsi/host0/bus0/target0/lun0/cd

tried both to no success... burner is a Lite-On something or other - but that shouldn't be important.

sarah31 · 2003-12-03 01:51:36

audio cds ? dvs? neither can/need to be mounted

phrakture · 2003-12-03 03:57:16

hrmmmm

phrakture · 2003-12-03 04:16:04

I apologize for being retarted... xmms gave me crap about being unable to mount the cd but I found out that was using /dev/cdrom. I retraced my steps after you mentioned that....
Thanks
