Error mounting CDROM

[dictum9]

This is on 11iv2. I keep getting this error even after rebooting the machine. Any idea what's going on?


# /usr/sbin/mount -F cdfs -o rr /dev/dsk/c0t0d0 /SD_CDROM
mount: /dev/dsk/c0t0d0 on /SD_CDROM : Device busy

[Steven E. Protter]

Shalom,

There is a process open on it.

fuser -u /SD_CDROM

-uk should kill it and permit mounting.

HI,

You tried run fuser in directory for looking for any process?

# fuser /SD_CDROM

[Torsten.]

Please check your /etc/fstab file. Perhaps there is an entry to mount the device and the system will mount the drive while booting. Check output of mount also.

I had this problem on another machine, and what you said helped there, but not here. I think it's a different issue. Hardware related maybe? Ioscan -funC disk reads just fine.

# fuser -u /SD_CDROM
/SD_CDROM:

# fuser -ku /SD_CDROM
/SD_CDROM:

# /usr/sbin/mount /dev/dsk/c0t0d0 /SD_CDROM/
mount: /dev/dsk/c0t0d0 on /SD_CDROM : Device busy

Nothing unusual in either /etc/fstab file or mount output.

I wonder if I should reseat the CDROM drive, I cannot think of any other issues. I rebooted the machine and still getting the same thing. Something is wrong.

cd /
fuser -cu /SD_CDROM
fuser -ku /SD_CDROM
umount /SD_CDROM
mount /dev/dsk/c0t0d0 /SD_CDROM

[dictum9]

# fuser -cu /SD_CDROM
/SD_CDROM: fuser: could not find file system mounted at /SD_CDROM.
# fuser -ku /SD_CDROM
/SD_CDROM:

# umount /SD_CDROM
umount: cannot find /SD_CDROM in /etc/mnttab
cannot unmount /SD_CDROM
# mount /dev/dsk/c0t0d0 /SD_CDROM
mount: /dev/dsk/c0t0d0 on /SD_CDROM : Device busy

Hello,

Just a thought: You can try with rockridge extensions,

could you post the output of

# ioscan -fnCdisk

Hi,

do an ioscan and
what does 'bdf' says?

Volkmar

[V. Nyga]

There should be a space between C and disk:
ioscan -fnC disk
(Sorry RJ) :-)

But it seems like you use the wrong device file.
So ioscan and bdf should show more.

I am using /dev/dsk/c0t0d0 device to mount onto /SD_CDROM


# ioscan -fnC disk

Hi again,

create a new directory /SD_CDROM1 or just /test and try to mount to this directory.
If this doesn't work, then I think your CDROM is gone.

[dictum9]

Already tried that to no avail.

[James A. Donovan]

Will the cd mount if you leave of the "-o rr" part of your command?

i.e.,

# usr/sbin/mount -F cdfs /dev/dsk/c0t0d0 /SD_CDROM

[Sandman!]

Hi...what's is the output of

# diskinfo -v /dev/rdsk/c0t0d0

cheers!

[Carlos Roberto Schimidt]

/SD_CDROM is configured for automount?

If you can mount cd on other directory, i think you have configured automount for your cd.

If you run "ls -l /SD_CDROM" have any output?

TEAC cdrom, there is a patch for this cdrom player(PHKL_27224)

Sorry just read your initial post 11iV2. Try to recreate the device files for your cdrom.

/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0
# mv /dev/dsk/c0t0d0 /tmp/
# mv /dev/rdsk/c0t0d0 /tmp/
# insf -e

# ioscan -fnCdisk
# mkdir /cdrom
# mount -F cdfs -o rr /dev/dsk/cxtydz /cdrom

Robert-Jan
