Mounting USB DVD-ROM on connect

gravitek · 01-03-2007, 01:54 AM

Hi all,
I have an external usb dvd-rom plugged in to a desktop running 2.6.15-1.2054_FC5. The device is present under /dev/scd0. When inserted, linux seems to detect it ok, but then does nothing about making it available for use...

It works ok when I use the mount command, but can I get it to mount when I insert it in to the usb port, and on startup? Obviously if no media is present in the DVD-ROM the mount will fail so inserting the mount command somewhere on startup probably won't work...

Also, can I somehow get it to appear in in Konqueror under storage media? (system:/media)

Thanks in advance!

Google on automount.

In konqueror, enter "sysinfo:/"
That may give the udev or had daemons a kick in the pants. I think that it should be mounting as you want. A problem with a service not mounting or a shared library used by dbusd

You might want to post your /etc/fstab file.

If you enter: udevinfo -q env -p /sys/block/scd
Does it print out information about your drive?

Check if the udevd and dbus daemons are running.

The /etc/fstab entry created by Fedora may give a hint which helper program or service mounts CDs. What is the value of the type field (3rd field)?

ugh. apologies.

i added the line in to /etc/auto.misc below:
usbdvd -fstype=iso9660,ro,nosuid,nodev :/dev/scd0

then edited /etc/auto.master so it actually uses auto.etc with the line:
misc /etc/auto.misc --timeout=60

then /etc/rc.d/init.d/autofs -restart

even after a full system retart, it still isn't appearing in system:/media

any ideas?

'Protocol not supported' for sysinfo:/ in Konqueror

fstab file:
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0

/dev/VolGroup00/LogVol01 swap swap defaults 0 0
~

"no record for '/block/scd' in database" when typing
# udevinfo -q env -p /sys/block/scd

automount doesn't seem to be used to mount my internal cdrom drive anyway (which is working fine) becuase auto.misc was #'ed out in auto.master
