PostPosted: Fri Apr 26, 2013 1:22 am    Post subject: CD-Roms don't mount Reply with quote

I am running system 3.7.10-gentoo-r1 on an amd64 system. I just received a CD with jpg files on it and they wouldn't mount and the /mnt and /media directories don't show any volumes.

I dual boot with kubuntu so I booted into that system and the CD mounted just fine on "/media/New Volume".

I'm puzzled by this because in other times, CD's mounted just fine.

emerge --info follows:

Some additional information:

I rebooted with the CD in the drive and it opened when I booted up and logged into KDE. I used the KDE device notifier to remove the CD successfully.

I was not able to get the drive door open until I rebooted. When I did reboot, the drive door opened but the system did not recognize the drive.

Flash drives do mount successfully. My Passport USB drive also opens correctly.

try this:
Code:

# mkdir /mnt/cdrom
# mount iso9660 /dev/cdrom /mnt/cdrom

if it helps just config you cdrom line of /etc/fstab in this way:
Code:

/dev/cdrom              /mnt/cdrom      iso9660         noauto,ro,user  0 0

Mounting it manually works!

It seems as if the system is happier if, instead of "iso5660", it is mounted with "auto" in fstab.

I have to be root to mount the DVD. It does not unmount automatically and I have to be root.

I tried changing the ownership of /dev/cdrom. That didn't work. Nor could I change the ownership of /mnt/cdrom, /dev/sr0 is owned by root:cdrom.


    c@bopper /etc/portage $ ls -al /dev/cdrom
    lrwxrwxrwx 1 root root 3 May 4 15:14 /dev/cdrom -> sr0
    jc@bopper /etc/portage $ ls -al /dev/sr0
    brw-rw----+ 1 root cdrom 11, 0 May 4 15:14 /dev/sr0
    jc@bopper /etc/portage $ ls -al /mnt/cdrom
    total 10
    dr-xr-xr-x 4 nobody nobody 136 Oct 3 2003 .
    drwxrwxrwx 4 root root 4096 Nov 17 2010 ..
    drwxrwxrwx 2 nobody nobody 40 Oct 3 2003 AUDIO_TS
    dr-xr-xr-x 2 nobody nobody 1132 Oct 3 2003 VIDEO_TS


So I am still puzzled why it doesn't mount correctly after doing so for so long...

I used kuser to add it in and it worked. My username is in the file already.

Just out of curiosity, given the appended '+', what did 'getfacl' print on the device node ?
Cause it looks like those group changes should have been unnecessary.

Also, VIDEO_TS/AUDIO_TS would suggest it's a movie DVD, so the filesystem is invalid anyway.

Any thoughts on what to do to make CD's automount like they are supposed to?

"Like they are supposed to"? What software do you have installed to handle automatic mounting of CDs?

You don't appear to actually have any problem at all mounting CDs, which may be why you are having trouble attracting interest in replying to the thread. Your issue seems to be related to automatically mounting CDs.

Output of getfacl shows, that those moves on groups were most likely unnecessary - the permissions were already correct.

Next step to test would be udisks.
Depending on what the KDE component was built against, check if 'udisks -mount'/'udisksctl mount' is able to mount the disc with a filesystem.

udisks worked:


    bopper LibreCAD # udisks --mount /dev/sr0
    Mounted /org/freedesktop/UDisks/devices/sr0 at /mnt/cdrom


udisksctl worked:


    bopper LibreCAD # udisksctl mount --block-device /dev/sr0
    Mounted /dev/sr0 at /mnt/cdrom.

What are the values in /sys/module/block/parameters/events_dfl_poll_msecs and /sys/block/sr0/events_poll_msecs ?

Also, that question about " What software do you have installed to handle automatic mounting of CDs" might be valid.
Your posts suggest you're using KDE, but be more specific on how complete it is.

    # cat /sys/module/block/parameters/events_dfl_poll_msecs
    0



    cat /sys/block/sr0/events_poll_msecs
    -1


I should have been more precise:

When I insert a DVD or CD in the player, it does not show up as a file system in /mnt/cdrom unless I explicitly mount it. It seems to be inconsistent whether I can see files if "ls /dev/cdrom" at that time. Sometimes I have to use the KDE device notifier and press the Open it with the File Manager "button" and then it will show the files.

My experience is that the mount used to happen automatically.

I was using the KDE Device Notifier that lets you perform various actions when a CD/DVD is inserted. It seems as if once it detects that the DVD has been mounted, the notifier opens to give you a selection of actions that can be performed with the device. I was using that to show that the system had recognized the presence of the CD/DVD.

That's wrong. Did you mess up your udev rules ?
It should be set to a sane (>0) value - udev, if unset, sets it to 2000 (at least udev 200 still did).

Can I just put the value somewhere, or is there a defaults file somewhere?

I haven't touched any udev settings, except that there was a fleeting "equery news" article and a follow-up article about configuring udev. It said something about old versions of the 70* rules causing trouble. I experimented with renaming these files out of /etc/udev and found that was the only one that "70-persistent-net.rules" that could be renamed with no trouble.

I set /sys/module/block/parameters/events_dfl_poll_msecs to 2000 as you suggested and my test CD mounted without me having to do anything special.

I think the question about how to make the change permanent very much applies.

Well, this particular rule should be in /lib/udev/rules.d/60-persistent-storage.rules under "enable in-kernel media-presence polling" comment.
That's where it is in udev 200.

You mean these lines?



    # enable in-kernel media-presence polling
    ACTION=="add", SUBSYSTEM=="module", KERNEL=="block", ATTR{parameters/events_dfl_poll_msecs}=="0", ATTR{parameters/events_dfl_poll_msecs}="2000"




I also note this line at the beginning of the file:
    # do not edit this file, it will be overwritten on update



Am I the only person who is still using CD's?

I wonder how they manage to stay zero. This is an amd64 system.

Do you have any other files named 60-persistent-storage.rules in the dirs, udev reads ?

Cause that's the rule, so it looks like it's not getting applied for some reason.

The only one is in /lib/udev/rules.d.

I agree that it looks like it isn't being read.

I modified the 60-persistent-storage.rules as follows:


    # enable in-kernel media-presence polling

    ACTION=="add", SUBSYSTEM=="module", KERNEL=="block", ATTR{parameters/events_dfl_poll_msecs}="2000"


I don't see any error messages but it still didn't automount the CD.
