[Bug 635499] Re: Ignore broken directory permissions on UDF media

 

What are the full mount options that your disc is mounted with?  It
should include uid=yourid, which causes the UDF filesystem driver to map
the id ( -1 ) to be mapped to your UID, not the previously mentioned
dmode=.

  Description:	Ubuntu maverick (development branch)
  Release:	10.10

  When I insert an UDF formated DVD Nautilus should automount it, and
  open a window presenting the files contained on the DVD disk.

  Instead of this, the CD/DVD ROM icon disappears from the Computer
  location, there is an icon that appears and instantly disappears in
  the Nautilus location tab, and there is no window presented with the
  DVD files. It is as if the disk is not mounted at all. But this is not
  entirely true.

  The DVD I'm trying to read is inserted into an external DVD rom. It's
  an ordinary Asus DVD writer inserted into some generic rack (I don't
  think this is important, but I'm mentioning it).

  This is what dmesg reports after powering the rack:

  Inserting the UDF formated disk into the DVD reader.

  No window is open to present the DVD in nautilus, as if the DVD was
  not mounted at all. Before inserting the DVD there is a CD-ROM icon in
  Nautilus. Now it's gone too.

  But dmesg reports this:

  ...

  So the DVD was mounted after all!

  Going to /media/cdrom with Nautilus presents an binary file named
  Dilbert. It's type is unknown and size unknown also. Permissions
  reports that "The permissions of "dilbert" could not be determined"

  Trying to scan /media/cdrom using a console:

  ls -al /media/cdrom 
  ls: cannot access /media/cdrom/.: Permission denied
  ls: cannot access /media/cdrom/..: Permission denied
  ls: cannot access /media/cdrom/dilbert: Permission denied

  d????????? ? ? ? ?                ? ..

  Trying with sudo:

  sudo ls -al /media/cdrom
  [sudo] password for petar:

  Going to root mode.

  rpetar@aurora:~$ sudo -s

  root@aurora:/media/cdrom/dilbert/Season 1# cp Episode\ 107\ -\ Tower\ of\ Babel.avi /home/petar/Desktop/

  The file is copied as it should be.

  Unmounting the volume fails:

  root@aurora:/media/cdrom/dilbert/Season 1# umount /media/cdrom 
  umount: /media/cdrom: device is busy.
          (In some cases useful info about processes that use
           the device is found by lsof(8) or fuser(1))

  Now ejecting the DVD disk and inserting another one does not work,
  because the next disk is not auto-mounted anymore, probably because of
  the umount failure.

  And last for this first part of this report this is what my /etc/fstab
  looks like:

  proc            /proc           proc    nodev,noexec,nosuid 0       0

  I added the last line myself consulting another Maverick user because
  it was present on his system, but his installation was an upgrade from
  Lucid while my system is a clean Maverick installation done by using
  the ubuntu-10.10-beta-alternate-i386.iso installed on a USB startup
  disk. I'm mentioning this because I believe if the installation was
  done using an installation CD instead of  USB stick, this line would
  have been added to my /etc/fstab too (but I'm not sure about this).

  I think that it's also important to mention this:
  This disk was not accessible in Lucid too!
  I am not talking about just one UDF DVD that is not accessible, but something like 15-20 UDF formated DVDs!
  The DVDs are not mine but I know they are all created on a Windows XP machine and probably by Nero.
  The reason I'm reporting this bug is because this DVDs WERE READABLE on some of the previous versions of Ubuntu. I can't be sure about the specific version, but I think I could read them when I was using Ubuntu 9.04 (or it might have been Ubuntu 9.10)
  And most importantly, Maverick CAN MOUNT some UDF formated DVDs properly!!!
