next-2008-11-28 : can't mount UDF DVD

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

With next-2008-11-28, I was unable to mount an UDF-formatted DVD-RW:

~$ mount -oro -t udf /dev/sr0 /media/cdrom/
mount: Not a directory

There was no problem with 2.6.28-rc6.

I made a bisection:

commit 33284bdf40f88160a154202510b27d983138c805
Author: Marcin Slusarz <marcin.slusarz@xxxxxxxxx>

    udf: implement mode and dmode mounting options

    "dmode" allows overriding permissions of directories and
    "mode" allows overriding permissions of files.

Indeed, with this commit, I *must* use the dmode option to mount my DVD:

~$ sudo mount -oro,dmode=0755 -t udf /dev/sr0 /media/cdrom/
~$ grep /media/cdrom /proc/mounts 
/dev/scd0 /media/cdrom udf ro,mode=177777,dmode=755,utf8 0 0
~$ ls -la /media/cdrom/

...

Althought I was able to mount it with no special option on 2.6.28-rc6:

~$ sudo mount -oro -t udf /dev/sr0 /media/cdrom/
~$ grep /media/cdrom /proc/mounts 
/dev/scd0 /media/cdrom udf ro,utf8 0 0
~$ ls -la /media/cdrom/
