Description Graham Cole 2001-09-03 17:24:27 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2) Gecko/20010705

Description of problem:
when i try to mount a multisession CD i get the following error:

[diakka@charon diakka]$ mount /mnt/dvd
/dev/dvd: Input/output error
mount: I could not determine the filesystem type, and none was specified

the fstab entry for this filesystem is:
0 0

Here are the entries in the /dev directory:

lrwxrwxrwx    1 root   root          4 Jun 13 20:37 /dev/dvd -> scd0
brw-------    1 diakka disk     1,   0 Mar 23 23:38 /dev/scd0

this is what happens when i specify a filesystem as root:
[root@charon /root]# mount -t iso9660 /dev/dvd /mnt/dvd
mount: block device /dev/dvd is write-protected, mounting read-only

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  put the previous filesystem entry in to fstab
2.  put a multisession CD in the drive (mine is Paul van Dyk - out there
and back - CD 2
3.  as the device owner do mount /dev/dvd

Additional info:

I am using a Lite-On LTD-163 16x DVD drive set to master on the first IDE
using scsi emulation.

What happens if you specify a filesystem as non-root?
