Description Gregory Gulik 2007-09-26 14:04:23 UTC

Description of problem:

Upon start-up the default device for an installed DVD drive is /dev/sr0.  The
same thing happens when you select "Scan for devices" it does find the DVD drive
but the "node" is "/dev/sr0".  At least on Fedora 7 there is no /dev/sr0 device.
 The correct device is /dev/scd0

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

gnomebaker-0.6.2-1.fc7

How reproducible:

Always

Steps to Reproduce:
1. Start gnomebaker
2. try to burn a CD or DVD

  
Actual results:

:-( "/dev/sr0=/raid-array2/DVD_IMAGE.ISO": unexpected errno:No such file or
directory
The "no such file or directory" refers to /dev/sr0 because
/raid-array2/DVD_IMAGE.ISO does exist and is readable.

Expected results:

Gnomebaker should be able to find the correct device for the DVD drive and
successfully burn the DVD image.

Additional info:

Every time I start up gnomebaker I have to go to Edit -> Preferences -> Devices
and manually change the device to /dev/scd0.  After I do that gnomebaker works
just fine.

Comment 1 Tomas Smetana 2007-09-26 14:13:59 UTC

GnomeBaker takes the device node from /proc/sys/dev/cdrom/info and it says sr0
on F-7.  This has to be changed so that GnomeBaker takes device name from the
wodim/cdrecord output.

Comment 2 Gregory Gulik 2007-09-26 14:18:31 UTC

Why does /proc/sys/dev/cdrom/info have sr0 in the first place?

Is that incorrect or should there really be a /dev/sr0 device?

Comment 3 Harald Hoyer 2007-10-01 10:53:08 UTC

GnomeBaker can just glob("/dev/cdrom*) or glob("/dev/cdrw*") in rawhide.

Comment 4 Tomas Smetana 2007-10-01 11:16:15 UTC

This problem doesn't occur in rawhide.  In F-7 it's caused by udev that renames
/dev/sr* to /dev/scd* which makes /proc and /dev inconsistent.  The updated udev
should solve the issue.

Comment 5 Fedora Update System 2007-10-03 21:18:57 UTC

udev-115-4.20070921git.fc7 has been pushed to the Fedora 7 testing repository.  If problems still persist, please make note of it in this bug report.

 su -c 'yum --enablerepo=updates-testing update udev'

Comment 6 Michael Cronenworth 2007-10-04 15:49:47 UTC

The udev-115-4.20070921git.fc7 package leaves /dev/sr0 be and creates a
/dev/scd0 symlink. Works for me. Thanks!

Comment 7 Gregory Gulik 2007-10-05 18:00:49 UTC

The udev-115-4.20070921git.fc7 package fixed the GnomeBaker problem for me.

Thank you for the quick resolution.
