 Posted: Tue Jan 15, 2008 6:15 am Post subject: k3b not finding CD/DVD burner |
 |
|
I'm trying to get k3b fired up on a relatively clean Gentoo install (2.6.21-r4). This is on a Dell Latitude
D820 laptop with a built-in DVD burner.
The burner is recognized at boot-up, it is assigned a SCSI ID, and udev gives it an 'sg' character device.
Output from dmesg:
| Code: | scsi 1:0:0:0: CD-ROM _NEC DVD+-RW ND-6650A 102C PQ: 0 ANSI: 5
scsi 1:0:0:0: Attached scsi generic sg1 type 5 |
/dev/sg1 exists and appears to have the correct permissions:
| Code: | reverb ~ # ls -l /dev/sg1
crw-rw---- 1 root cdrom 21, 1 Jan 14 19:41 /dev/sg1 |
What I don't see is a block device that k3b will recognize as something it can use to write to the burner.
I would have expected that udev would have also created an "sr" or "scd" block device, but I could be mistaken.
My udev config is vanilla - I haven't made any special hacks to it.
The user who is trying to use k3b is in the cdrom group.
I have a feeling I'm missing something simple here, but I'm having a devil of a time finding it...
Thanks in advance

This appears to be accurate. The hard drive is serial ATA, so it shows up as a SCSI device.

So start with the following beginning and enjoy - don't know what you want to do exactly.

What I'd like to be able to do is burn from k3b. k3b reports that it can't find a CD/DVD
writer at start-up and won't use /dev/sg1 if I explicitly tell it to because it's not a block device.
k3b knows the drive is there because it resolves the bus/id/lun triplet for /dev/sg1.
| Code: | (K3bDevice::DeviceManager) SCANNING FOR GENERIC DEVICES.
(K3bDevice::Device) could not open device /dev/sg0 for reading
(Permission denied)
bus: 1, id: 0, lun: 0
Could not resolve /dev/sg2
(K3bDevice::Device) could not open device /dev/sg2 for reading
(No such file or directory) |
/dev/sg0 is the character device for my SATA hard drive, so I understand why k3b can't open it. |

I checked and right now an equivalent block device is not being created for /dev/sg1.
No /dev/sdb*, no dev/sr*, no /dev/scd*, no /dev/hd* |

trouble with drive recognition...

This problem existed in 0.12.17. I tried upgrading to 1.0.4, which is what's installed right now, and the
same problem still exists. |

I'm not dead-set on using k3b - it's just one of the few Linux CD/DVD burning apps I've used in the past that worked straight away  .
I've tried many others (eroaster, GNOME CD writer, xcdroast, brasero, etc) and I found most of them to be lacking in one way or another.
I'm open to suggestions on other apps to try. They must be able to burn audio and data CDs and DVDs, regular source files
or ISO images. |

The question is...how is that is just k3b that is not working ? I just have a phisically attached drdrw right now.....
However I tried to disable AHCI , deleted udev rules and remerged udev, this time I don't find a "persistent cd .rules" or something like this, so probably is udev related.
| Code: | gentoo gas # sg_map
/dev/sg0 /dev/sda
/dev/sg1 /dev/sdb
/dev/sg2
|
Why is scsi?
P.S. IMO this is not a multimedia issue, should be moved.... |

...donkey. I even asked.
Character devices named sgX are generic scsi that are mapped to blocked devices, it means that the kernel rconsiders them scsi devices. I didn't have SCSI CDROM support in the kernel and hence it couldn't map the device to a block one.
With the new kernel I finally have a "70-persistent-cd.rules" in /etc/udev/rules and

I looked through my udev configs and ran a 'udevtest /class/scsi_device/1:0:0:0' and I noticed that there was no output
after udevd tried to do a 'modprobe mod_sr', which would create the /dev/sr* block devices that k3b is looking for...
I checked my kernel config and sure enough, there were some options that needed to be enabled. Specifically I enabled:
Device Drivers -> SCSI Device Support -> SCSI target support
Device Drivers -> SCSI Device Support -> SCSI CDROM support
I enabled these options, rolled a new kernel and rebooted. I could have also built the SCSI CDROM support as a module
and tested without needing to reboot, but I opted to roll a new kernel. When I rebooted, I saw good things in dmesg:
| Code: | sr0: scsi3-mmc drive: 24x/24x writer cd/rw xa/form2 cdda tray
sr 1:0:0:0: Attached scsi CD-ROM sr0
sd 0:0:0:0: Attached scsi generic sg0 type 0
sr 1:0:0:0: Attached scsi generic sg1 type 5 |
and now the block device /dev/sr0 exists, with the correct permissions:
| Code: | | brw-rw---- 1 root cdrom 11, 0 Jan 17 13:13 /dev/sr0 |
k3b no longer complains that it can't find a CD/DVD writer.
The next issue I'm wrestling with is that cdrecord is now unhappy and won't write CDs, based on the debugging output from k3b:

I tested that last night. Running k3b as root works, so it looks like it's down to being a permissions problem.
/dev/sr0 looks like it has the right permissions and the non-root user I originally tried to use k3b as is in the "cdrom" group. |

Try with cdrkit instead of cdrtools.

| This may be a dumb question, but if it's only a permissions issue at this point, are you sure that you ran 'K3BConfig' (or whatever the K3B config program is called)? |
