 Posted: Sun Oct 24, 2004 7:22 pm Post subject: can't burn after installing udev |
 |
|
Hi, upgraded my kernel to 2.6 a little while ago. I wasn't having any problems with cd burning and the 2.6 kernel until I installed udev. My current kernel version is 2.6.9-gentoo-r1.
Here's the error message when I do 'cdrecord -scanbus':
| Code: |
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
|
Any ideas/help? It would be appreciated since I've been working on this for hours to no avail.
Thanks,
dq |

Hi!
Do you see your cd-rom at all?
It's strange if you can see it but can't record. I had the problem that that I didn't see the /dev/cdrom device at all. I added next line to my /etc/udev/rules.d/50-udev.rules:
| Quote: | | BUS="scsi", SYSFS{vendor}="QSI", SYSFS{model}="CDRW/DVD SBW-242", SYMLINK="cdrom" |
I don't know if it will solve your problem. But you may try it anyway 
You may find your vendor and model in /sys:
| Quote: |
cat /sys/bus/scsi/devices/0\:0\:0\:0\:/vendor
|
or similiar...
try it and tell me if it helps or not |

Now, I'm having major problems for no apparent reason.
I didn't do anything and now I can't boot into my 2.6 kernel (the 2.4 is fine). (Actually, all I did was run the`udev' program and then reboot). I get an error message saying my root partition has a bad superblock. But it doesn't!
I tried adding
in lilo.conf. But it didn't work!
This is getting really annoying! Any suggestions?
thanks so far,
dq |

Ok, I finally got udev working!! It involved deleting a file in /dev called .devfsd. Anyway, still can't burn but I haven't tried that thing you suggested.
Thanks,

I don't know whether this is your problem, but CD-burning changed in 2.6.8+ kernels, so you can no longer burn as a normal user. So far, I've found that the best solution is to use
| Code: | $ su
- or, if running an X frontend -
$ sux |
to become root, and burn.
sux works for k3b at least. (i don't use KDE, but I've found that k3b is still the most complete CD/DVD-burning frontend)
Btw. AFAIK, sux doesn't come with any other package, so if you don't have it already, you'll have to emerge it seperately.
Hope you get it working |

Nope, I added that information (the bus stuff) and I still cannot burn, i.e. my burner is still not detected by gtoaster.
When I do 'cdrecord dev=/dev/hdd -scanbus', I get:
| Code: |

scsibus: -2 target: -2 lun: -2

Which looks like no problem. Alternatively, I do 'cdrecord dev=ATAPI -scanbus' I get something slightly different:
| Code: |

0,4,0 4) *

Does this info provide any clue?
Thanks,

try editing /etc/security/console.perms
line might look like
| Quote: | | <console> 0600 <cdrom> 0660 root.cdrom |
and
| Quote: | | <console> 0600 <burner> 0660 root.cdrw |
try to change 0660 in second column to 0666
and reboot (I don't know which service you need to restart, guess hotplug) |

Ok, thanks to everyone here, I'm making progress. I'm not there yet but it's getting there. This command works for a normal user:
| Code: |
cdrecord dev=/dev/hdd -v -dummy "01 aquarela do brasil.mp3"
|
Of course, it will just burn the mp3 and not decode it. I haven't tried it w/o the `-dummy' option, but I'm sure it will work.
Now I'd like to get gtoaster working. Does anyone know how to configure it properly?
Thanks,
dq |

Alright, well I fooled around with gtoaster and I finally got it to work! The solution is kinda hoaky IMHO.
There's a setting for the SCSI ID and, from what I gather, the setting is usually something like: 0,1,0. No combination of numbers worked for me-- instead I put '/dev/hdd' there instead and it worked! Weird huh?
Anyway, thanks again for all your help.
