After starting a multisession DVD with K3B, then trying to add to it with the "continue multisession" option, I get the following error,

"unable to proceed with recording: unable to unmount"

And the debugging output shows this,

"growisofs
-----------------------
umount: only root can unmount /dev/dvdrecorder from /media/dvdrecorder
:-( /dev/hdc: unable to proceed with recording: unable to unmount"


Why is it doing this? Do I have to login as root just to continue a multisession disc?? If so, that's pretty messed up, and is there a way around it??

Thanx!

I suppose you are using SUSE?

- run K3bSetup and change the device permissions (this should work if you don't have the above problems when running k3b as root).

- edit /etc/fstab to disable automounting (subfs) for the DVD recorder, e.g.:

/dev/dvdrecorder /media/dvdrecorder auto ro,noauto,user,exec,iocharset=utf8 0 0

(not 100% sure if these options are optimal, but they should work)

Yes, running suse 10.0. I ran k3bsetup, and I don't see how I can change the permissions. And for the record, yes, I could overcome my problem successfully if I ran k3b as root user, so it does appear to be the permissions. But I don't see how to change it in k3bsetup. It says "check the devices whose permissions you want to be changed." Both devices are checked and the permissions are listed as follows for each...

"666.root.disk" for one, and
"666.tom.disk" for the other one.

How do you change it?

And if I disable automounting doesn't that mean that my drives won't be mounted when I login to kde? I don't want that to happen where I have to mount them manually.

Thanx for the help!

If the "New permissions" tab says "no change", k3b is happy with the current state. You can try to change the ownership of your first (currently owned by root) device manually (as root): chown tom /dev/<the resp. device>

If you disable automatic mounting for your CD/DVD drive, it only means you won't get a pop-up when you enter a medium. You'll need to mount the drive either manually (command-line) or much easier through an icon on your desktop (Right-click desktop -> Create New -> Link to device).

Ok, I've changed the ownership, and I'm fine with disabling automatic mounting as you've described, so I'll do that also. I don't like it popping up when I put in a disc anyhow. I never use that feature and always tell it to stop doing it.

Thanx for the help!

Here is what fstab has for my recorders. Should I change them to the code you've given?

/dev/dvdrecorder /media/dvdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
/dev/dvdrecorder2 /media/dvdrecorder2 subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0

Thanx!

After changing the device permission, did the problem disappear?

Otherwise, yes, try the above code. Make a backup of fstab first, so you can restore the settings in case of problems.
