The exit status seemed not to signal the error.

Please clarify following. Is the exit status the only thing you want to report and discuss?


Yes. For present purposes. Here is the section of bash:-

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
if
  ! $burner $burner_opt ${mount_device}=$container;
  then
   read -p "Failure! Press enter to try again: " ;
   rewrite_dvd
fi
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

where $burner=growisofs etc.

I find that growisofs fails like this rarely on DVD-RWs. Retrying succeeds (I assume that it could fail again, but the probability is so low that I haven't seen that).

Basically I wonder how come recording was hanging
@0.0x for some time prior failing with depicted code. But if you know
why and for any particular reason don't want to share it, I can respect
that. In which case just confirm that the only thing you genuinely
interested in is exit status from growisofs in similar situation.

My immediate interest is getting reliable backups by retrying automatically even with bad media. So I want my script to see the failure and not throw away 4.3Gb of data! Hence my overriding interest in the exit code as the first priority.

Of course, I am also interested in why these failures happen occasionally on good media.

Here is dvd+rw-mediainfo on the disc that failed, *after* a second successful write of the same data (manual intervention):-

I have seen similar failures (I can't swear to the same error code) on another machine using a Pioneer DVD-104 drive - with the latest firmware.

Of course, I would love both problems to be solved, but I can't afford to have bad backups, so my priority is to work around failures, although I would prefer if they did not happen :-)

You have the right to expect non zero code, but it apparently doesn't do that...


Hope I got my bash right :-)

Well, must be a bug and I'll look into it, but [unfortunately]
not right away. Confirm that presented above are really *last* lines
from growisofs. A.

Those were the last lines displayed when run from within the script. As you saw it burned successfully at the right 1x speed for something like 45 minutes. I just erased the offending disc manually with dvd+rw-format and reran the same growisofs also manually. With success as you saw.


Hope this is useful. Thanks for all your magnificant work.
