Public bug reported:
Binary package hint: gvfs
Hi. I am currently experiencing some problems with DVD-RAM media under
ubuntu lucid lynx, and I was wondering if you might recognize some of
the behaviour as being normal, or a bug.
What I do is insert a disk, then issue `mkudffs --media-type=dvdram
--utf8 /dev/sr0` and then `mount /media/cdrom0`. All seems to go well
and I get an entry that shows up as:
/dev/sr0 on /media/cdrom0 type udf (rw,nosuid,nodev,utf8,user=dan)
At this point, I tried a simple copy of the linux git repository
(~850mb), but 3 hours later it is still copying. With other small test
writes, I also noticed that when I issue a umount, the command blocks
for maybe 10 seconds, then returns, yet the drive light appears to
continue to be writting for at least 5 minutes past the umount. At
that point it starts spiking a nice'd load or something, on one of the
cores of my system to 100% and stays there until I eject the disk. The
problem is that ejecting the disk seems to mess up the copy as well.
And even after I eject, the load stays at 100% on one core.
As for the drive, it is:
wodim: Overview of accessible drives (1 found) :
-------------------------------------------------------------------------
0 dev='/dev/scd0' rwrw-- : 'HL-DT-ST' 'DVDRAM GH22NS50'
-------------------------------------------------------------------------
Current kernel: Linux wks 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11
08:03:28 UTC 2010 x86_64 GNU/Linux
It seems that even after I umount, a program called
gvfs-gdu-volume-monitor starts going nuts writting to the disc and
pegging one of the cores, followed by udevd using 100% after an
eject+reinsert. Correct me if I am wrong, but absolutely nothing
should be writting to any device after a umount, no?
Anyways, until I can track down exactly what might be interfering with
the writes, I would love to hear back on if I am just doing something
incorrectly. Any help would be appreciated. Thanks!
Dan
