[Bug 890592] Re: Ejecting a CD or DVD manually does not unmount it

[Martin Pitt]

The first reason is that our current kernel package seems to have the
"block" module built in now, so the udev rule which is meant to set the
default in-kernel polling value doesn't work:

ACTION=="add", SUBSYSTEM=="module", KERNEL=="block",
ATTR{parameters/events_dfl_poll_msecs}=="0",
ATTR{parameters/events_dfl_poll_msecs}="2000"

This requires a sysctl.d setting now. Will add to udev package.

However, even when I set the polling interval manually, the kernel still
doesn't emit an eject_request uevent, even though it claims to:

$ cat /sys/block/sr0/events
media_change eject_request

I still need to investigate that.

Title:
  Ejecting a CD or DVD manually does not unmount it

Status in Nautilus:
  Unknown
Status in “udev” package in Ubuntu:
  In Progress

Bug description:
  PROBLEM

  On my laptop, pressing the hardware "eject" button on the DVD drive
  will pop out the disc, but it will still be treated as mounted by
  Nautilus. If I then put in another disc, it will still think that the
  files from the previous disc are there, as though it had not been
  ejected. This produces an error when I try to manipulate those files.

  I can't access the files from the new disc until I eject the old one
  using the button on Nautilus.

  HOW TO REPRODUCE

  1. Put a CD or DVD in the drive, close it, and let Nautilus mount it.
  2. Eject it using the hardware eject key.
  3. Put in a new CD or DVD.

  EXPECTED BEHAVIOR

  Nautilus will know when I ejected a disc.
