[Bug 558926] Re: Open files on ejected media cause automount of new media to break

 

Phillip Susi, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11.1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Package changed: udisks (Ubuntu) => linux

Title:
  Open files on ejected media cause automount of new media to break

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Open a file on a cdrom, perhaps as simply as changing the working
  directory of a shell to a location in /media/cdrom, then eject the
  disc.  The filesystem is forcibly unmounted, so it no longer appears
  in df, mount, or /proc/mounts, though it appears to still actually be
  sort of mounted since you can run stat . from the shell.  The kernel
  begins complaining filling /var/log/kern.log with messages like:

  VFS: busy inodes on changed media or resized disk sr0

  At this point the drive has vanished from view in nautilus.  It no
  longer appears on the places menu or in the computer folder.  If you
  insert a different disc it also will not show up in nautilus and you
  can not mount it through the gui until whichever processes that still
  have file descriptors open on files on the ejected media are closed.
