  mediascanner prevents unmounting usb device

Status in mediascanner2 package in Ubuntu:
  Fix Released

Bug description:
  Trying to unmount a block device I just mounted, I get the following
  error (sorry for not resetting the locale. It says "Device is busy"):

  :~$ sudo umount /media/tkluck/tjk-backup 
  umount2: Apparaat of hulpbron is bezig
  umount: /media/tkluck/tjk-backup: apparaat is bezig
  (Welke processen het apparaat gebruiken kan mogelijk
   gevonden worden met behulp van lsof(8) of fuser(1).)
  umount2: Apparaat of hulpbron is bezig

  I get the same error in a dialog window when trying to unmount from
  the file manager.

  Using lsof shows that the media-scanner daemon is the culprit:

  mediascan 2898 tkluck   26r   DIR  252,3 4096 47317999 

  Sending it

  sudo kill -9 2898

  solved this for me.

  This is on Ubuntu GNOME 14.04. I uninstalled the mediascanner2.0 to
  solve this "once and for all" (which has no other impact since I do
  not use Unity).

  My guess is that the scan usually finishes quickly after mounting. But
  because this particular drive contains a big filetree, it doesn't,
  resulting in the issue.

[Touch-packages] [Bug 1310186] Re: mediascanner prevents unmounting usb device

2016-12-08 Thread Michi Henning
There doesn't appear to be a way to be notified of unmount attempts at
the moment. There is an fschange modification about ten years ago
(http://stefan.buettcher.org/cs/fschange/), but that never made it into
the kernel.

It looks like it's impossible for mediascanner to automatically back off
when an unmount attempt is made.

You can kill the mediascanner process and then unmount. (Not of much
help to naive user, I admit.)

[Touch-packages] [Bug 1310186] Re: mediascanner prevents unmounting usb device

2016-10-13 Thread Michi Henning
It's difficult to see how to fix this. External devices are scanned
because people quite often use USB sticks or external drives with their
music collections.

I'm not sure whether it is even possible for mediascanner to find out
that some other arbitrary process has asked for a filesystem to be
unmounted. If so, the daemon could back off. If not, I don't know what
else it could/should do.

For what it's worth, placing a file called .nomedia into a directory
prevents scanning of that directory (and all its subdirectories).

[Touch-packages] [Bug 1310186] Re: mediascanner prevents unmounting usb device

2015-05-17 Thread Andreas E.
I wonder what is the benefit of scanning external drives that are
mounted only temporarily, especially when connecting other people's USB
sticks.

Since mediascanner is a process that was not launched manually by the
user, the confirmation on removal (device busy) is redundant, instead
mediascanner could probably shutdown silently whenever unmounting of the
device is requested (ie. unmounting should be done by no more than one
click in nautilus sidebar etc.).

The risk of bricking your own or even worse other people's USB stick by
improper removal (if a process is unperceivedly still running on the
drive) is too high so that it is questionable whether mediascanner
should run at all on external drives. I think this is a very critical
situation.

Title:
  mediascanner prevents unmounting usb device

Status in mediascanner2 package in Ubuntu:
  Confirmed

Bug description:
  Trying to unmount a block device I just mounted, I get the following
  error (sorry for not resetting the locale. It says Device is busy):

  :~$ sudo umount /media/tkluck/tjk-backup 
  umount2: Apparaat of hulpbron is bezig
  umount: /media/tkluck/tjk-backup: apparaat is bezig
  (Welke processen het apparaat gebruiken kan mogelijk
   gevonden worden met behulp van lsof(8) of fuser(1).)
  umount2: Apparaat of hulpbron is bezig

  I get the same error in a dialog window when trying to unmount from
  the file manager.

  Using lsof shows that the media-scanner daemon is the culprit:

  tkluck@ultrabook-tjk:~$ lsof /media/tkluck/tjk-backup 
  COMMANDPID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
  mediascan 2898 tkluck   16r   DIR  252,3   2498562 
/media/tkluck/tjk-backup
  mediascan 2898 tkluck   17r   DIR  252,3 4096 50855937 REDACTED

  mediascan 2898 tkluck   26r   DIR  252,3 4096 47317999 REDACTED

  Sending it

  sudo kill -9 2898

  solved this for me.

  This is on Ubuntu GNOME 14.04. I uninstalled the mediascanner2.0 to
  solve this once and for all (which has no other impact since I do
  not use Unity).

  My guess is that the scan usually finishes quickly after mounting. But
  because this particular drive contains a big filetree, it doesn't,
  resulting in the issue.
