Title:
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:
tkluck@ultrabook-tjk:~$ lsof /media/tkluck/tjk-backup
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mediascan 2898 tkluck 16r DIR 252,3 249856 2
/media/tkluck/tjk-backup

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.
