[Bug 1754506] Re: AutoFS does not automatically umount SMB shares

[ChristianEhrhardt]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers
to get help for this sort of problem here:
http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it
helpful to read "How to report bugs effectively"
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful
if you would then provide a more complete description of the problem,
explain why you believe this is a bug in Ubuntu rather than a problem
specific to your system, and then change the bug status back to New.

** Changed in: autofs (Ubuntu)
       Status: New => Incomplete

Title:
  AutoFS does not automatically umount SMB shares

Status in autofs package in Ubuntu:
  Incomplete

Bug description:
  Description:    Ubuntu 17.10
  Release:        17.10

  autofs:
    Installed: 5.1.2-1ubuntu1
    Candidate: 5.1.2-1ubuntu1
    Version table:
   *** 5.1.2-1ubuntu1 500
          500 http://de.archive.ubuntu.com/ubuntu artful/main amd64 Packages
          100 /var/lib/dpkg/status

  Kernel: self-built 4.15.6

  What I expect:
  I expect AutoFS to automatically unmount my samba share after the timeout. However, it does not. The share is still mounted.
  I've turned the autofs debug output in the kernel module. As far as I can tell, the kernel thinks the cifs mount is still busy.

  I'm using the smb automount script provided by the package: /etc/auto.smb. I've just added an additional cifs parameter(vers=2.0).
  My auto.master looks as follows:
  /media/smb/      program:/etc/auto.smb
