Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.3 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  multipath keep failure after the interface is recovered

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  We encounter a multipath issue on Ubuntu 14.04.2 LTS.

  dm state (i.e. failed) cannot be recovered automatically when the
  interface is back. But path check state (i.e. faulty) can.

  In order to describe the issue clearly, the attached slides shows the detail of reproduce steps. 
  Meanwhile, attachment also includes the output from multipath tool. 

  P.S. We are writing the IO to the volume through dm device during the
  interface enable/disable.
