Hi Nicklas,

Thanks for the extra info!  This sounds like an issue with blkid (and/or
your system), rather than a cloud-init bug.  I've added a util-linux bug
task (which is the package that ships blkid), and I'm going to mark the
cloud-init bug task Invalid as I don't believe that there's anything we
can do to help you from our perspective.

If you think this is incorrect, please do let us know!


Thanks!

Dan

Title:
  ds-identify - stuck in uninterruptible sleep state

Status in cloud-init:
  Invalid
Status in util-linux package in Ubuntu:
  New

Bug description:
  We got recurring issues with the cloud-init/ds-identify process. It
  spawns sub-processes "blkid -c /dev/null -o export" which gets stuck
  in the "D" uninterruptible sleep state.

  The processes cannot be killed, so the only solution is to reboot the
  affected server.
