[Bug 1856560] Re: ds-identify - stuck in uninterruptible sleep state

[Dimitri John Ledkov]

[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-5.0.0-32-generic
root=/dev/mapper/ubuntu--vg-ubuntu--lv ro maybe-ubiquity

Could you please expalin what are you doing?

Because everything about this is odd. You are booting of LVM volume?
Running ubiquity desktop installer? And using cloud-init?

It would be interesting for you to describe your setup and suggest how
to reproduce your instance type.

Also you appear to run without a cloud hence nocloud seed.

If you are modifying cloud.config anyway, can you specify that ds-
identify should just use NoCloud?

journal.txt seems to be incomplete, it's not a full journal of boot with
this issue.

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.
