Title:
  blk-availability unmounts filesystems before applications have
  finished using them

Status in lvm2 package in Ubuntu:
  Confirmed

Bug description:
  This bug is similar to the following:

    Red Hat - https://bugzilla.redhat.com/show_bug.cgi?id=1701234#c2
    Debian - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946882

  The blk-availability service is short-cutting
  RequiresMountsFor=<paths> dependencies during system shutdown and
  unmounting filesystems before those services have stopped, resulting
  in data file corruption and/or data loss.

  This can be worked around by adding "After=blk-availability.service"
  to the unit file for the service in question, but this is not self-
  evident and shouldn't be necessary.
