Title:
  Timed out Availability of block devices service

Status in lvm2 package in Ubuntu:
  Confirmed
Status in mdadm package in Ubuntu:
  Confirmed

Bug description:
  On a fresh Ubuntu 18.04 (64 bit) Server install, the blk-
  availability.service always killed by timeout at shutdown.

  I think the dependency of this service is bad, but I don't know what
  would be the good shutdown order for this.

  An almost same config has been worked on Xenial...

  The disk sub-system is
    * NVMe SSD
      * EFI partition
      * boot partition
      * LVM phisical volume
          * root logical volume
          * swap logical volume
          * data logical volume
    * 2 pcs. HDDs in RAID1 (but the md0 is not used yet)
