Title:
  multipath-tools missing wwids can cause paths to be ignored on boot

Status in multipath-tools package in Ubuntu:
  Fix Released
Status in partman-multipath package in Ubuntu:
  New

Bug description:
  Booting a multipathed systems can fail in initramfs if the wwids file
  is not present and multipath-tools (with find_multipaths enabled) runs
  its detection before udev has completely detected all disk paths.

  Solution would be to either copy wwids file on the initramfs image so
  that it's available on boot, or to make sure udev runs and finds all
  paths before running the multipath detection in scripts/local-
  top/multipath.
