Title:
  Udev has a race condition with device mapper devices

Status in “linux” package in Ubuntu:
  Won't Fix
Status in “udev” package in Ubuntu:
  Triaged

Bug description:
  When using lvm and/or dmraid devices, often times during boot up udev
  prints messages like:

  udevd-work[72]: inotify_add_watch(6, /dev/dm-6, 10) failed: No such
  file or directory

  I believe this is caused by a race condition somewhere causing udev to
  attempt to access the newly created dm device before the dev node
  actually appears in /dev.  Sometimes it seems to get as far as running
  blkid before the dev node appears, causing it to fail to identify the
  UUID of the device and create the /dev/disk/by-uuid symlinks.
