[Bug 789930] Re: [natty] boot hangs / udev vgchange deadlock in nested vgs?

[Wessel Dankers]

I was a little overzealous with the application of --noudevsync there,
only vgchange accepts that.

SUBSYSTEM=="block", ACTION=="add|change", ENV{ID_FS_TYPE}=="lvm*|LVM*", \
 RUN+="watershed sh -c '/sbin/lvm vgscan; /sbin/lvm vgchange --noudevsync -a y'"

Title:
  [natty] boot hangs / udev vgchange deadlock in nested vgs?

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: udev

  After upgrading a server system from lucid to natty the system is not booting any more.
  The boot stalls before mounting the root filesystem.

  After a while the following messages appear:
