Title:
  [SRU] clvm start error missing /var/run/lvm

Status in “lvm2” package in Ubuntu:
  Confirmed
Status in “lvm2” source package in Precise:
  Fix Committed
Status in “lvm2” source package in Quantal:
  Confirmed

Bug description:
  [Impact]
  This problem impacts cLVM in every use case. Before starting cLVM doesn't create /var/run/clvm. This is true for cLVM standalone and cLVM resource agent.

  [Development Fix]
  There is not fix in Ubuntu-Q, since it's not open yet.

  [Stable Fix]
  Proposed fix is a minimal change for cLVM init scrit and cLVM RA. In both cases, before starting the daemon, /var/run/lvm is created in case it doesn't exist already.

  [Test Case]
  1. Install Ubuntu 12.04
  2. Install clvm package
  3. Reboot the system
  4. Without the patch, clvmd won't be running

  [Regression Potential]
  Without the patch, clvmd can't start at all. There are no known regressions that might be caused by creating /var/run/lvm directory.

  [Original report]

  ubuntu:                         12.04 precise
  clvm:                              2.02.66-4ubuntu7

  "/etc/init.d/clvm start" fails because clvm is missing "/var/run/lvm"
  directory.

  Possible solution:
  Add "mkdir -p /var/run/lvm" to "do_start()"-Function in "/etc/init.d/clvm"-Script
