Comment 104 for bug 527666

Upon debugging further, it seems mountall is waiting for /dev/HEBEX/WOO_BASE, and rightly so. After skipping with 'S' during boot, here is what we see:

root@malorent:~# lvscan
  ACTIVE '/dev/HEBEX/WOO_BASE' [1.00 GiB] inherit
  ACTIVE '/dev/HEBEX/WOO_LOG' [1.00 GiB] inherit
  ACTIVE '/dev/HEBEX/WOO' [5.00 GiB] inherit
  ACTIVE '/dev/HEBEX/WOO_PROG' [2.00 GiB] inherit
  ACTIVE '/dev/HEBEX/VAR_LOG' [3.00 GiB] inherit

root@malorent:~# ls -l /dev/mapper/

lrwxrwxrwx 1 root root 24 Apr 23 14:57 WOO_PROG -> ../mapper/HEBEX-WOO_PROG

root@malorent:~# lvdisplay /dev/HEBEX/WOO_BASE
  /dev/mapper/HEBEX-WOO_BASE: open failed: No such file or directory
  /dev/mapper/HEBEX-WOO_BASE: open failed: No such file or directory
  --- Logical volume ---
  LV Name /dev/HEBEX/WOO_BASE
  VG Name HEBEX
  LV UUID 1an8Zg-aYse-AkF3-NGs2-0BGF-4mfO-1m3wUA
  LV Write Access read/write
  LV Status NOT available
  LV Size 1.00 GiB

So LVM finds the missing device internally, but the device is not created by udev.
