[ILUG] LVM symlinks not created during startup

[Jean Francois Bucas]

Hi all,

anybody with some LVM/udev experience?

The following symlinks are not created at boot time.
/dev/my.vg.name/my.lv.name
/dev/mapper/my.vg.name-my.lv.name


When manually issuing udevadm trigger, all becomes fine
# udevadm trigger


(=== before triggering ===)
# udevadm info --export-db

[...]

N: dm-0
E: DEVNAME=/dev/dm-0
