Udev doesn't create the device nodes for LVM volumes, these are |
| 10 |
created by the LVM tools, and should be symlinks to devices in |
| 11 |
/dev/mapper/. These are made after you do "vgchange -a y <group>". |

This is wrong...this link should be to /dev/mapper/vgusbhd-usbhd. |

This rule should not exist. |

Have you run "vgchange -a y vgusbhd"? |
