vdev_id support for device link aliases Add a vdev_id feature to map device names based on already defined udev device links. To increase the odds that vdev_id will run after the rules it depends on, increase the vdev.rules rule number from 60 to 69. With this change, vdev_id now provides functionality analogous to zpool_id and zpool_layout, paving the way to retire those tools. A defined alias takes precedence over a topology-derived name, but the two naming methods can otherwise coexist. For example, one might name drives in a JBOD with the sas_direct topology while naming an internal L2ARC device with an alias. For example, the following lines in vdev_id.conf will result in the creation of links /dev/disk/by-vdev/{d1,d2}, each pointing to the same target as the device link specified in the third field. # by-vdev # name fully qualified or base name of device link alias d1 /dev/disk/by-id/wwn-0x5000c5002de3b9ca alias d2 wwn-0x5000c5002def789e Also perform some minor vdev_id cleanup, such as removal of the unused -s command line option.
