When vdev_psize increases, the location of labels 2 and 3 changes because their location is relative to the end of the device. The configs for labels 2 and 3 are written during the next spa_sync() because the vdev is added to the dirty config list. However, the uberblock rings are not re-written in their new location, leaving the device vulnerable to the beginning of the device being overwritten or damaged. This patch copies the uberblock ring from label 0 to labels 2 and 3, in their new locations, at the next sync after vdev_psize increases. Also, add a test zpool_expand_004_pos.ksh to confirm the uberblocks are copied.
