Looking at the output of zdb -l /dev/ada0 I see LABEL 1 has the old info where as zdb -l /dev/ada1 only shows the active pool zroot. So I guess the question is how do I get rid of LABEL 1 on ada0. I guess I could offline the disk, do a full zpool-labelclear on /dev/ada0 and then "replace" ada0p3 with ada0p3. But I wonder if there is a more surgical way to do it ? zdb -l /dev/ada0 failed to unpack label 0 ------------------------------------ LABEL 1 ------------------------------------ version: 5000 name: 'zbackup1' state: 0 txg: 37258100 pool_guid: 5819795054093255811 hostid: 2940363587 hostname: 'otherhost.sentex.ca' top_guid: 15407571356201067876 guid: 7177971506633653196 hole_array[0]: 1 vdev_children: 3 vdev_tree: type: 'raidz' id: 2 guid: 15407571356201067876 nparity: 2 metaslab_array: 115 metaslab_shift: 36 ashift: 9 asize: 12002364751872 is_log: 0 create_txg: 263935 children[0]: type: 'disk' id: 0 guid: 9271219886945262566 path: '/dev/da5' phys_path: '/dev/diskid/DISK-%20%20%20%20%20WD-WCC1P1023355' whole_disk: 1 DTL: 618 create_txg: 263935 children[1]: type: 'disk' id: 1 guid: 8131984913529158308 path: '/dev/mfisyspd8' phys_path: '/dev/diskid/DISK-%20%20%20%20%20WD-WMAWP0126093' whole_disk: 1 DTL: 617 create_txg: 263935 children[2]: type: 'disk' id: 2 guid: 10328589068509663454 path: '/dev/mfisyspd7' phys_path: '/dev/diskid/DISK-%20%20%20%20%20WD-WMAWP0079293' whole_disk: 1 DTL: 616 create_txg: 263935 children[3]: type: 'disk' id: 3 guid: 3414086086163178196 path: '/dev/mfisyspd6' phys_path: '/dev/diskid/DISK-%20%20%20%20%20WD-WMAUR0331605' whole_disk: 1 DTL: 615 create_txg: 263935 children[4]: type: 'disk' id: 4 guid: 7177971506633653196 path: '/dev/mfisyspd9' phys_path: '/dev/diskid/DISK-%20%20%20%20%20WD-WMAUR0387259' whole_disk: 1 DTL: 614 create_txg: 263935 children[5]: type: 'disk' id: 5 guid: 17460231907795801757 path: '/dev/da8p1' whole_disk: 1 not_present: 1 DTL: 262356 create_txg: 263935 features_for_read: com.delphix:hole_birth com.delphix:embedded_data labels = 1 ------------------------------------ LABEL 2 ------------------------------------ version: 5000 name: 'zroot' state: 0 txg: 61126347 pool_guid: 13987985424735542345 errata: 0 hostname: '' top_guid: 17259639802746798684 guid: 18413289395104510392 vdev_children: 1 vdev_tree: type: 'mirror' id: 0 guid: 17259639802746798684 metaslab_array: 34 metaslab_shift: 34 ashift: 12 asize: 1978918240256 is_log: 0 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 18413289395104510392 path: '/dev/ada0p3' phys_path: 'id1,enc@n3061686369656d30/type@0/slot@1/elmdesc@Slot_00/p3' whole_disk: 1 DTL: 110 create_txg: 4 children[1]: type: 'disk' id: 1 guid: 9245256067651064428 path: '/dev/ada1p3' phys_path: 'id1,enc@n3061686369656d30/type@0/slot@2/elmdesc@Slot_01/p3' whole_disk: 1 DTL: 4403 create_txg: 4 features_for_read: com.delphix:hole_birth com.delphix:embedded_data labels = 2 3
