July 8, 2025Jul 8 Hi! My Unraid version is 7.0. After I rebooted my server, my zfs pool shows "Unmountable: wrong or no file system".I use "zpool import", it shows: pool: zpool id: 17974986851045026868 state: UNAVAIL status: One or more devices contains corrupted data. action: The pool cannot be imported due to damaged devices or data. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-5E config: zpool UNAVAIL insufficient replicas raidz1-0 UNAVAIL insufficient replicas sdc1 ONLINE sdd1 ONLINE sdi1 ONLINE 6057603923239297990 UNAVAIL invalid label sdk1 UNAVAIL invalid labelIt's strange. My pool name should be "zpool4t".Then I use "zdb -l /dev/sdx1" for my 5 driversroot@Tower:~# zdb -l /dev/sdd1 ------------------------------------ LABEL 0 ------------------------------------ version: 5000 name: 'zpool' state: 1 txg: 3114017 pool_guid: 17974986851045026868 errata: 0 hostname: 'Tower' top_guid: 10484232838912187944 guid: 9613584519376571584 vdev_children: 1 vdev_tree: type: 'raidz' id: 0 guid: 10484232838912187944 nparity: 1 metaslab_array: 135 metaslab_shift: 34 ashift: 12 asize: 20003911106560 is_log: 0 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 9780443222822920977 path: '/dev/sdc1' whole_disk: 0 DTL: 425 create_txg: 4 children[1]: type: 'disk' id: 1 guid: 9613584519376571584 path: '/dev/sdd1' whole_disk: 0 DTL: 424 create_txg: 4 children[2]: type: 'disk' id: 2 guid: 6499147292202988868 path: '/dev/sdi1' whole_disk: 0 DTL: 423 create_txg: 4 children[3]: type: 'disk' id: 3 guid: 6057603923239297990 path: '/dev/sdj1' whole_disk: 0 not_present: 1 DTL: 422 create_txg: 4 children[4]: type: 'disk' id: 4 guid: 13162368864450388321 path: '/dev/sdk1' whole_disk: 0 DTL: 421 create_txg: 4 features_for_read: com.delphix:hole_birth com.delphix:embedded_data com.klarasystems:vdev_zaps_v2 labels = 0 1 2 3root@Tower:~# zdb -l /dev/sdc1 ------------------------------------ LABEL 0 ------------------------------------ version: 5000 name: 'zpool' state: 1 txg: 3114017 pool_guid: 17974986851045026868 errata: 0 hostname: 'Tower' top_guid: 10484232838912187944 guid: 9780443222822920977 vdev_children: 1 vdev_tree: type: 'raidz' id: 0 guid: 10484232838912187944 nparity: 1 metaslab_array: 135 metaslab_shift: 34 ashift: 12 asize: 20003911106560 is_log: 0 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 9780443222822920977 path: '/dev/sdc1' whole_disk: 0 DTL: 425 create_txg: 4 children[1]: type: 'disk' id: 1 guid: 9613584519376571584 path: '/dev/sdd1' whole_disk: 0 DTL: 424 create_txg: 4 children[2]: type: 'disk' id: 2 guid: 6499147292202988868 path: '/dev/sdi1' whole_disk: 0 DTL: 423 create_txg: 4 children[3]: type: 'disk' id: 3 guid: 6057603923239297990 path: '/dev/sdj1' whole_disk: 0 not_present: 1 DTL: 422 create_txg: 4 children[4]: type: 'disk' id: 4 guid: 13162368864450388321 path: '/dev/sdk1' whole_disk: 0 DTL: 421 create_txg: 4 features_for_read: com.delphix:hole_birth com.delphix:embedded_data com.klarasystems:vdev_zaps_v2 labels = 0 1 2 3root@Tower:~# zdb -l /dev/sdi1 ------------------------------------ LABEL 0 ------------------------------------ version: 5000 name: 'zpool' state: 1 txg: 3114017 pool_guid: 17974986851045026868 errata: 0 hostname: 'Tower' top_guid: 10484232838912187944 guid: 6499147292202988868 vdev_children: 1 vdev_tree: type: 'raidz' id: 0 guid: 10484232838912187944 nparity: 1 metaslab_array: 135 metaslab_shift: 34 ashift: 12 asize: 20003911106560 is_log: 0 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 9780443222822920977 path: '/dev/sdc1' whole_disk: 0 DTL: 425 create_txg: 4 children[1]: type: 'disk' id: 1 guid: 9613584519376571584 path: '/dev/sdd1' whole_disk: 0 DTL: 424 create_txg: 4 children[2]: type: 'disk' id: 2 guid: 6499147292202988868 path: '/dev/sdi1' whole_disk: 0 DTL: 423 create_txg: 4 children[3]: type: 'disk' id: 3 guid: 6057603923239297990 path: '/dev/sdj1' whole_disk: 0 not_present: 1 DTL: 422 create_txg: 4 children[4]: type: 'disk' id: 4 guid: 13162368864450388321 path: '/dev/sdk1' whole_disk: 0 DTL: 421 create_txg: 4 features_for_read: com.delphix:hole_birth com.delphix:embedded_data com.klarasystems:vdev_zaps_v2 labels = 0 1 2 3root@Tower:~# zdb -l /dev/sdk1 failed to unpack label 0 failed to unpack label 1 failed to unpack label 2 failed to unpack label 3 root@Tower:~# zdb -l /dev/sdj1 failed to unpack label 0 failed to unpack label 1 failed to unpack label 2 failed to unpack label 3Please tell me what can I do next.
