zpool replaceは正常に実行されましたが、それでもzpoolreplaceをお勧めします。それは私に何を伝えていますか？
ドライブがraidz3で失敗しました（pci-0000:03:00.0-scsi-0:0:10:0）、そして私はそれを利用可能なスペア（wwn-0x5000c500858252ef）と交換しました：
pool: darkpool
state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
repaired.

予備は再銀化すると消えて、プールのメンバーになると思いました。しかし、DEGRADED状態は持続し、スペアはまだINUSE不良ドライブを埋めていました。
推奨はreplace the faulted device, or use use 'zpool clear' to mark the device as repaired.
clearの意味を完全に誤解しました。それは私の間違いです。事態を悪化させただけだと思います。
pool: darkpool
state: DEGRADED
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.

darkpool version 5 -
プールはUbuntu14.04で作成されたと思います
History for 'darkpool':
2016-07-15.10:38:13 [txg:5] create pool version 5000; software version 5000/5; uts hippocampus 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64
いいえ、誰がこれらの名前を設定したのかわかりません。Ubuntu18では問題にならないようですが、by-idを好みます。
Zpoolエラーのクリアが早すぎた可能性があります（resilverが進行中でした）。ただし、プールの状態に害を及ぼすべきではありませんでした。
プールを再シルバー化してから、zpool clear darkpoolを発行し、最後にzpool scrub darkpoolを実行します。これは、きれいなプールを持つのに十分なはずです。
