ZFS-Zpoolディスクの交換により、終了しないresilverプロセスが再起動します
壊れたドライブを、しばらくの間プールですでに使用されているタイプに交換しました。私が直面している問題は、resilverプロセスが再起動ループでスタックしているように見えることです。 zpool statusを確認すると、数秒前に再シルバープロセスが開始されたことがわかります。進捗率は0％のままです
例えば.
- スキャン：2017年6月1日木曜日09:13:27以降に進行中のresilver
- スキャン：2017年6月1日木曜日09:15:10以降に進行中のresilver
- スキャン：2017年6月1日木曜日09:18:11以降進行中のresilver
.。
何が問題になっているのかわかりません。これまでこの問題に遭遇したことはありません。コミュニティからのアドバイスをいただければ幸いです。

これを修正できず、ディスクを別のディスクに交換することで問題が解決しました。 SMARTエラーがログに記録されていない場合でも、ドライブに障害があると思われます。
