zfs運用メモ

Last updated at Posted at 2016-11-15

ディスクが壊れたとき

  • 物理的にディスクを入れ替える
  • zfs replaceを実行する

エラーがないとき

  • そのまま完了

エラーが有ったとき

  • データが一部破損していた場合resilverが止まるので対処する必要がある
  • なんのファイルが壊れたのわかるのでそれがファイルであれば削除する
  • スナップショットに残っているのであれば該当スナップショットを削除する
  • 元データが残っていれば上書きする

その他

raidz2にしとかないとresilver中に破損が発覚するとそのデータを捨て無くてはならない

 state: DEGRADED
status: One or more devices has experienced an error resulting in data
