GELI の書き込みエラーを ZFS が処理をした: uyota 匠の一手

現在、FreeBSD 8.4-RELEASE で ZFS を利用中。ZFS は GEOM ELI の上に作られている。

GELI に書き込みエラーがあった。

心配でデータを調べたところ、表だった問題はない。

zpool status で調べたところ、問題を感知し対応処理を行ったとある。

% zpool status
  pool: zfs
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.
