fio-format で "EB map missing" が表示され失敗したとき

More than 5 years have passed since last update.

ioDrive Duo に fio-format コマンドでフォーマットをかけようとしたところ、 Format failed: EB map missing.と表示され失敗しました。

$ sudo fio-format /dev/fct1
Creating a standard block device of size 320.00GBytes (298.02GiBytes).
  Using block (sector) size of 512 bytes.

WARNING: Formatting will destroy any existing data on the device!

fio-sure-erase を実行してみる

fio-sure-erase コマンドで完全消去を試してみます。

$ sudo fio-sure-erase /dev/fct1

その後サーバを reboot し、再度 fio-format を実行したところフォーマットすることができました。
