3ware 9650SEでHDDの不良セクタに対処する
我が家のネットワーク環境には、3ware 9650SE-4LPML で RAID 運用しているサーバが 2 台ある。そのうち 1 台、この blog 用の MySQL も稼動しているマシンの 3DM2 から以下のようなメールが来た。
May 24, 2012 02:02.03PM - Controller 0 ERROR - Drive timeout detected: port=1
タイムアウトしただけでデグレードはしていないので HDD の故障というわけではない。そこで、smartmontools で S.M.A.R.T. 情報を取得してみた。
通常、ハードウェア RAID カードの場合、RAID カード上のプロセッサが各 HDD にデータを読み書きする仕様になっている。そのため、ホスト側の CPU からはドライバがなくても RAID アレイが 1 台のディスクドライブに見えるしブートも可能となる反面、実ドライブにアクセスすることはできない。だが、3ware や LSI の RAID カードの場合、smartctl にオプション -d 3ware,N を追加することで実ドライブの S.M.A.R.T. 情報を取得することができる。N はポート番号で、デバイスファイルは /dev/twaX を指定する。X はコントローラ番号となる。
今回は 1 番ポートでタイムアウトが発生しているので、1 番ポートのドライブを確認する。
# smartctl -a /dev/twa0 -d 3ware,1

SMART overall-health self-assessment test result が PASSED なので、ドライブに致命的な問題が発生しているわけではなさそう。稼働時間が 35,613 時間 = 4 年 23 日 21 時間と相当長く稼動しているドライブだが、問題なのは Current_Pending_Sector が 3 になっていることで、これは不良セクタのうち再配置がまだのセクタの数らしい。セクタに障害が発生しているのか確認するため、自己テストを実行する。

容量と I/O 性能にもよるが概して時間がかかるので、寝るなり仕事をするなりして完了予定時間まで待つ。完了したらドライブ内にログが残るのでそれを確認する。

やはり問題があるらしい。Bad block HOWTO for smartmontools によると、エラーのあるセクタに無理やりファイルを作成してそのセクタを読まないようにすればいいらしい。これは大昔の MS-DOS にあった CHKDSK にもあった機能ではある。ただ問題は、このドライブが RAID カードにぶら下がっていて RAID5 を構成しているということ。
このような場合、RAID カード側で対処できるらしい。3ware 9650SE の場合、RAID アレイのベリファイを行えば自動的に修復してくれる。ベリファイは 3DM2 から Management → Maintenance で「Verify Unit」を押下するか、tw_cli より
# tw_cli //poseidon> maint verify c0 u0 start
のどちらかで即時に実行できる。ただ、今回は 9650SE 側で土曜 0 時より定時ベリファイをするようになっていた(デフォルト設定)ので、それで対応できた。
ベリファイでセクタが再配置されれば、それがログに表示される。
tw_cli でも確認できる。

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Current_Pending_Sector が 0 となり、かわりに Reallocated_Sector_Ct と Reallocated_Event_Count がそれぞれ 1 になっている。これで修復完了となる。
このマシンは他にも PostgreSQL に某相場情報が 1 億行以上入っていたりと割と大量のデータを保存していたりする関係で、予備ドライブを 1 本確保してある。それに交換しようか迷ったが、アレイがデグレードしていないこと、息子がおもちゃにすることがあり、投入する際にチェックする必要もあることから今回はセクタの再配置のみで済ませることにした。
