外付けUSB SATAディスクのS.M.A.R.T.監視

smartdの起動が失敗している

# /etc/init.d/smartd start
 * Starting smartd ...
 * start-stop-daemon: failed to start `/usr/sbin/smartd'
 * Failed to start smartd
 * ERROR: smartd failed to start

これだけでは何が原因かわからず放置していたが、調査することに。

syslogを確認すると、「Unable to register device /dev/sdb (no Directive -d removable). Exiting.」という記述があり、リムーバブルメディアなので、ストレージの種別を特定できないため、起動を諦めているようだ。

ここまで分かれば、対応は早い。ネットで調べると、デバイスの種類の設定は-dで行い、SATAの場合は「-d sat」とのこと。

/etc/smartd.confの設定に-d satを追加

# grep -v "\(^ *#\)\|\(^ *$\)" /etc/smartd.conf
/dev/sda -a -o on -S on -s (S/../.././01|L/../../6/01) -m root
/dev/sdb -a -o on -S on -s (S/../.././01|L/../../6/01) -m root -d sat

起動できるようになった
