Linux でハードディスクの S.M.A.R.T 情報の取得
S.M.A.R.Tとは...
S.M.A.R.Tは「Self Monitoring, Analysis, and Reporting Technology」の略で、HDDが自身の障害を自己診断して、ユーザに報告するインテリジェントな機能である。
smartmontoolsインストール
smartctlを利用するためには、smartmontoolsパッケージをインストールする。
$ sudo dnf install smartmontools

S.M.A.R.T 情報の取得
S.M.A.R.T 情報を取得するには、以下のコマンドを実行する。
$ sudo smartctl -a /dev/sda
SATAのRAIDカード経由の場合は、-d ata オプションを追加する。
$ sudo smartctl -a -d ata /dev/sda
HighPoint RocketRAID カード経由の場合は、-d hpt,L/M または -d hpt,L/M/N オプションを追加する。
L = コントローラID(1～4)
M = チャネル番号(1～8)
N = PMPort番号(1～5)
$ sudo smartctl -a -d hpt,1/1/1 /dev/sdb
このとき指定するデバイス名(/dev/sdb)は、RAIDカード配下のものであればどれでもよい。
デバイス名を調べるには、以下のコマンドを実行する。
$ sudo parted -l
モデル: HPT DISK_2_0 (scsi) ディスク /dev/sdb: 128GB セクタサイズ (論理/物理): 512B/512B パーティションテーブル: msdos 番号 開始 終了 サイズ タイプ ファイルシステム フラグ 1 32.3kB 210MB 210MB primary ext3 boot 2 210MB 128GB 128GB primary lvm モデル: HPT DISK_2_1 (scsi) ディスク /dev/sdc: 2872GB セクタサイズ (論理/物理): 512B/512B パーティションテーブル: gpt 番号 開始 終了 サイズ ファイルシステム 名前 フラグ 1 17.4kB 2872GB 2872GB msftres モデル: Linux device-mapper (linear) (dm) ディスク /dev/mapper/vg_monster-lv_swap: 4295MB セクタサイズ (論理/物理): 512B/512B パーティションテーブル: loop 番号 開始 終了 サイズ ファイルシステム フラグ 1 0.00B 4295MB 4295MB linux-swap(v1) モデル: Linux device-mapper (linear) (dm) ディスク /dev/mapper/vg_monster-lv_root: 2996GB セクタサイズ (論理/物理): 512B/512B パーティションテーブル: loop 番号 開始 終了 サイズ ファイルシステム フラグ 1 0.00B 2996GB 2996GB ext4
/dev/sdb または /dev/sdc が HighPoint RocketRAID のアレイであることが分かる。
RAID 0,1,5 アレイを構成するディスクの S.M.A.R.T 情報の取得
1つのコントローラに複数のチャネルが存在しハードウェアRAIDにて RAID0,1,5 などのアレイを構成している場合は、
Linux上からは1つのアレイを1つデバイスとして認識している。
例えば、物理ディスク1～4を利用してRAID5のアレイを2つ構成している場合、
RAIDカードのチャネル 物理ディスク アレイ Linuxデバイス hpt チャネル1 ----> Disk1 --+ hpt チャネル2 ----> Disk2 | --> RAID5_0 --> /dev/sdb hpt チャネル3 ----> Disk3 | --> RAID5_1 --> /dev/sdc hpt チャネル4 ----> Disk4 --+
コントローラID,チャネル番号,PMPort番号を指定することで、Linuxデバイス(/dev/sdb または /dev/sdc)を通して、
物理ディスクの S.M.A.R.T 情報を取得できる。
$ sudo smartctl -a -d hpt,1/1/1 /dev/sdb --> Disk1の情報を表示 $ sudo smartctl -a -d hpt,1/2/1 /dev/sdb --> Disk2の情報を表示 $ sudo smartctl -a -d hpt,1/3/1 /dev/sdb --> Disk3の情報を表示 $ sudo smartctl -a -d hpt,1/4/1 /dev/sdb --> Disk4の情報を表示
$ sudo smartctl -a -d hpt,1/1/1 /dev/sdc --> Disk1の情報を表示 $ sudo smartctl -a -d hpt,1/2/1 /dev/sdc --> Disk2の情報を表示 $ sudo smartctl -a -d hpt,1/3/1 /dev/sdc --> Disk3の情報を表示 $ sudo smartctl -a -d hpt,1/4/1 /dev/sdc --> Disk4の情報を表示

Vendor Specific SMART Attributes with Thresholds
注目すべき情報は、
| ID# | ATTRIBUTE_NAME | 意味 |
|---|---|---|
| 5 | Reallocated_Sector_Ct | ハードディスクが読み・書き・検証エラーを見つけ、代替させた不良セクタ数。通常、代替セクタが発生しても気が付かないが、より多くのセクタが代替されるほど、ディスクの読み書きに影響を及ぼす。 |
| 196 | Reallocated_Event_Count | 不良セクタから予備領域にデータを移した回数。データ移行に失敗した数も成功した数と同様にカウントアップされる。 |
| 197 | Current_Pending_Sector | 不安定なセクタ数。代替セクタに再配置されるのを待っているセクタの総数で、正しく読み取りできたばあいは除かれる。但し、エラーが発生する場合は代替セクタに移されて、不良セクタはマークされる。この値がゼロで残るならば、対応する領域の質が低いことを示す。 |
| 198 | Offline_Uncorrectable | 修復できないセクタの読み書き時のエラーの量を示す。この値が増えることは、ディスクの欠陥・機械的なサブシステムに問題があることを示す。 |

SMART Error Log Version: 1
Warning: ATA error count 758 inconsistent with error log pointer 5
ATA Error Count: 758 (device log contains only the most recent five errors)

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 758 occurred at disk power-on lifetime: 2665 hours (111 days + 1 hours)
When the command that caused the error occurred, the device was in an unknown state.
