テストまで１週間ぐらいやｗ何も勉強してねえ
このWebサーバーは仮想で動いてるんですけどその物理サーバーのHDDが入/出力エラーを吐いてて死にそうだなと
思ったので翌日に届くHDDを探していたところこのHDDがあった。
MARSHALのHDDって東芝かどっかのOEM？か何からしいってのを聞いた。
Amazonで6,980円でした。
参考にならない hdpram でベンチマーク取ってみた。
tetsuyai’s blog さんからスクリプトを借りました。
#!/bin/bash
if [ -z $1 ]
then
echo "Usage: `basename $0` FILESYSTEM" 1>&2
exit 1
fi
# It measures 12 times and displays a result.
for i in 0 1 2 3 4 5 6 7 8 9 10 11
do
sleep 10
_lines[$i]=`hdparm -t $1`
echo [$i] ${_lines[$i]}
_speeds1[$i]=`echo ${_lines[$i]} | cut -d' ' -f12`
done
# A result is rearranged into an ascending order.
IFS=$'\n'
_speeds1=(`echo "${_speeds1[*]}" | sort`)
# The minimum and the maximum are excepted and average value is calculated.
_sum=0
for i in 1 2 3 4 5 6 7 8 9 10
do
_speeds2[$i]=${_speeds1[$i]}
done
_avg=`echo "${_speeds2[*]}" | awk '{s+=$1}END{print s/10}'`
# Average value is displayed.
echo "AVG $_avg MB/sec"
１２回測定して、最小最大を抜いた平均をだしてくれるみたいです。
まずはProxmoxとWebサーバーが動いた状態のSSDで実行してみる。

今回買ったHDD。

割りと速い気がする。
と早速サーバーに入れて使ってますけどまた入/出力エラーが出た。
これは…
