どのSATAポートに繋げたHDDがどこにマウントされてるか調べる方法

最初に全部入れると、どこのSATAポートがどのHDDかいつも忘れるれるのでメモ

インストール

#yum -y install smartmontools

# smartctl /dev/sda -i
# smartctl /dev/sdb -i
# smartctl /dev/sdc -i
# smartctl /dev/sdd -i
# smartctl /dev/sde -i

sdbに何のHDDが刺さってるか確認
Device ModelとかSerial NumberをHDDに書いてあるシール？と照らし合わせる

# smartctl /dev/sdb -i

CloudStackのチューニングしてみた

投稿日時: 2015年12月9日投稿者: sekki

返信

Apache CloudStack Advent Calendar 2015の12月9日の分を担当します。

80人くらいが同時にインスタンスを建てようとすると、APIがロック？と言うか、
画面更新などはできるが実行結果が帰ってこない状態（極端に遅いだけ？）になりました。
解決方法がよく分からず、#CloudStack　のハッシュタグを付けてツイートしたら解決方法を教えてくださったので、
メモ程度ですが、残しときます。

※時間がなく、今この値で動かないからこんぐらいにしとけば動くだろう　っと言う適当さです。

環境
CentOS 6.6
CloudStack 4.4.4
java version “1.7.0_85”
mysql Ver 14.14

cloudstack大人数で一斉にインスタンス作るとAPIがロック？（何か操作してもレスポンスが帰ってこない）されます。対処法教えて下さい　#cloudstack

@sekki_net グローバル設定のapi.throttling.maxをチューニングしてみるのはどうでしょう。#cloudstack https://t.co/K1QIw8O3P9 pic.twitter.com/nthr8zNtsQ

@giraffeforestg 解答ありがとうございます。設定の方を見ずにtomcatが悪いと思い込んでました。設定の方をよく見て設定してみたいと思います。

— セッキー (@sekki_net) 2015, 11月 14

@sekki_net いや tomcatとかmysqlとかそっちかもしれません。よく考えたら、この設定はデフォルトで無効になってました。

— giraffeforestg (@giraffeforestg) 2015, 11月 14

@giraffeforestg tomcatとかmysqlの場合どんな対策を取れば良いのでしょうか？…

@sekki_net その他参考： Performance Test Execution for 4.2 https://t.co/r1QXUrXoNq

とのことなので、Performance Test Execution for 4.2 – Apache Cloudstack – Apache Software Foundationを見ながらチューニング

とりあえず、MySQLから
MySQLTunerを使い基本的なチューニング

    query_cache_size (>= 8M)
    join_buffer_size (> 128.0K, or always use indexes with joins)
    thread_cache_size (start at 4)
    table_open_cache (> 64)
    innodb_buffer_pool_size (>= 506M) if possible.
    innodb_log_buffer_size (>= 1M)

MySQLTunerの結果を見つつwikiに乗ってるmy.cnfをにらめっこしつつ設定を変えてく

一部抜粋

innodb_buffer_pool_size = 1024M
innodb_log_buffer_size = 4M
key_buffer_size = 512M
max_allowed_packet = 1M
table_open_cache = 512
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M

slow_query_log_file = /var/lib/mysql/slow-queries.log
long_query_time = 5
max_heap_table_size = 2048M
query_cache_size = 0
thread_cache_size = 4

あとはtomcatのチューニング
どこ変更したか覚えてないので何となくで書きます…
/etc/cloudstack/management/tomcat6.conf
JAVA_OPTS の -Xms2g -Xmx4g とか　 -XX:PermSize=1024m -XX:MaxPermSize=1024m とか追加した気がします
/etc/cloudstack/management/server-nonssl.xml のなかのmaxThreadsとか変更しました

【java　チューニング】とか【tomcat　チューニング】でググッて出てきたのを変更しました

設定変更後

service cloudstack-management restart

でcloudstackを再起動させて起動確認

@giraffeforestg 色々弄った結果無事動きました！ありがとうございます！

@sekki_net おお！おめでとうございます！よろしければ以下への参加もどうぞ。数行の感想でもok https://t.co/2n3kYLUxJM

結果
一斉にインスタンスを作ると【インスタンスの作成エラー】的なエラーが出るものの、インスタンス一覧の画面に戻るときちんと作成されてました。
一斉にインスタンスが作れるのを確認できたのでおｋとしました。

時間がなく「今この値で動かないからこんぐらいにしとけば動くだろう」って言う感じのチューニングでしたが、
次はちゃんとログなどにらめっこしつつ論理的にチューニングしていきたいです。（小並感

Raspberry Pi 2 Model B にPidora入れたかった

Raspberry Pi 2 Model B にPidora入れてUSBケーブル挿したけど赤いLEDがついただけだった
raspbian見たいにダウンロードして書き込めばいいのかなーっと思ったけど何故か動かなかった

USBケーブル指しても赤いLEDが付くだけ
何でだろう、そのうち調べてみます。（とりあえず、記事書くって言う意思表示）
バージョンはPidora-2014-R3です

XenServerに物理ハードディスクを追加してみた – yoshida_eth0の日記　http://d.hatena.ne.jp/eth0jp/20100614/1276454721

要するに

/dev/sdb1と
Local storage 2を変えればおｋ

XenCenterを見るとLocal storage 2が追加されてる

コマンドを入力する左側の表示を変更する

投稿日時: 2014年7月27日投稿者: sekki

返信

前回、さくらレンタルサーバーでcshからbashに変更しました。

変更したのはいいが、コマンドを入力する左側（名前わかんない）がディレクトリ移動する度に増えてくという仕様になっているので変更していきます。

現在こんな感じ

[ユーザー名@サーバー名 ~/www/sekki/hoge/fuga/ber（まだまだ増えるよ！）]$

左側の表示する方法の環境変数を確認

$ echo $PS1
[\u@\h \w]\$

変更

$ export PS1='[\u@\h \W]:\!$ '

現在居るディレクトリ名だけ表示される
メデタシメデタシ

[ユーザー名@サーバー名 ber]:51$

一々打つのめんどいので.bashrcに書き込む

echo "export PS1='[\u@\h \W]:\!$ '" >> ~/.bashrc

以上！

詳しくは　第8回：環境設定を変更してみる！ | ConoHa　http://www.conoha.jp/conoha/learning/1748.html　ここを参考に
