ComicCafe: NASの自作 Part45

前回、Adaptec ASA-6805Hのファームウェアをアップデートした後に、Windows10が激遅になった問題ですが、記憶域スペースを削除することで解消しました。記憶域スペースに対する書き込みがあまりの遅いため、それに引きずられる形でWindowsが遅くなっていたのかもしれません。今日はOMVを再インストールしました。再インストールから設定の手順を通しでメモ書きしておきます。手順14を追加したことで最初のRAID構築の速度がかなり改善しました。

09. 各種ツールをインストール

apt-get update
# exFATをマウントできるようにする
apt-get install exfat-fuse exfat-utils
# unzipのインストール
apt-get install unzip
# Javaのインストール
apt-get install openjdk-7-jre
# vimのインストール
apt-get install vim vim-common
cp /usr/share/vim/vimrc ~/.vimrc
# syntax on を追記
vim ~/.vimrc

10. Adaptec ASA-6805Hのドライバのインストール

apt-get install linux-headers-$(uname -r) build-essential
apt-get install dkms
wget http://download.adaptec.com/sas/linux/adp80xx_linux_drivers_v1.2.0-10624.tgz
tar zxvf adp80xx_linux_drivers_v1.2.0-10624.tgz
cd debian_7.2/x64/
dpkg -i pm80xx-1.2.0-10624-debian64.deb
apt-get -f install
reboot

11. S.M.A.R.Tの有効化

12. 通知メール設定

13. WOLの有効化

ethtool -s eth0 wol g

14. RAID構築のパフォーマンスチューニング

# /etc/sysctl.conf に以下の2行を追加。この設定でRAIDの構築時間を短縮できます
dev.raid.speed_limit_min = 50000
dev.raid.speed_limit_max = 5000000

15. RAIDの構築

16. RAIDの状態を確認(メモっておいたほうが良さげ)

# cat /proc/mdstat

17. ファイルシステムの作成(EXT4)

18. ファイルシステムをマウント

19. 起動時にRAIDを再構築するスクリプトを配置(SASカードの認識が遅く起動時のRAID構築に失敗する為)

20. 共有フォルダの作成

21. SMB/CIFSの設定

22. Sambaのチューニング

max protocol = SMB2
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=87600 SO_RCVBUF=87600

23. RAIDのチューニング

# /etc/rc.localに追加
echo 32768 > /sys/block/md0/md/stripe_cache_size
