仮想マシンでCentOS7.5をQoreStor Community Edition用にセットアップしてみよう

＞＞前提条件

　 QoreStorのレポジトリ用ディスク領域とメタデータ用ディスク領域を準備
ファイルシステムはXFS
マウントする際にnoatime,nofail,dirsyncのオプションを設定
パッケージとしてnfs-utilとpolicycoreutilsが必要

＞＞QoreStorの無料Communityエディション用に仮想マシンをセットアップし、CentOS7.5をインストールします 

 （１）

QoreStorの動作要件を満たす仮想マシンを作成し、CentOSをインストールします

CPU：        4コア以上
メモリー：　14GB以上
ディスク：　/dev/sda 50GB OS用
                     /dev/sdb 500GB メタデータ用
                     /dev/sdc 1000GB レポジトリ用




NFS用パッケージが必要です。
 （２）

OSインストール後の設定
必要なパッケージの確認
