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

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。
（追記）v5.1.0以降をインストールする場合、GNOME DesktopなどのGUIは選択しないでください。

OSインストール後の設定
必要なパッケージnfs-utilおよびpolicycoreutilsの確認

[root@qsschool5  ~]# rpm -qa | grep nfs-util
nfs-utils-1.3.0-0.54.el7.x86_64

[root@qsschool5  ~]# rpm -qa | grep policycoreutils
policycoreutils-2.5-22.el7.x86_64
policycoreutils-python-2.5-22.el7.x86_64

（v5.1.0～）v5.1から、samba4とlibwbclientは削除する必要があります

[root@qsschool5 ~]# rpm -qa | grep samba
