GlusterFS 8 : ノードを追加する2021/04/05 |
|
既存のクラスターにノードを追加する場合の設定です。
例として、リンク先の通り構築した分散構成のクラスターに [node03] を新規に追加します。
|
+----------------------+ | +----------------------+
| [GlusterFS Server#1] |10.0.0.51 | 10.0.0.52| [GlusterFS Server#2] |
| node01.srv.world +----------+----------+ node02.srv.world |
| | | | |
+----------------------+ | +----------------------+
⇑ | ⇑
file1, file3 ... | file2, file4 ...
|
+----------------------+ |
| [GlusterFS Server#3] |10.0.0.53 |
| node03.srv.world +----------+
| |
+----------------------+

こちらを参考に、新規ノードに GlusterFS サーバーをインストールして起動し、
既存ノードと同様のパスに GlusterFS ボリューム用のディレクトリを作成しておきます。
|
| [2] | 既存ノードのいずれかのノードで、新規ノード追加の設定をします。 |
