GlusterFS : ノードを追加する2023/06/19 |
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。 |
