怎么查看linux下rhcs文件系统

clustat

cman_tool status

cman_tool nodes -a

下面是这些命令查询的显示结果示例：

#1.1 clustat查看集群状态（最常用）

在节点1查看的，状态中的Local就在节点1上显示。

# clustat

、建立集群

3.1.1

、创建集群文件系统

node1

mmcrcluster -n /tmp/gpfs_node -p node1 -s node2 -r /usr/bin/ssh -R /usr/bin/scp

命令显示：

mmcrcluster: Processing node 1

mmcrcluster: Processing node2

mmcrcluster: Command successfully completed

mmcrcluster: Propagating the cluster configuration data to all affected nodes.

This is an

asynchronous process.
