Redhat build RHCS and shared storage

 

Use the Redhat Rhcs suite to build a high-availability cluster, and bind it to implement iscsi network storage!

The extension diagram is as follows:

After the logical volume is created, both nodes will display the volume group and logical volume information, if no node is displayed, type service clvmd restart! 2. To set the GFS file system, you must create cluster1 and add the node. Otherwise, the system prompts that the clvmd service does not exist!
