Password-less authentication configuration The best practice is to configure password-less authentication between all nodes. Generate the public-keys using the ssh-Keygen command. Use the mmchcluster command to set node2 as the secondary configuration server. Create the NSDs using the mmcrnsd command. This is an asynchronous process. GPFS cluster configuration servers:

All nodes host names should be resolved from each and every node.
Create a file system using the mmcrfs command. Create the NSDs using the mmcrnsd command. A shared disk cluster is the most basic environment. Check the status of the cluster using the mmgetstate command.

IBM GPFS cluster installation and configuration in IBM AIX
Command successfully completed mmchlicense: GPFS cluster configuration servers: The key fingerprint is: GPFS provides concurrent high-speed file access to the applications executing on multiple nodes of clusters which can be used with AIX 5L, Linux, and Windows platforms.
Use the mmgetstate command to verify that both nodes are in the active state.
Confirm that the node has been added to the cluster using the mmlscluster command. Propagating the cluster configuration data to all affected nodes. This section explains how to configure gpfe password-less authentication with an example.
Verifying the GPFS installation
Processing node node1 mmcrcluster: This node does not belong to a GPFS cluster. Perform the same steps across all nodes. Use the mmchlicense command to designate licenses as needed. Password-less authentication configuration The best practice is to configure password-less authentication between all nodes.

Else, you can also use the following command:. Event Thembisa school collaborate FinChatbot September 19, Operating system level configuration All nodes host names should be resolved from each and every node.
Examine previous error messages to determine cause. Set the license mode for the node using the mmchlicense command. Generate the public-keys using the ssh-Keygen command. Use the mmdf command to get information on the file system. Apply the GPFS license on the primary node using the mmchlicense command. Use the mmchcluster command to set node2 as the secondary configuration server.
The GPFS is a high-performance clustered file system that can be deployed in shared-disk or shared-nothing distributed parallel modes. Verify that the file system has been created correctly using the mmlsfs command. Enter passphrase empty for no passphrase: The file system will be available automatically on both the systems. Mount the file system using the mmmount command. Configure the cluster primary node using the mmcrcluster command.
Event Soweto school-in collaboration with FinChat September 17, Verify that the file system is mounted using the df command.
