Mounting GPFS remote mount on compute nodes

Learn how to mount a remote GPFS filesystem into compute nodes.

After an IBM Storage Scale cloud cluster is deployed for the first time by using the ./cloudkit create cluster command, the GPFS remote mount does not get mounted on a compute node from a storage node by default.

You must explicitly mount a GPFS file system on a compute node by using the cloudkit grant filesystem command.

Before you run the cloudkit grant filesystem command, make sure that both storage and compute nodes were created in the IBM Storage Scale cloud cluster environment.

To mount a GPFS file system on compute nodes, enter the following command:

#./cloudkit grant filesystem

Example:

#./cloudkit grant filesystem
