NFS Quick Reference Points
The cluster head node exports an NFS, compute nodes import NFS on the head node. The cluster
comes with a pre-configured NFS mount. The headnode exports the /data filesystem. The
compute nodes mount head node /data1 on /cluster.
You need to execute the following commands to export a filesystem via NFS from the head node:
# platformmanage-cli addnfsexport <head_node> <filesystem>
# /etc/init.d/scance restart
To import this filesystem on a particular compute node:
# platformmanage-cli addremotefs compute_node nfs
head_node:/filesystem mount_point
# platformmanage-cli reconfigure compute_node
If the compute nodes need to mount filesystems located outside the cluster, then NAT must be
enabled on the head node. You need to execute the following commands on the head node:
# platformmanage-cli addnatservice head_node ethernet_dev
# /etc/init.d/scance restart
Now you can access nodes outside the cluster from your compute nodes.
To mount a remote filesystem residing outside the cluster on a particular compute node you need
to do the following:
# platformmanage-cli addremotefs compute_node nfs
external_node:/filesystem mount_point
# platformmanage-cli reconfigure compute_node
