Adding and removing NFS storage

Add external NFS storage to Integrated Analytics System.

Before you begin

Prior to adding or removing external storage to the appliance, the system state must be stopped. The code will check to ensure the appliance is in the proper state prior to executing. The appliance can be put into the proper state by running the apstop command.

About this task

Adding NFS storage

To add NFS, you need to log in to node0101 from the command prompt.

When logged in, type the following command and provide required information:
Note:
  • The NFS server that you provide must allow the IAS access. If you choose Selection 1, ensure that your system is on the AuthorizedClients list.
  • You can specify your custom mount point using the last available selection after the auto-detected mounts. However, it is recommended to enable showmount as there is no guarantee that the custom mounts will work.
storage_setup -e nfs
See /var/log/appliance/platform/xcat/setup_storage.log to watch its progress.
