Adding space management to an exported file system

Edit online

HSM supports only the NFS (Network File System) interface to export a file system.

Before you begin

When you access the HSM-managed file system by using NFS, set the dmapiEventTimeout option of GPFS to a finite value of some seconds. The option is changed by using mmchconfig, for example: /usr/lpp/mmfs/bin/mmchconfig dmapiEventTimeout=1000

About this task

To add space management to a file system that the NFS server exports, follow these steps:

Procedure

  1. Instruct all NFS clients to unmount the exported file system.
  2. To view which clients mounted the exported file system, issue the following command:
    /usr/sbin/showmount -a.
  3. Add space management to your file system using the dsmmigfs add command.
  4. To export the NFS file system again, issue the following command:
    /usr/etc/exportfs -a .
  5. Instruct all NFS clients to mount the exported NFS file system again.
