Migrating to GPFS 3.2 from GPFS 3.1
GPFS V3.2.1 Concepts, Planning, and Installation Guide
GA76-0413-02
GPFS™ 3.2 supports node-at-a-time migration if the previous nodes in the cluster are running GPFS 3.1. GPFS 3.1 nodes can coexist and interoperate with nodes running GPFS 3.2. However, some new functions (such as creating a GPFS file system to be mountable on Microsoft® Windows® , that depend on format changes will not be available until all nodes have been migrated.
To migrate a cluster to GPFS 3.2 from GPFS 3.1, perform these steps:
Stop all user activity in the file systems on the designated node.
Cleanly unmount the mounted GPFS file system. Do not use force unmount on the designated node.
Follow any local administrative backup procedures to ensure protection of your file system data in the event of a failure.
Stop GPFS on the node to be migrated in the cluster, for example:
mmshutdown -N k164n04Copy the installation images and install the new code on each node in the cluster as described in Installing GPFS on Linux nodes or Installing GPFS on AIX nodes.
Start GPFS on the designated node in the new cluster, for example, issue:
mmstartup -N k164n04Mount the file systems if this is not done automatically when the GPFS daemon starts. |
