Upgrading NFS packages

Use these steps on each protocol node one by one to upgrade IBM Spectrum Scale NFS packages.

Attention:

All protocols must also be upgraded to the newer code level along with base GPFS.
After you upgrade from an earlier version to the current version, it might be necessary to unmount and mount the file system on the NFS clients to ensure continued access.

Suspend the node by issuing the following command.
```
mmces node suspend --stop
```
Note: Suspending nodes triggers IP address reassignment and client failover.
Upgrade NFS packages on the node by issuing one of the following commands depending on the operating system.
- For Red Hat Enterprise Linux and SLES, issue the following command.
```
rpm -Uvh NFS_Package_Name1 NFS_Package_Name2 ... NFS_Package_NameN
```
- For Ubuntu, issue the following command.
```
apt-get install ./NFS_Package_Name1 ./NFS_Package_Name2 ... ./NFS_Package_NameN
```
  For a list of packages for the current IBM Spectrum Scale release, see Manually installing the IBM Spectrum Scale software packages on Linux nodes.
Resume the node by issuing the following command.
```
mmces node resume --start
```
