Installing Cluster Export Services as part of installing IBM Spectrum Scale on Linux systems

Use this information to install Cluster Export Services (CES) on Red Hat Enterprise Linux 7.x, SLES 12, and Ubuntu 16.04 LTS and 18.04 LTS systems.

Note:

The object protocol is not supported on SLES 12.
SMB, NFS, and object protocols are not supported on the s390x architecture.

Important: If you plan to install and configure CES, all protocols available on your platform must be installed. Installing a subset of available protocols is not supported.

Unmount GPFS file systems and stop GPFS on all nodes using the following command.
```
# mmshutdown -a
```
Configure the CES shared root file system on one of the available file systems using the following command.
```
# mmchconfig cesSharedRoot=/gpfs/fs0
```
Start GPFS on all nodes in the cluster using the following command.
```
# mmstartup -a
```
Enable CES on the required nodes using the following command.
```
# mmchnode -–ces-enable –N prnode1,prnode2,prnode3
```

Add the IP addresses of the protocol nodes to CES using the following commands.

# mmces address add --ces-ip 198.51.100.2
# mmces address add --node prnode1 --ces-ip 198.51.100.2

Verify the CES configuration using the following commands.
```
# mmlscluster --ces
# mmces address list
```

At this point, there are no services enabled. You can verify that using the mmces service list --all command. The system displays output similar to the following.

No CES services are enabled.
