Enabling NFS, SMB, HDFS, and S3 on Linux systems

Use this information to enable NFS, SMB, HDFS, and S3 on Linux® systems after installing the packages.

Before you begin enabling NFS, SMB, HDFS, and S3, you must have installed the corresponding IBM Storage Scale packages.

For HDFS, follow the instructions in Enable and Configure CES HDFS under IBM Storage Scale support for Hadoop in Big data and analytics support.

Enable NFS as follows:
1. If the kernel NFS service is running, mask and stop the kernel NFS service on all nodes where CES NFS needs to be installed by using the following commands:
```
# systemctl mask nfs-server.service
# systemctl daemon-reload
# systemctl stop nfs
```
2. Enable the NFS services by using the following command:
```
# mmces service enable NFS
```
  If you get the /sbin/rpc.statd: not found [No such file or directory] error, try the following workaround.
  
  Run the following commands on every protocol node.
```
# ln -s /usr/sbin/rpc.statd /sbin/rpc.statd
# ln -s /sbin/rpcinfo /usr/sbin/rpcinfo
```
  After you have run these commands, try enabling the NFS services again.
Enable the SMB services by using the following command:
```
# mmces service enable SMB
```
Enable the S3 services by using the following command:
```
# mmces service enable S3
```
