File systems and NFS Exports overview

While creating File Systems and NFS Exports, it is helpful to note the following:

• A NAS server must be configured to support NFS protocol before creating a file system.

• You can choose to add NFS Exports the first time you create the file system, or you can add NFS Exports to a file system after it has

been created.

Create a file system for NFS exports

You can create a file system for NFS exports.

Prerequisites

Make sure that there is a NAS server that is configured to support the NFS protocol.

Steps

1. Select Storage > File Systems.

2. Click Add.

The Add File System wizard launches.

3. Select an NFS enabled NAS server for the file system.

4. Specify the file system details, including the file system name and size, minimum size is 3 GB, maximum size is 256 TB.

NOTE:

All thin file systems, regardless of size, have 1.5GB reserved for metadata upon creation. For example, after

creating a 100GB thin file system, PowerStore T model immediately shows 1.5GB used. When the file system is

mounted to a host, it shows 98.5GB of usable capacity.

This is because the metadata space is reserved from the usable file system capacity.

5. Configure the initial export for the file system.

NOTE: You can add NFS exports to the file system at later time.

6. Configure security, access permissions, and host access for the system.

Security

Select Sys to allow users with non-secure NFS, or Secure NFS to mount and NFS export on the file system. If you

are not configuring Secure NFS you must select this option.

If you are creating a file system with Secure NFS, then you can choose from the following options:

• Kerberos to allow any type of Kerberos security for authentication (krb5/krb5i/krb5p).

• Kerberos with Integrity to allow both Kerberos with integrity and Kerberos with encryption security for user

authentication (krb5i/krb5p).

• Kerberos with Encryption to allow only Kerberos with encryption security for user authentication (krb5p).

Default Access The default access that is applied to the hosts unless the hosts are configured with a different access permission.
