Make sure that there is a NAS server that is configured to support the NFS protocol.
Steps
Select
File > File Systems.
Click
Create.
The
Create File System wizard launches.
Select an NFS enabled NAS server for the file system.
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, the system 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.
Configure the initial export for the file system.
NOTE:You can add NFS exports to the file system at later time.
Configure security, access permissions, and host access for the system.
Option
Description
Minimum 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.
Add Host
Enter hosts individually, or you can add hosts by uploading a properly formatted CSV file. You can download the CSV file first to obtain a template.
Option
Description
Local path
The path to the file system storage resource on the storage system. This path specifies the unique location of the share on the storage system.
Each NFS share must have a unique local path. PoweFlex automatically assigns this path to the initial export created within a new file system. The local path name is based on the file system name.
Before you can create more exports within an NFS file system, create a directory to share from a Linux/UNIX host that is connected to the file system. Then you can create an export from PowerFlex Manager and set access permissions accordingly.
Export path
The path used by the host to connect to the export. PowerFlex creates the export path that is based on the IP address of the host, and the name of the export. Hosts use either the file name or the export path to mount or map to the export from a network host.
Optionally, add a protection policy to the file system.
If you are adding a protection policy to the file system, the policy must have been created before creating the file system. Only snapshots are supported for protection for file systems. Replication is not supported on file system.
Review the summary and click
Create File System.
The file system is added to the
File System tab. If you created an export simultaneously, then the export displays in the
NFS export tab.
