Creating and configuring file systems and filesets for exports

If you have not done so, create the file systems and the filesets for the data to be exported through the protocol services. For more information, see mmcrfs command and mmcrfileset command.

Creating a fileset through the GPFS GUI

To create a fileset, log on to the IBM Storage Scale GUI and select Files > Filesets > Create Fileset.

IBM® strongly recommends that you configure the file systems to allow only NFSv4 ACLs through the -k nfs4 option for mmcrfs. For using SMB and NFS CES protocol access, configuring the file system with -k nfs4 is required. When you use the default configuration profiles (/usr/lpp/mmfs/profiles) that are included with IBM Storage Scale, the NFSv4 ACL setting is already set from the profile configuration (see Authorizing file protocol users for details). Also, if quotas must be used, enable the quota usage during the file system creation.

For information on unified file and object access, see Planning for unified file and object access.

If you are using HDFS, see the multi-protocol limitation under Hadoop ACL and IBM Storage Scale protocols in IBM Spectrum® Scale Big Data and Analytics Support documentation.

Note: Ensure that all GPFS file systems used to export data via NFS are mounted with the syncnfs option in order to prevent clients from running into data integrity issues during failover. It is recommended to use the mmchfs command to set the syncnfs option as default when you mount the GPFS file system.
