Enabling the Platinum Posix Client for Kubernetes Interfaces for Data Fabric FlexVolume Driver

When you install the Kubernetes Interfaces for Data Fabric FlexVolume Driver, the Basic FUSE-based POSIX client package is installed on all nodes by default. The FlexVolume Driver also supports the use of the Platinum FUSE-based POSIX client. For a comparison of the two POSIX client packages, see Preparing for Installation (HPE Ezmeral Data Fabric POSIX Client).

To install the Platinum POSIX client, include the platinum parameter in your Pod spec. For example:

options:
cluster: "cluster2"
platinum: "true"
cldbHosts: "10.10.102.96"
