Container Storage Interface (CSI) Storage Plugin Release 1.2.x (FUSE POSIX)

New in this Release

With the FUSE 1.2.11 and Loopback NFS 1.0.11 plugins, snapshot restore to new volumes uses Data Fabric mirroring functionality to restore the volumes. This works only with Data Fabric 6.2.0.10 and higher. For older core versions, the restoreMethod: "snapshot" parameter must be passed in the StorageClass parameters section.

You can access the csi-kdfplugin by installing the custom resource definition (CRD) using the csi-maprkdf-v<version>.yaml file. Or you can build your own container and point to the plugin on the Docker hub at maprtech/csi-kdfplugin:<version>. For installation information, see Installing, Uninstalling, and Upgrading the Container Storage Interface (CSI) Storage Plugin.

Patches

None.

Limitations

Note the following limitations:

• CSI Driver version 1.2.x does not support coexistence with the FlexVolume Driver on the same Kubernetes cluster.
• All nodes in the Kubernetes cluster must use the same Linux OS. Configuration files are available to support the following Linux distributions:
  • CentOS
  • RHEL (use CentOS configuration file)
  • Ubuntu
• The Container POSIX client package is included by default when you install the Container Storage Interface (CSI) Storage Plugin. The Basic, Container, or Platinum POSIX client can be enabled by specifying a parameter in the pod spec.
• The CSI Driver does not include support for inline volumes in pods. It supports only PersistentVolumes.

Known Issues

Note the following known issues:

• On FUSE 1.2.10 and older or LoopbackNFS 1.0.10 and older, snapshot restore fails if the snapshot contains symlinks to other files in the directory.

  If your cluster is installed with Data Fabric 6.2.0.10 or higher, use the restoreMethod: "mirror" in StorageClass parameters.
