About zfssa-cs-driver
This plugin supports Oracle ZFS Storage Appliance as a backend for block storage (iSCSI volumes) and file storage (NFS).
| CSI Plugin Version | Supported CSI Versions | Supported Kubernetes Versions | Persistence | Supported Access Modes | Dynamic Provisioning | Raw Block Support |
|---|---|---|---|---|---|---|
| v0.5.x | v1.0+ | v1.17.X+ | Persistent | Read/Write Once (for Block) | Yes | Yes |
Requirements
- Kubernetes v1.17 or above.
- A Container runtime implementing the Kubernetes Container Runtime Interface. This plugin was tested with CRI-O v1.17.
- An Oracle ZFS Storage Appliance running Appliance Kit Version 8.8 or above. This plugin may work with previous versions but it is not tested with them. It is possible to use this driver with the Oracle ZFS Storage Simulator
- Access to both a management path and a data path for the target Oracle ZFS Storage Appiance (or simulator). The management and data path can be the same address.
- A suitable container image build environment. The Makefile currently uses docker but with minor updates to release-tools/build.make, podman should also be usable.
Unsupported Functionality
ZFS Storage Appliance CSI driver does not support the following functionality:
- Volume Cloning
Building
Use and enhance the Makefile in the root directory and release-tools/build.make.
make
Installation
See INSTALLATION for details.
Testing
For information about testing the driver, see TEST.
Examples
Example usage of this driver can be found in the ./examples directory.
The examples below use the image container-registry.oracle.com/os/oraclelinux:7-slim when they create a container where a persistent volume(s) is attached and mounted.
This set uses dynamic volume creation.
- NFS - illustrates NFS volume usage from a simple container.
- Block - illustrates block volume usage from a simple container.
- NFS multi deployment - illustrates the use of Helm to build several volumes and optionally build a pod to consume them.
This next set uses existing shares on the target appliance:
- Existing NFS - illustrates NFS volume usage from a simple container of an existing NFS filesystem share.
- Existing Block - illustrates block volume usage from a simple container of an existing iSCSI LUN.
This set exercises dynamic volume creation followed by expanding the volume capacity.
- NFS Volume Expansion - illustrates an expansion of an NFS volume.
This set exercises dynamic volume creation (restoring from a volume snapshot) followed by creating a snapshot of the volume.
- NFS Volume Snapshot - illustrates a snapshot creation of an NFS volume.
- Block Volume Snapshot - illustrates a snapshot creation of a block volume.
