OpenStack Integration

Info

This driver is still not part of the official OpenStack support matrix.

We are working on getting it there.

Features Supported

The following list of features is supported: - Thin provisioning - Creating a volume - Resizing (extend) a volume - Deleting a volume - Snapshotting a volume - Reverting to snapshot - Cloning a volume (copy-on-write) - Extending an attached volume - Multi-attaching a volume - Volume migration (driver-supported) - QoS - Active/active HA support

Deployment

Depending on the fabric, it is necessary to load the Linux kernel modules on compute nodes and controller:

Load NVMe/TCP on Ubuntu or Debian

sudo apt-get install -y linux-modules-extra-$(uname -r)
sudo modprobe nvme_tcp

Load NVMe/TCP on RHEL, Rocky or Alma

sudo modprobe nvme_tcp

In case you need the RoCE/RDMA fabric or both fabrics, (also) run:

Load NVMe/RoCE on Ubuntu or Debian

sudo apt-get install -y linux-modules-extra-$(uname -r)
sudo modprobe nvme_rdma

Load NVMe/RoCE on RHEL, Rocky or Alma

sudo modprobe nvme_rdma

Update globals.yaml

enable_cinder: "yes"
...
#This is a fork of the cinder-volume driver container including Simplyblock:
cinder_volume_image: "docker.io/simplyblock/cinder-volume"
#If Simplyblock is the only Cinder Storage Backend:
skip_cinder_backend_check: "yes"

Update Cinder Override for Simplyblock Backend Located in /etc/kolla/config/cinder.conf

[DEFAULT]
debug = True
# Add Simplyblock to enabled_backends list
enabled_backends = simplyblock

[simplyblock]
volume_driver = cinder.volume.drivers.simplyblock.driver.SimplyblockDriver
volume_backend_name = simplyblock
simplyblock_endpoint = <simplyblock_endpoint>
simplyblock_cluster_uuid = <simplyblock_cluster_uuid>
simplyblock_cluster_secret = <simplyblock_cluster_secret>
simplyblock_pool_name = <simplyblock_pool_name>

Rerun Kolla-Ansible Deploy Command for Cinder

kolla-ansible deploy -i <inventory_file> --tags cinder
