Hi,
I am looking for instructions on how to configure a Manila service with Cinder as a backend. I have gone through the https://github.com/openstack/manila/blob/master/doc/source/configuration/sha... page, and I am wondering if someone has a link to a preconfigured "golden image" that can be used as a service_image.
As for the image to be used as a service image, we usually use [1] on CI. It is a Ubuntu 22 image with minimal things installed. You would need to create a Glance image with this image and then add the service image name to your Manila.conf in case you are deploying with driver_handles_share_servers=True (DHSS=True). Or in case you want to use DHSS=False, you will need to create the VM and add the instance name or ID to the manila.conf. The admin guide for Manila has instructions for both approaches [2].
Additionally, I am wondering if this configuration can be used with driver_handles_share_servers=True (generally, I see that both options are supported here), but are there any specific limitations?
Yes, you can use this configuration with DHSS=True. There are known restrictions documented here [3].
I have already configured other backends (standalone ZFS, NFS, and Huawei driver), but I would like to test share snapshot retrieval using Cinder as a backend. Unfortunately, as I see, Cinder is not as straightforward as other backends(or no one is using it), which is why I am asking for some hints.
The Generic driver is mostly used for testing on CI. We are aware of people using it in production environments but it's not something we recommend. You should be able to create and delete snapshots using the Generic driver, as well as create shares from snapshots. Reverting to snapshots is not something available, as per the feature support mapping [4].
Thanks in advance /Jan
