On this issue kubernetes/cloud-provider-openstack#1315, there is the following link to the multi-attach doc, but it is on someone's private repo? Is it somewhere in a merged official doc? Also in the multi-attach doc, it uses CSC tools from gocsi which is no longer supported. Do you have plan to use a different tool?

The official docs do mention multi-attached cinder volumes.

https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/cinder-csi-plugin/features.md#multi-attach-volumes

The official documentation is lacking on how one creates these. https://docs.openstack.org/cinder/latest/admin/volume-multiattach.html does go into more details with the cinder cli.

I hadn't noticed that the link in that GH issue was on a fork of the docs. I'll switch to the official docs.

Thanks Xing.
