With "manila pool-list --detail", you are able to see the backend's capabilities. You would use this information to create share types. The share type you're using needs to have the extra-spec "snapshot_support=True". Without it, shares created of that type will not support snapshots.

When administrators do not set this capability as an extra-spec in a share type, the scheduler can place new shares of that type in pools without regard for whether snapshots are supported, and those shares will not support snapshots.
