Hi Nehal, Yes, a volume can be attached with VNF for persistent storage. Please see for detail reference. [1]: https://github.com/openstack/tacker/blob/master/doc/source/reference/block_s...

For this, I wanted to create a persistent volume such that if a VNF gets deleted and a new one gets launched, it can access the data created by the previous VNF. Is there a way to do this? Thanks.
