Title:
[NFS] Nova raises error on server resize command
Status in Cinder:
New
Status in OpenStack Compute (nova):
New
Bug description:
[env] devstack
[OS] Ubuntu 20.04.4 LTS
[driver] generic-nfs
Nova raises error when changing the parameters of the instance and
connected disk with the type volume generic-nfs.
Execution steps for this case:
1. Create a new volume with image and with type generic-nfs
2. Create a new instance with boot volume.
3. Do something interactive with the guest like get its console output.
4. Modify server disk and RAM to other provided flavor via openstack cli "server resize --flavor FLAVOR INST"
