It is not possible to mount a NFS volume created through manila-ganesha on an openstack VM. Below mount command from the openstack VM is timing out:

$ mount -t nfs [2620:cf:cf:aaaa::2]:/volumes/_nogroup/53f1bea2-5ae5-4546-b223-27d68a92bf39/2f1db671-0407-4e5e-b42d-f75ac68ba3d0 /tmp/mnt/ 

 
It looks like the ganesha container is not going up correctly. There's no process listening on port 12049 in the compute-0 with HCI, so the NFS haproxy is reachable, but the ganesha isn't:

[root@compute-prmyjj9s-0 ~]# netstat -tulnp | grep 2049 
tcp6 0 0 2620:cf:cf:aaaa::2:2049 :::* LISTEN 3686/haproxy

 
Comparing to ipv4 setup:
 

[root@compute-15pn0hyq-1 ~]# netstat -tulnp | grep 2049 
tcp 0 0 192.168.122.2:2049 0.0.0.0:* LISTEN 16692/haproxy 
tcp6 0 0 :::12049 :::* LISTEN 16361/ganesha.nfsd 
udp6 0 0 :::12049 :::* 16361/ganesha.nfsd

To Reproduce

1. Install osasinfra-ipv6 DT. 
2. Create a VM
3. Create a manila share
4. Mount the share from the VM, for example:

mount -t nfs [2620:cf:cf:aaaa::2]:/volumes/_nogroup/53f1bea2-5ae5-4546-b223-27d68a92bf39/2f1db671-0407-4e5e-b42d-f75ac68ba3d0 /tmp/mnt/ 

Expected behavior

• The NFS volume can be mounted on the VM

Screenshots

• N/A
