Open Stack

Hello, Grigoriy

One or more of following requirements are not met in your case:

1) Generic driver should be configured to use
"driver_handles_share_servers=False" mode.
2) Share type "my_share_type" should contain extra spec
"driver_handles_share_servers=False",
same as for (1)
3) Your NFS server should be in Nova VM and this Nova VM should be enabled
in manila configuration for generic driver (1).
