Hitachi NAS Platform File Services Driver for OpenStack
Overview
The Hitachi NAS Platform File Services Driver for OpenStack provides NFS Shared File Systems to OpenStack.
Requirements
- Hitachi NAS Platform Models 3080, 3090, 4040, 4060, 4080, and 4100.
- HNAS/SMU software version is 12.2 or higher.
- HNAS configuration and management utilities to create a storage pool
(span) and an EVS.
- GUI (SMU).
- SSC CLI.
Supported shared filesystems and operations ------------------------------------------The driver supports CIFS and NFS shares.
The following operations are supported:
- Create a share.
- Delete a share.
- Allow share access.
- Deny share access.
- Create a snapshot.
- Delete a snapshot.
- Create a share from a snapshot.
- Extend a share.
- Shrink a share.
- Manage a share.
- Unmanage a share.
Preparation and Deployment
Note
The manila-share node only requires the HNAS EVS data interface if you plan to use share migration.
It is mandatory that HNAS management interface is reachable from the Shared File System node through the admin network, while the selected EVS data interface is reachable from OpenStack Cloud, such as through Neutron flat networking.
Configuration on Kolla deployment
Enable Shared File Systems service and HNAS driver in
/etc/kolla/globals.yml
enable_manila: "yes"
enable_manila_backend_hnas: "yes"Configure the OpenStack networking so it can reach HNAS Management interface and HNAS EVS Data interface.
To configure two physical networks, physnet1 and physnet2, with ports eth1 and eth2 associated respectively:
In /etc/kolla/globals.yml set:
neutron_bridge_name: "br-ex,br-ex2"
neutron_external_interface: "eth1,eth2"Note
eth1: Neutron external interface. eth2: HNAS EVS data interface.
HNAS back end configuration --------------------------
In /etc/kolla/globals.yml uncomment and set:
hnas_ip: "172.24.44.15"
hnas_user: "supervisor"
hnas_password: "supervisor"
hnas_evs_id: "1"
hnas_evs_ip: "10.0.1.20"
hnas_file_system_name: "FS-Manila"Configuration on HNAS
Create the data HNAS network in Kolla OpenStack:
List the available tenants:
$ openstack project listCreate a network to the given tenant (service), providing the tenant ID, a name for the network, the name of the physical network over which the virtual network is implemented, and the type of the physical mechanism by which the virtual network is implemented:
$ neutron net-create --tenant-id <SERVICE_ID> hnas_network \
--provider:physical_network=physnet2 --provider:network_type=flatOptional - List available networks:
$ neutron net-listCreate a subnet to the same tenant (service), the gateway IP of this subnet, a name for the subnet, the network ID created before, and the CIDR of subnet:
$ neutron subnet-create --tenant-id <SERVICE_ID> --gateway <GATEWAY> \
--name hnas_subnet <NETWORK_ID> <SUBNET_CIDR>Optional - List available subnets:
$ neutron subnet-listAdd the subnet interface to a router, providing the router ID and subnet ID created before:
$ neutron router-interface-add <ROUTER_ID> <SUBNET_ID>Create a file system on HNAS. See the Hitachi HNAS reference.
Make sure that the filesystem is not created as a replication target. Refer official HNAS administration guide.
Prepare the HNAS EVS network.
Create a route in HNAS to the tenant network:
$ console-context --evs <EVS_ID_IN_USE> route-net-add --gateway <FLAT_NETWORK_GATEWAY> \
<TENANT_PRIVATE_NETWORK>Make sure multi-tenancy is enabled and routes are configured per EVS.
$ console-context --evs 3 route-net-add --gateway 192.168.1.1 \
10.0.0.0/24Create a share
Create a default share type before running manila-share service:
$ manila type-create default_share_hitachi False
