OpenStack Yoga : How to use Manila (Local Device)2022/06/10 |
This is How to use OpenStack Shared File System (Manila).
This example is based on the environment like follows.
For example, Configure local block device as shared storage on Storage Node and use it from Instances.
Therefore, it needs there is a free block device on Storage Node. ------------+-----------------------------+-----------------------------+------------ | | | eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51 +-----------+-----------+ +-----------+-----------+ +-----------+-----------+ | [ dlp.srv.world ] | | [ network.srv.world ] | | [ node01.srv.world ] | | (Control Node) | | (Storage Node) | | (Compute Node) | | | | | | | | MariaDB RabbitMQ | | Open vSwitch | | Libvirt | | Memcached httpd | | Neutron Server | | Nova Compute | | Keystone Glance | | OVN-Northd | | Open vSwitch | | Nova API Cinder API | | Cinder Volume | | OVN Metadata Agent | | Manila API | | Manila Share | | OVN-Controller | +-----------------------+ +-----------------------+ +-----------------------+ |
[1] | Configure Storage Node. |
[root@network ~]#
dnf -y install nfs-utils nfs4-acl-tools # create a volume for Manila on free block device [root@network ~]# pvcreate /dev/sdc1 Physical volume "/dev/sdc1" successfully created [root@network ~]# vgcreate manila-volumes /dev/sdc1 Volume group "manila-volumes" successfully created
[root@network ~]#
vi /etc/manila/manila.conf # add follows into [DEFAULT] section
enabled_share_backends = lvm
# add to the end [lvm] share_backend_name = LVM share_driver = manila.share.drivers.lvm.LVMShareDriver driver_handles_share_servers = False lvm_share_volume_group = manila-volumes lvm_share_export_ips = $my_ip systemctl enable --now openstack-manila-share nfs-server

[2] | Create default share type. It's OK to work on any node. (example below is on Control Node) |
[root@dlp ~(keystone)]# manila type-create default_share_type False +----------------------+--------------------------------------+ | Property | Value | +----------------------+--------------------------------------+ | ID | b01f8275-6926-44c1-a2d9-c4e3699b10ac | | Name | default_share_type | | Visibility | public | | is_default | YES | | required_extra_specs | driver_handles_share_servers : False | | optional_extra_specs | | | Description | None | +----------------------+--------------------------------------+[root@dlp ~(keystone)]# manila type-list +--------------------------------------+--------------------+------------+------------+--------------------------------------+----------------------+-------------+ | ID | Name | visibility | is_default | required_extra_specs | optional_extra_specs | Description | +--------------------------------------+--------------------+------------+------------+--------------------------------------+----------------------+-------------+ | b01f8275-6926-44c1-a2d9-c4e3699b10ac | default_share_type | public | YES | driver_handles_share_servers : False | | None | +--------------------------------------+--------------------+------------+------------+--------------------------------------+----------------------+-------------+ |
[3] | Login as a common user to create Manila NFS Share. |
[cent@dlp ~(keystone)]$ manila create NFS 10 --name share01 --share-type default_share_type +---------------------------------------+--------------------------------------+ | Property | Value | +---------------------------------------+--------------------------------------+ | id | 61e2ecfd-f395-419b-a21c-5533b38ebae1 | | size | 10 | | availability_zone | None | | created_at | 2022-06-10T06:37:20.796486 | | status | creating | | name | share01 | | description | None | | project_id | 911e5ff7686741c782d6acc6d7155db1 | | snapshot_id | None | | share_network_id | None | | share_proto | NFS | | metadata | {} | | share_type | b01f8275-6926-44c1-a2d9-c4e3699b10ac | | is_public | False | | snapshot_support | False | | task_state | None | | share_type_name | default_share_type | | access_rules_status | active | | replication_type | None | | has_replicas | False | | user_id | 1ff4591a7f8140fcad38fd9f606a66a6 | | create_share_from_snapshot_support | False | | revert_to_snapshot_support | False | | share_group_id | None | | source_share_group_snapshot_member_id | None | | mount_snapshot_support | False | | progress | None | | is_soft_deleted | False | | scheduled_to_be_deleted_at | None | +---------------------------------------+--------------------------------------+ # OK if the Status turns to [available] after a few minutes [cent@dlp ~(keystone)]$ manila list +--------------------------------------+---------+------+-------------+-----------+-----------+--------------------+------+-------------------+ | ID | Name | Size | Share Proto | Status | Is Public | Share Type Name | Host | Availability Zone | +--------------------------------------+---------+------+-------------+-----------+-----------+--------------------+------+-------------------+ | 61e2ecfd-f395-419b-a21c-5533b38ebae1 | share01 | 10 | NFS | available | False | default_share_type | | nova | +--------------------------------------+---------+------+-------------+-----------+-----------+--------------------+------+-------------------+ |
[4] | That's OK, you can use Manila Shared filesystem on your own instances like follows. |
