OpenStack Ocata : How to use Manila
2017/03/18 |
|
This is How to use OpenStack Shared File System (Manila).
This example is based on the emvironment 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.

| [1] | Configure Storage Node. |
|
root@storage:~#
apt-get -y install lvm2 nfs-kernel-server # create a volume for Manila on free block device root@storage:~# pvcreate /dev/sdb1 Physical volume "/dev/sdb1" successfully created root@storage:~# vgcreate manila-volumes /dev/sdb1 Volume group "manila-volumes" successfully created
root@storage:~#
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_ip = 10.0.0.50 systemctl restart manila-share nfs-server root@storage:~# systemctl enable manila-share nfs-server

| [2] | Create default share type. It's OK to work on any node. (This example is on Control Node) |
|
root@dlp ~(keystone)# manila type-create default_share_type False +----------------------+--------------------------------------+ | Property | Value | +----------------------+--------------------------------------+ | required_extra_specs | driver_handles_share_servers : False | | Name | default_share_type | | Visibility | public | | is_default | - | | ID | 98accd2e-b951-448b-9467-10a6e9aaa374 | | optional_extra_specs | | +----------------------+--------------------------------------+root@dlp ~(keystone)# manila type-list +-----------+--------------------+------------+------------+--------------------------------------+----------------------+ | ID | Name | visibility | is_default | required_extra_specs | optional_extra_specs | +-----------+--------------------+------------+------------+--------------------------------------+----------------------+ | 98accd2e- | default_share_type | public | YES | driver_handles_share_servers : False | | +-----------+--------------------+------------+------------+--------------------------------------+----------------------+ |
| [3] | Create NFS share. |
|
root@dlp ~(keystone)# manila create NFS 10 --name share01

| [4] | It's OK all, you can use Manila Shared filesystem from Instances like follows. |
