OpenStack Victoria : How to use Manila (Local Device)
2021/09/02
 
This is How to use OpenStack Shared File System (Manila).
This example is based on the environment like follows.
For example, Configure a local block device as a shared storage on Storage Node and use it on Instances.
Therefore, it needs there is a free block device on Storage Node.

[1] Configure Storage Node.
root@storage:~#
apt -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_ips = 10.0.0.50
root@storage:~#
systemctl restart manila-share nfs-server

root@storage:~#
systemctl enable manila-share nfs-server
[2] Create a 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
