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@network:~#
apt -y install lvm2 nfs-kernel-server # 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 restart manila-share nfs-server root@network:~# 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) |
