|
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.

| [1] | Configure Storage Node. |
|
[root@storage ~]#
dnf -y install nfs-utils nfs4-acl-tools # create a volume for Manila on free block device [root@storage ~]# pvcreate /dev/sdc1 Physical volume "/dev/sdc1" successfully created [root@storage ~]# vgcreate manila-volumes /dev/sdc1 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 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) |
