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.

[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
