If you haven't done so yet, you need to Install and configure OpenStack Pike with Kolla as a standalone.

You also need to add a new 100 GB disk to the Ubuntu 16.04 virtual machine built in the previous article. In this lab, the new 100 GB disk will be /dev/sdb.

$ sudo pvcreate /dev/sdb

2- Create a volume group.

$ sudo vgcreate cinder-volumes /dev/sdb

3- Edit the modules configuration file.

$ sudo vim /etc/modules

# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

5- Rebuild the initramfs.

$ sudo update-initramfs -u

6- Reload the daemon configurations.

$ sudo systemctl daemon-reload

7- Stop and disable open-iscsi.

$ sudo systemctl disable open-iscsi

8- Stop and disable iscsid.

$ sudo systemctl stop iscsid

$ sudo systemctl disable iscsid
