      How to extend a bootable volume using Openstack CLI

      Introduction

      In this tutorial, we will show you how to increase the size of your (bootable) volume.

      Prerequisites:

      STEP 1: Volume ID

      In order to extend the volume storage, we need to know the volume ID. You can look it up using the following command.

      $ openstack volume list

      STEP 2: Extend (bootable) volume

      Now, let’s extend our volume to 20 GB. Replace the <volume-id> with that of your own.

      note: The volume must be detached from an instance.

      $ openstack volume set <volume-id> --size 20

      STEP 3: Stop and restart

      To let your instance know that you have more disk space available on your volume, you have to shut down the machine and start it again, a restart will not do it.

      $ openstack server stop <server-name>
      $ openstack server start <server-name>

      That's it, to confirm that your operating system sees the new volume size you can log in using SSH and use the list block device command:

      $ lsblk

      Conclusion

      You have now extended the bootable volume of your instance using the OpenStack CLI tools.
