How do I configure Block Storage to use an NFS storage back end in OpenStack

Question

Hi everyone,

I know about Cinder service. These service manages block storage. Whenever we need storage, it will use some technology in back end and make partitions and give us storage. But is there any way so that in back end it will use NFS technology?

Thank You

Hi@akhtar,

You can use NFS technology for your storage. Follow the below given steps.

• Log in as root to the system hosting the cinder volume service.

• Create a text file named nfsshares in the /etc/cinder/ directory.

  Add an entry to the /etc/cinder/nfsshares file for each NFS share that the cinder volume service should use for back end storage. Each entry should be a separate line, and should use the following format.

  HOST:SHARE

• Set /etc/cinder/nfsshares to be owned by the root user and the cinder group:

  # chown root:cinder /etc/cinder/nfsshares
  

• Set /etc/cinder/nfsshares to be readable by members of the cinder group:

  # chmod 0640 /etc/cinder/nfsshares
  

• Now configure the cinder volume service to use the /etc/cinder/nfsshares file created earlier. To do so, open the /etc/cinder/cinder.conf configuration file and set the nfs_shares_config configuration key to /etc/cinder/nfsshares.

• Optionally, You can provide any other additional NFS mount options required in your own system environment in the nfs_mount_options configuration key of /etc/cinder/cinder.conf. If your NFS shares do not require any additional mount options (or if you are unsure), skip this step.

• Configure the cinder volume service to use the correct volume driver, namely cinder.volume.drivers.nfs.NfsDriver. To do so, you now open the /etc/cinder/cinder.conf configuration file and set the volume_driver configuration key to cinder.volume.drivers.nfs.NfsDriver.

• You can now restart the service to apply the configuration.

Hope this will work.

Thank You
