Creating a backup of a Cinder volume on an NFS share fails with a memory error.
Problem
Attempting to create backup of a Cinder volume results in an out of memory error.
Cause
There is lack of available memory on the controller.
Solution
- Implement the custom.yml file.
sudo mkdir -p /opt/vmware/vio/custom sudo cp /var/lib/vio/ansible/custom/custom.yml.sample /opt/vmware/vio/custom/custom.yml
- Edit the /opt/vmware/vio/custom/custom.yml file.
Depending on the available controller memory, reduce the value of the cinder_backup_file_size parameter.
- Save the custom.yml file.
- Push the new configuration to your VMware Integrated OpenStack deployment.
viocli deployment --verbose configure --limit controller
