A spread strategy placement group is required to ensure that OneFS nodes are placed on distinct hardware to ensure high availability. It is highly recommended to name your placement group with a format of <cluster_name>-onefs-placement-group by replacing the <cluster_name> with your planned configuration defined in the section Planning cluster configuration details. Write down your placement group name for future reference.
Run the following command by replacing the <aws_region> and <cluster_name> with your settings. It is recommended that you add a tag {Key=cluster-name,Value=<cluster_name>} for future management convenience.
aws ec2 create-placement-group --strategy spread --group-name <cluster_name>-onefs-placement-group --region <aws_region> --tag-specifications “ResourceType=placement-group,Tags=[{Key=cluster-name,Value=<cluster_name>}]”
The following is an example to create the placement group:
> aws ec2 create-placement-group --strategy spread --group-name vonefs-cfv-onefs-placement-group --region us-east-1 --tag-specifications “ResourceType=placement-group,Tags=[{Key=cluster-name,Value=vonefs-cfv}]”
