Removing Cluster Permissions Using the CLI or REST API

The acl set command specifies the entire ACL for a cluster or volume. Any previous permissions are overwritten by the new values, and any permissions omitted are removed. To remove cluster permissions, run the acl set command and omit the permissions to remove. See acl set for complete reference information.
