A method and an apparatus for enabling and disabling features in a logical volume management environment is presented. This operation can be performed at boot time or at run time. The user is shown a list of features as well as the current state for each feature. If the feature is currently enabled, the user can select to disable the feature, provided this is a safe operation given the current features for the volume. If the feature is disabled, the user has the following choices: re-enable, disable and retain in the feature stack, disable and remove from the feature stack, and permanently remove the disabled feature from the volume. Disabling or re-enabling features can be very useful to accommodate a changing operating environment. For example, the feature Volume Mirroring allows a replication of the volume at a remote site. If due to network difficulties that remote site becomes inaccessible, then this feature would have to be disabled. At a later time when the site becomes accessible again, the feature can be re-enabled.
