Abstract: A volume management server may regularly check the status of persistent volumes to determine if they have been released. A database with information about the persistent volumes may be updated to indicate a current date as the release date when a persistent volume is found to be released without a release date. This enables the volume management server to determine, in the future, how long the persistent volume has been released. When the difference between the current date and the release date for a persistent volume reaches a first predetermined age threshold, the volume management server notifies a set of users. When the difference between the current date and the release date for the persistent volume reaches a second predetermined age threshold, the volume management server causes deletion of the persistent volume.

The magnitude for the read reference voltage depends on a programmed status of the word lines in the one or more unselected sub-blocks in the selected block when the read reference voltage is applied to the selected word line.
