Enterprise Volume Management System

The Enterprise Volume Management System (EVMS) Project has the goal of providing unparalleled flexibility and extensibility in managing storage. It represents a new approach to logical volume management, as the architecture introduces a plug-in model that allows for easy expansion or customization of various levels of volume management.

        Release Notes: The Core Engine loads the Device-Mapper kernel module if not present. Minor fixes were made in the cluster-segment-manager. A new command was added to mount volumes. The Disk Manager accepts "*" and "?" wild cards and bracket notation ("[...]") when specifying block devices in evms.conf. The 2.4 and 2.5 kernel versions have been combined into a single plugin. The LVM component has a new "Move-PV" interface. Bugs were fixed with migrating some setups from LVM1 directly to EVMS 2.0 and activation of certain striped LVM regions. RAID-5 was fixed on BBR segments, and there is support for loading the BBR kernel component as a module.
