Download: EVMS (Enterprise Volume Management System) User Guide.

Taken from Preface: This guide tells how to configure and manage Enterprise Volume Management System (EVMS). EVMS is a storage management program that provides a single framework for managing and administering your system’s storage.

This guide is intended for Linux system administrators and users who are responsible for setting up and maintaining EVMS.

For additional information about EVMS or to ask questions specific to your distribution, refer to the EVMS mailing lists. You can view the list archives or subscribe to the lists from the EVMS Project web site.

EVMS lets you manage storage space in a way that is more intuitive and flexible than many other Linux volume management systems. Practical tasks, such as migrating disks or adding new disks to your Linux system, become more manageable with EVMS because EVMS can recognize and read from different volume types and file systems. EVMS provides additional safety controls by not allowing commands that are unsafe. These controls help maintain the integrity of the data stored on the system.

EVMS also provides the capability to manage data on storage that is physically shared by nodes in a cluster. This shared storage allows data to be highly available from different nodes in the cluster.
