DRBD Manage is about automating deployment of DRBD volume instances. It is the glue to higher level management frameworks, such as cloud-manangement systems, enterprise virtualisation solutions or storage target software.
As it has to address a broad range of software layers above it, DRBD Manage needs to be very flexible. In some instances it needs to manage allocation of logic volumes from a pool of nodes having enough free space, other systems may want to do the placement themselves.
DRBD Manage covers creating, removal and snapshotting of volumes. Sole volumes or whole consistency groups. It is a pure control plane component. It requires a DRBD kernel driver version 9.0 or higher.
