What is DRBD?

DRBD® (Distributed Replicated Block Device) is an open-source solution focused on block storage replication for Linux, designed to deliver high-performance and high-availability (HA) data services by either synchronously or asynchronously mirroring local block devices between nodes in real-time. As a virtual block-device driver that is intricately woven into the Linux kernel, DRBD ensures optimal local read performance while enabling efficient write-through replication to partner devices. The accompanying user-space tools, such as drbdadm, drbdsetup, and drbdmeta, enhance the management experience through declarative configuration, metadata handling, and comprehensive administration across various installations. Originally created for two-node HA clusters, the latest iteration, DRBD 9.x, has adapted to support multi-node replication and integrate smoothly into software-defined storage (SDS) systems like LINSTOR, broadening its utility in cloud-native environments. This progression underscores the increasing necessity for resilient data management solutions in today's complex technological landscape, highlighting the importance of adaptability in meeting evolving demands.
