DRBD

Distributed Replicated Block Device (DRBD) is a distributed replicated storage system for the <a href="/facts/Linux/9FvCKSTq">Linux</a> platform. It mirrors <a href="/facts/Block_devices/t8ISnXft">block devices</a> between multiple hosts, functioning transparently to applications on the host systems. This replication can involve any type of block device, such as hard drives, partitions, RAID setups, or logical volumes.
DRBD is implemented as a kernel driver, several <a href="/facts/Userspace/0yIzMY8t">userspace</a> management applications, and some <a href="/facts/Shell_scripts/NE7YvsBD">shell scripts</a>. DRBD is traditionally used in <a href="/facts/High_availability/y3J8GnEo">high availability</a> (HA) <a href="/facts/Computer_cluster/mT7S1BcX">computer clusters</a>, but beginning with DRBD version 9, it can also be used to create larger software defined storage pools with a focus on cloud integration.
The DRBD software is <a href="/facts/Free_software/IaoVtJXn">free software</a> released under the terms of the <a href="/facts/GNU_General_Public_License/S75KhLSX">GNU General Public License</a> version 2.
DRBD is part of the <a href="/facts/Lisog/jILcK3aE">Lisog</a> open source stack initiative.
