Using DRBD to Build High-Availability Clusters on Commodity Hardware

Charlie Schluting of LINBIT will explain how DRBD works and how people
currently use it, with enough information to get you started building
your own clusters.

DRBD stands for Distributed Replicated Block Device, and as the name
implies, allows you to replicate block devices over TCP. DRBD is
extremely flexible due to the fact it is a block device, and as such is
used in a variety of situations. At the most basic level, you can
replicate data between two servers to provide synchronously replicated
storage redundancy for either failover or disaster recovery purposes. In
active/active mode, you can also run GFS, OCFS2, or other clustered file
systems.

Topics that will be covered:
- How it works, history, and future exciting news regarding mainline
kernel inclusion
- How it is used: HA-iSCSI, HA-NFS, Virtualization, Apache, Samba, etc.
- Cluster Resource Manager options and recommendations, and news about
the confusing changes in the Linux-HA / Clusterlabs communities.

And the majority of the time will be spent on:
- Example cluster configuration: hardware setup, installation and
configuration, and cluster manager integration.

Come with questions!
