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.</p> <p>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.</p> <p>And the majority of the time will be spent on: - Example cluster configuration: hardware setup, installation and configuration, and cluster manager integration.</p> <p>Come with questions!</p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="http://www.linbit.com/en/">Website</a></li> </ul> </div>
