Setting Up Network RAID1 With DRBD On Ubuntu 11.10
This tutorial shows how to set up network RAID1 with the help of DRBD on two Ubuntu 11.10 systems. DRBD stands for Distributed Replicated Block Device and allows you to mirror block devices over a network. This is useful for high-availability setups (like a HA NFS server) because if one node fails, all data is still available from the other node. Read more: |

Setting Up An Active/Active Samba CTDB Cluster Using GFS & DRBD (CentOS 5.5)
This article explains how to set up an Active/Active Samba CTDB
Cluster, using GFS and DRBD.
Prepared by Rafael Marangoni, from BRLink Servidor
Linux Team. We use two nodes, both are active nodes, and the requests are
loadbalanced. To replicate data between the nodes we use
DRBD. To active/active cluster, we must use a ClusterFS (in this case
GFS), to make the two nodes to write on the DRBD resource at same time. Read more: |

Installation And Setup Guide For DRBD, OpenAIS, Pacemaker + Xen On OpenSUSE 11.1
The following will install and configure DRBD, OpenAIS, Pacemaker and Xen
on OpenSUSE 11.1 to provide highly-available virtual machines. This setup does
not utilize Xen's live migration capabilities. Instead, VMs will be started
on the secondary node as soon as failure of the primary is detected. Xen
virtual disk images are replicated between nodes using DRBD and all services
on the cluster will be managed by OpenAIS and Pacemaker. The following setup
utilizes DRBD 8.3.2 and Pacemaker 1.0.4. It is important to note that DRBD
8.3.2 has come a long way since previous versions in terms of compatibility
with Pacemaker. In particular, a new DRBD OCF resource agent script and new
DRBD-level resource fencing features. This configuration will not work
with older releases of DRBD. Read more: |
