Author: rafatmb • Tags: samba, centos, high-availability, storage • Comments: 2Setting 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.

How To Set Up An Active/Passive PostgreSQL Cluster With Pacemaker, Corosync, And DRBD (CentOS 5.5)
Author: rafatmb • Tags: centos, high-availability • Comments: 8How To Set Up An Active/Passive PostgreSQL Cluster With Pacemaker, Corosync, And DRBD (CentOS 5.5) This article explains how to set up (and monitor) an Active/Passive PostgreSQL Cluster, using Pacemaker with Corosync and DRBD. We use two nodes, one active (that answers requests from apps) and the other on passive mode. If the active server is down, the passive one will automatically take its position (being the active node). We are using the CentOS 5.5 (64bits) distribution, but it will probably work on Fedora (and Red Hat, for sure) as well.
