Comments on Installation And Setup Guide For DRBD, OpenAIS, Pacemaker + Xen On OpenSUSE 11.1
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.

Linbit is an AUSTRIAN company... but probably Austrians are the only ones who care about the difference ;-)
Instead of wget'ting a lot of rpms, you can simply install them via zypper, they are in the standard oss repository that should be available and enabled after installation for everybody: zypper in heartbeat heartbeat-resources openais pacemaker.
OpenIPMI, heartbeat-common and some other packages are drawn as dependency by zypper.
The mentioned repository download.opensuse.org/repositories/openSUSE:/11.1/standard does not exist any more. The version of heartbeat and colleagues ;-) in the server:/ha-clustering repository are newer than those you give, it's 3.x now (2009-09-17). The 2.99 releases are in the standard oss repository.
However, downloading and installing DRBD must still be done as you described, the openSUSE build service provides version 8.2.7 only :-(
But nevertheless: this HowTo is a wonderful starting point for me - I will have to provide Xen servers for our company's SAP systems next year... :-)
Hi, thanks for the tutorial.
I am trying to implement this. It is necessary to have crossover cable?
I have doubt about the IPs of DRDB and Corosync/openais. Where I use the network IP and the crossover board IP?
Thanks in advance,
Felipe
