DRBD and Pacemaker: Open source disaster
recovery and high availability clustering
DRBD stands for Distributed Replicated Block Device and allows block
devices to be replicated over a network in a RAID-1 fashion. Since Linux
Kernel 2.6.33, DRBD has been accepted into mainline and with its ever
growing user base defines itself as the de facto Linux data replication
solution. DRBD acts as a block device and can be transparently inserted
underneath virtually any Linux application. Alone, DRBD's replication can
be leveraged as a robust disaster recovery solution ensuring data is kept
geographically diverse between nodes, data centers or continents. Coupled
with other Linux clustering technologies (Pacemaker, Heartbeat, RHCS,
etc.), DRBD's shared-disk semantics become the foundation of a free,
open-source high availability (HA) clustering stack used to provide
complete hardware and service level fault tolerance. From databases to
virtualization to centralized storage, DRBD and Pacemaker provide a
completely free, open-source availability and redundancy solution using
commodity, off-the-shelf hardware.
This talk will first provide an introduction to DRBD: what it does, how it
works, and some live demonstrations of replication-in-action. Basic HA
concepts will be covered as well as an overview of Pacemaker and the Linux
HA cluster stack as it relates to DRBD. To give a sense of its
flexibility, common and interesting use cases will be presented ranging
from simple, locally deployed HA clusters to geographically dispersed,
cross-site disaster recovery installations. Finally, attendees will see
how the current Open Cluster Framework (OCF) standards provide users with a
generic and easy way of integrating their own custom applications into a
highly-available environment using freely available open-source software.
Attendees are expected to have some system administration experience
related to storage and networking. Knowledge of the Linux kernel and other
shared storage technologies is helpful, but not necessary.

About the speaker:
Adam is an expert in open-source clustering and high availability.
Originally from New England, Adam lives in Portland, OR where he has been
working at LINBIT, developers of DRBD and maintainers of Heartbeat. Aside
from providing top-level Linux High-Availability and Disaster Recovery
consulting for customers in the Americas, he also leads LINBIT training
courses in the US, doubles as a technical writer and regularly contributes
to related open-source projects. Adam enjoys his R cloud, virtualization,
HPC and distributed computing environments.
Meeting Location:
Please note that this meeting will be held at IBM, 590 Madison Ave,
12th floor, corner of 57th Street, and not at Google. This is

Swag (Give Away):
During/after the meeting... unusually terrific swag may be given
away.
Stammtisch:
After the meeting ... You may wish to join up with other NYLUGgers
for drinks and pub food. This month we'll be over at TGI Friday's
(677 Lexington and 56th Street, Second floor, Northeast corner),
but we are also evaluating other options for the future and welcome
your suggestions.

Coding Workshops/Hacking Society:
This is a group of people that wants to learn about and work on coding
in Python, Smalltalk, C++, and other languages, and hack on code.
Sometimes they go out to eat afterward.
Bring something to show off and discuss!
The workshops meet every other Tuesday, at the NY Public Library,
Hudson Park Branch. 66 Leroy St. NY NY from 6:00 PM - 8:00 PM
Next meetings are August 17, and August 31.
