The Top Issues and Topics for HA-DR in 2018

2017 is coming to a close and it is a good time to look back and then look forward. Thank you to our customers, partners, and the broader open source community for your participation, 2017 was a year of many accomplishments for LINBIT. We celebrated over 1.6 million downloads of DRBD, expanded into China, and released 4 new technical guides: HA NFS on RHEL 7, HA iSCSI on RHEL 7, HA & DR for ActiveMQ, and DRBD with Encryption.

Deploy a DRBD/Pacemaker Cluster using Ansible

We get asked the question, “do you have a sandbox cluster we can play around in?”, by admins and potential clients looking to get a feel for managing a DRBD/Pacemaker cluster fairly often. Instead of spinning up some cloud instances and doling out access, we decided it would be better for our potential clients to be able to see how it all works in their actual environment. Ansible seemed like the best way to create a “one size fits all” solution for deploying such clusters into an unknown environment, and after a few days hacking together a playbook, it proved to be a good choice.

The end result was an Ansible playbook that can deploy a few different cluster configurations onto a pair of nodes in any environment. The playbook prompts the user for some inputs that will specify which type of cluster to deploy, which LINBIT contract to register the target nodes with, and which credentials to use for said registration; all of which could be set in your inventory file or passed via extra arguments on the command line to avoid prompting. After the playbook runs, you’re left with an initialized DRBD device and Pacemaker cluster at the very least, or a full blown HA cluster serving out either iSCSI or NFS (expect more later) that you can test with until your heart’s content.

You can find directions and my Ansible playbook’s repo on GitHub.

LINBIT Delivers High Availability and Disaster Recovery for Apache ActiveMQ Messaging Software

LINBIT Solution Simplifies HA and DR for ActiveMQ

BEAVERTON, Ore., Dec. 6, 2017 — LINBIT, a leader in open source High Availability (HA), Software Defined Storage (SDS), Disaster Recovery (DR) and the force behind the DRBD software, today announced that it is bringing disaster recovery capabilities to Apache ActiveMQ™, the most popular open source messaging and Enterprise Integration Pattern (EIP) server software.  

The LINBIT solution simplifies HA and DR for ActiveMQ because it does not require a clustered file system or shared database, a common requirement in current HA/DR implementations.

“Reliable communication in a distributed environment is a critical part of modern IT systems,” said Philipp Reisner, CEO of LINBIT. “LINBIT DR for ActiveMQ reduces cost and complexity for data centers and mitigates the risk often seen with SAN, clustered file systems, or shared databases.”

At TruckPro, the LINBIT DRBD software “is used primarily for resiliency,” stated Henry Santamaria, Director of Infrastructure. “Uptime is important for our business and anything we can do to quickly recover from any issue is paramount. Our investment in LINBIT yielded a noticeable increase in performance and stability which we did not have before.”

Known for its stability and performance over the last 15 years, LINBIT software is used by thousands of organizations across the globe, and is embedded in products from independent software vendors and established equipment manufacturers under OEM agreements. “With over 10,000 downloads per month, it is easy to see why even the most demanding environments rely on LINBIT to reduce risk and improve performance,” said Brian Hellman, LINBIT COO.
