This paper discusses the steps necessary to build a highly available LogZilla cluster environment. The team of Logzilla outlines all the necessary tools to build the cluster from scratch using Ubuntu 12.04 LTS servers. It is assumed that the reader has a firm grasp on the use of Ubuntu Linux and Linux commands in general. - Note: This guide is not written by LINBIT, the credit belongs to the LogZilla team

TECH GUIDES

In non-cloud based Linux HA clusters, virtual IP failover is the typical method for redirecting clients to the active node. In the cloud, this method generally requires a virtual IP resource agent capable of orchestrating the IP failover with the cloud platform.

TECH GUIDES

GitLab is a complete DevOps platform used by many organizations and developers. GitLab can be easily installed as a self-managed web application. This guide will demonstrate installing and configuring a highly available (HA) two node GitLab CE (Community Edition) environment using Pacemaker and DRBD.

TECH GUIDES

The following reference architecture is specific to deploying HA Jenkins pods onto LINSTOR backed persistent storage in EKS stretching across multiple AZs, but could be adapted for other workloads that need cross AZ replication without sacrificing performance.

Storage

TECH GUIDES

This guide outlines the configuration of a highly-available iSCSI storage cluster using DRBD, Pacemaker, and Corosync. iSCSI provides access to block devices via TCP/IP, which allows storage to be accessed remotely using standard networks.

TECH GUIDES

This guide can be used to deploy a High Availability (HA) NFS cluster using DRBD, Pacemaker, and Corosync on a RHEL/CentOS 8 server. After following the instructions outlined in this guide, transferring data to or from an NFS export, to or from a client system, should not be interrupted during failover.

TECH GUIDES

This guide describes an approach for designing and implementing High Availability (HA) MySQL cluster using DRBD, Pacemaker, and Corosync on RHEL 8 or CentOS 8 servers.

TECH GUIDES

The solution will require three EC2 instances to be provisioned and set up. Two of these EC2 instances will serve as nodes to the Oracle database high-availability solution, and the DRBD cluster, while the third one will be used to offer disk quorum to the DRBD cluster but won’t play any other role in the solution.

Virtualization

TECH GUIDES

You run OpenVZ container based virtualization? Then you’ll need this document to make your containers highly available. With this step-by-step guide, we’ll show you how to use NFS to quickly and easily migrate containers between physical servers — and how to use that functionality for high availability!

Performance

TECH GUIDES

Infiniband with DRBD. In this paper, we discuss High Speed, Low Latency replication (IPoIB or SDP protocols) with LINBIT’s DRBD in combination with Infiniband interconnect technology.

TECH GUIDES

In this guide we test out two Intel DC S 3700 Series 800GB SATA SSD drives to evaluate them regarding replication speed and also to determine the performance overhead when used in a synchronous replication setup.

TECH GUIDES

In this tech-guide LINBIT evaluates two SanDisk Optimus AscendTM 2.5 “800 GB SAS solid state disks regarding performance and synchronous replication overhead.

Disaster Recovery

TECH GUIDES

This tech-guide describes a setup consisting of two highly available Pacemaker clusters in two sites, with a routed IPv4 or IPv6 connection in between that can range from a few Mbit/sec up to 10GBit/ sec, depending on the IO load imposed on the cluster nodes.

TECH GUIDES

In this guide we will show how to utilize Amazons EC2 and LINBITs DRBD/DRBD Proxy combo to replicate data to the cloud for off-site replication. Common uses of this type of implementation are Disaster Recovery and Disaster Avoidance.

TECH GUIDES

Geo Clustering with Oracle DynDNS failover – IN A WORLD where disaster can strike at any time, availability of services and data is a must. Utilizing LINBIT’s DRBD, DRBD Proxy, and several other open source components, we can ensure that even in the event of an entire data center going offline, services and data are available.

TECH GUIDES

This guide covers two common DRBD Proxy implementations. The first method uses DRBD proxy in a newly configured two-node DRBD cluster to replicate data to a peer over a high latency WAN connection; this method is common for customers looking for a disaster recovery solution.

Miscellaneous
