Using shared folders to implement the quorum disk for a failover clusterIn the previous blog post we've introduced how to build a Distributed File System (DFS), and we've explained how to configure DFS to be highly available, so today's blog post We'll show you how to use DFS to make our Windows cluster arbitration disk.Don't know if you know me in front of the blog post Why do I want to be highly available for DFS configuration, in fact, I configure

Before leader triggers failover, wait a few seconds (then 0~5) for other Sentinel instances to prepare and adjust. If all is well, then leader needs to start upgrading a salve to master, which must be in a good state (not in the Sdown/odown state) and with the lowest weight value (redis.conf), when Master is confirmed, Start failoverA) "+failover-triggered": Leader began

15.7 multi-subnet failover clusters15.7.1 Multi-subnetSQL Server 2012 introduces a stretch cluster set (Stretch Clusters) that enables clustering across geographically dispersed sites. Each failover cluster node is connected to a different subnet (or subnet group) and is therefore referred to as a multi-subnet failover cluster.In a multi-subnet cluster, there is

The impact of messages on SOA In the first part of the message, I wrote about many long-standing best practices from the point-to-point messaging architecture to the service-oriented development requirements update message domain. Here, we will consider a case study to understand the migration, failover, and extension of the queue manager, and the impact on naming conventions, tools, management processes, and operations when considering these activit

MHA IntroductionMHA is a MySQL, a Japanese MySQL Daniel written in Perl failover scheme to ensure the high availability of the database system. During downtime (usually within 10-30 seconds), complete failover, deploy MHA, avoid master-slave consistency issues, and save on the cost of purchasing new servers, Does not affect server performance, easy to install, and does not change existing deployments.also s

Code parsing for MHA failover and online switching Some time ago my colleague Shen Rongshing tidied up the code flow for MHA failover and online switching, and after obtaining their consent, forward it here. The following is the textThis article is based on MySQL5.5, so it does not involve gtid related content. MHA's master-slave switching process is divided into fail
