How to add an existing Percona XtraDB Cluster to Percona ClusterControl
+0 Vote Up -0Vote Down

In my last blog post I explained how to use Percona ClusterControl to create a new Percona XtraDB Cluster from scratch. That’s a good option when you want to create a testing environment in just some mouse clicks. In this case I’m going to show you how to add your existing cluster to Percona ClusterControl so you can manage and monitor it on the web interface.

The environment will be pretty similar, we will have UI, CMON and 3 XtraDB Cluster nodes. The cluster should be already running and Percona ClusterControl also installed.

Innodb redo log archiving
+1 Vote Up -0Vote Down

Percona Server 5.6.11-60.3 introduces a new “log archiving” feature. Percona XtraBackup 2.1.5 supports “apply archived logs.” What does it mean and how it can be used?

Percona products propose three kinds of incremental backups. The first is full scan of data files and comparison the data with backup data to find some delta. This approach provides a history of changes and saves disk space by storing only data deltas. But the disadvantage is a full-data file scan that adds load to the disk subsystem. The second kind of incremental

Changing an async slave of a PXC cluster to a new Master using 5.6 and GTID
+1 Vote Up -0Vote Down

Before Percona XtraBackup 2.1.7 and Percona XtraDB Cluster 5.6.15-25.3, rsync was the only SST method supporting GTID in the way that it was possible to move an asynchronous slave from one Galera node to another one (related bug).

Indeed, previous versions of Percona XtraBackup didn’t copy any binary log and due to that, moving the async slave to another master, just broke replication (when writes still happened).

Now with the latest version of Percona XtraBackup and Percona XtraDB Cluster, wsrep_sst_xtrabackup-v2 handles the last binlog
