Just as for OpenStack, it is possible to deploy the CloudStack management server in a multi-node installation.

HowTo: Offline Upgrade of Galera Cluster to MySQL 5.6 or MariaDB 10
+0 Vote Up -0Vote Down

MySQL 5.6 has an extensive list of new features and changes, so upgrading from a previous version can be risky if not tested extensively. For this reason, we recommend our users to read and understand the changes before doing the upgrade. If you are on older MySQL versions, it is probably time to think about upgrading. MySQL 5.6 was released in February 2013, that’s almost two years ago!

A major upgrade, e.g., from MySQL 5.5 to 5.6 or MariaDB 5.5 to 10, requires the former MySQL/MariaDB server related packages to be …

Diagnosing SST errors with Percona XtraDB Cluster for MySQL
+0 Vote Up -0Vote Down

State Snapshot Transfer (SST) is used in Percona XtraDB Cluster (PXC) when a new node joins the cluster or to resync a failed node if Incremental State Transfer (IST) is no longer available. SST is triggered automatically but there is no magic: If it is not configured properly, it will not work and new nodes will never be able to join the cluster. Let’s have a look at a few classic issues.

Port for SST is not open

The donor and the joiner communicate on port 4444, and if the port is closed on …

New Webinar: A DevOps Guide to Database Infrastructure Automation for eCommerce
+0 Vote Up -0Vote Down

For an online shop, the website is the cash register. It has to be open for business 24 hours a day.

As the ops person on duty, when you get a call at 3am after your website went down, your priority number one is to restore the service asap. But why can we not have our application stack automatically recover, and not have the pager wake us at all? Why do we still stick to tedious manual processes, which take up time and resources, and hinder future growth?

Infrastructure automation isn’t easy, but it’s not rocket science either, says Riaan Nolan. Riaan has been in operations for the past decade, and has …
