Galera Error Failed to Report Last Committed (Interrupted System Call)
+0 Vote Up -0Vote Down

In this blog, we’ll discuss the ramifications of the Galera Error Failed to Report Last Committed (Interrupted System Call).

I have recently seen this error with Percona XtraDB Cluster (or Galera):

[Warning] WSREP: Failed to report last committed 549684236, -4 (Interrupted system call)

It was posted in launchpad as a bug in 2013: https://bugs.launchpad.net/percona-xtradb-cluster/+bug/1434646

My colleague Przemek replied, and explained it as:

MySQL High Availability: The Road Ahead for Percona and XtraDB Cluster
+1 Vote Up -0Vote Down

This blog post discusses what is going on in the MySQL high availability market, and what Percona’s plans are for helping customers with high availability solutions.

One thing I like to tell people is that you shouldn’t view Percona as a “software” company, but as a “solution” company. Our goal has always been to provide the best solution that meets each customer’s situation, rather than push our own software, regardless of whether it is the best …

Building MariaDB 10.1.x and Galera from Source for Multiple Node Cluster Testing Setup
+0 Vote Up -0Vote Down

My Facebook followers probably noted that I quit from Percona some time ago and work for MariaDB since March 1, 2016. I changed the company, but neither the job role (I am still a Support Engineer), nor the approach to do my job. I still prefer to test everything I suggest to customers and I usually use software I …

Galera Cluster and Docker Swarm
+0 Vote Up -0Vote Down

This blogpost extends last one. In the last blogpost, we had a look into Docker Network and how it makes the communication between the containers (over multiple hosts) easier. Of course we used Galera for that :)

In this blogpost we are going to use Docker Swarm to bootstrap a Galera Cluster.

Why using Docker Swarm?

Docker Swarm is (simplified) a proxy. So we've got one accesspoint to manage multiple hosts. (The swarm manage service will run on 172.17.152.11:2376). We also use Docker Swarm to abstract from the nodes. …

Galera meets Docker Network \o/

Galera und Docker Network

Using Docker to run Galera on multiple nodes is quite a mess as described here. It is possible but no fun at all. As Docker does NATing every bidirectional setup is complicated.

Starting with Docker Network (version 1.9) you can simply span a Docker owned network (multiple of them) over multiple nodes. These networks are separated as the known bridged network Docker uses by default. It also provides a simple node/container discovery using the --name switch. Feels like a simple DNS.

Let's have a …

Ahoi, I made three proposals for Percona Live. (Even I know being a lonely (sniff) freelancer with no backup). At least I'm for sure an early adopter about the three topics I submitted and know for sure what I'm talking about *g*   

Even being Puppet certified. Ansible is my love. Never been that fast in doing automation \o/

MariaDB 10.1 is stable GA
+0 Vote Up -0Vote Down

With the release of 10.1.8, MariaDB takes a next step. MariaDB 10.1 is now considered a stable release.

MariaDB 10.1 has a couple of main themes:

  • Security
  • High Availability
  • Scalability

During the last few years there have been many request for more security features in MariaDB. Actually it’s a trend in general. Since open source software is getting more attractive all the time, more functionality is wanted in areas where proprietary software typically has been leading. This is especially true for databases. In addition data privacy is a very hot topic.

The big new thing in security for MariaDB 10.1 …
