The average write speed was about 1 MB/s which is unacceptable for a filesystem that will undergo a lot of writes. I decided that it was time to take action and started looking at kernel parameters that could be changed.

Running a Gluster Cluster on the Raspberry Pi with Docker

I was always fascinated with distributed filesystems and wanted to learn more about Gluster since it is becoming more popular in larger open-source projects. Since I have a few Raspberry Pi’s, I thought that now is the best time to learn. This blog post will explain how to run Gluster on a two-node Raspberry Pi cluster from a Docker container.

Architecture

  1. Two Raspberry Pi’s (rpi-1 and rpi-2)
  2. Running a Gluster image from a local Docker registry
  3. Hostnames are resolvable in /etc/hosts on both Pi’s
  4. Docker 1.12.x installed
