glusterfs

Ansible Role: GlusterFS

Installs and configures GlusterFS on Linux.

Requirements

For GlusterFS to connect between servers, TCP ports 24007, 24008, and 24009/49152+ (that port, plus an additional incremented port for each additional server in the cluster; the latter if GlusterFS is version 3.4+), and TCP/UDP port 111 must be open. You can open these using whatever firewall you wish (this can easily be configured using the geerlingguy.firewall role).

This role performs basic installation and setup of Gluster, but it does not configure or mount bricks (volumes), since that step is easier to do in a series of plays in your own playbook. Ansible 1.9+ includes the gluster_volume module to ease the management of Gluster volumes.

Role Variables

Available variables are listed below, along with default values (see defaults/main.yml):

glusterfs_default_release: ""

You can specify a default_release for apt on Debian/Ubuntu by overriding this variable. This is helpful if you need a different package or version for the main GlusterFS packages (e.g. GlusterFS 3.5.x instead of 3.2.x with the wheezy-backports default release on Debian Wheezy).

glusterfs_ppa_use: true
glusterfs_ppa_version: "LATEST"

For Ubuntu, specify whether to use the official Gluster PPA, and which version of the PPA to use. See Gluster's Getting Started Guide for more info.

glusterfs_gpg_key_version: "7"
glusterfs_deb_version: "LATEST"

For Debian, specify the version of the GPG key and apt package repository to use. See Gluster's Getting Started Guide for more info.

Dependencies

None.
