vg

Vagrant based deployment of Gluster and Glusto, via Ansible

What is it

Simplify the deployment of Gluster + Glusto, its testing suite and framework, to enable easier testing of Gluster in an isolated (VM) environment. The deployment uses Gluster-Ansible to deploy Gluster in a standard manner.

Requirements

Linux OS (developed and tested on Fedora 29/30)
Git to clone the repo
Vagrant, libvirt (+KVM), libvirt-provider for vagrant, Ansible.

Basic usage

Clone the repo to your computer.
Assuming you have the basic requirements on the host (Ansible, libvirt, Vagrant, libvirt-provider for vagrant) then vagrant up should bring the environment up in ~4-5m (might take longer in the initial run, as it downloads the CentOS box).
To run tests, SSH to node-0 via vgrant ssh node-0 , then switch to root su - (password is 'foobar'). You can now cd /root/glusto-tests and run the tests, as you would normally with Glusto. For example: glusto -c /root/gluster_tests_config.yml --pytest='-v -x tests/functional/bvt/test_cvt.py --junitxml=/tmp/cvt-junit.xml'

vg's Issues

The machine config needs to be updated to install the build from the correct branch

The machine_config.yml needs to install the gluster build from devel branch instead of master branch.

$ grep  "http://artifacts.ci.centos.org/gluster/nightly/" ./ansible/machine_config.yml
        baseurl: "http://artifacts.ci.centos.org/gluster/nightly/master/$releasever/$basearch"

Unable to start the glusterd while trying the upgrade test

While trying to write an upgrade test, I was unable to start the glusterd

[root@node-1 ~]# systemctl status glusterd

I was seeing the following error in the glusterd logs :

But Once I installed glusterfs-geo-replication and then tried to restart it did not give any problem.
