DRBD bootstrap salt formula

Formulas for setup and managing a drbd cluster using drbdadm.

Mainly adapted to SUSE / openSUSE Linux distributions, but should be usable on other distributions with minor modifications.

GOAL

Enable the configuration and installation of drbd cluster using salt.

How to use

  1. Copy the salt-shaptools modules and states in our salt master. The latest DRBD module/state will be merged into upstream after neon release.
git clone https://github.com/SUSE/salt-shaptools.git
# Create /srv/salt/_modules and /srv/salt/_states if they don't exist
sudo cp salt-shaptools/salt/modules/* /srv/salt/_modules
sudo cp salt-shaptools/salt/states/* /srv/salt/_states
  1. Work with HABOOTSTRAP formula or NFS formula, could deploy NFS on top of DRBD with/without Pacemaker

    NFS formula is packaged in openSUSE build service

Install (Suse distros)

The easiest way to install the formula in SUSE distributions is using a rpm package. For that follow the next sequence to install all the dependencies (opensuse leap 15 is used in the example):

sudo zypper addrepo https://download.opensuse.org/tumbleweed/repo/oss/
sudo zypper ref
sudo zypper in drbd-formula

Note
In some cases it might be needed to adjust the salt minion configuration to use the new style of calling module.run. See this for more information.
