0.3.3
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.
Enable the configuration and installation of drbd cluster using salt.
- 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
- 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
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
