Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

This cookbook is designed to setup and configure a pair of server with
Please Note: this cookbook does not mount the drbd drive.

This cookbook assumes that you want it to control your firewall using iptables,
as such it will attempt to open/close the correct ports. If you want to disable
this functionality you can modify the attribute node['iptables']['enabled']
and set it to false.

This cookbook can be used in the following situations:

1) Fresh server pair installation (please see below for how to use).

2) Adding a server to another server running drbd.

3) Change drbd.conf file and have drbd update with out restarting.


How to use when creating a fresh server pair:


  • Chef client must be installed on both servers.

  • The disk location node['drbd']['disk']['location'] must exist.

Note: In order for this work properly both servers need to be running chef
at the same time,

You will need to have the following attribute values specified:

node['drbd']['primary']['fqdn'] and node['drbd']['partner']['hostname']

Note: If you do not specify both attributes then the chef run will error out.

Once one server has been specified as drbd master you can add the recipe
"drbd::drbd_fresh_install" to the run_list of both servers.

How to use when adding a new server to another server running drbd:

This is the same as above except the new server is not specified as the drbd
master, and you dont have to be running chef-client on the other server.

How to use when changing the drbd.conf file:

On which ever server you are updated (or both) add the recipe
"drbd::drbd_inplace_upgrade" to the server's run_list. And the next
time Chef-client runs it will preform the changes in a safe way.

The way I have used this have been to call this drbd cookbook from within
another cookbook, and have the second cookbook do the logic of decided whether
or not this is a fresh install or inplace upgrade.

Here is how I use it:

if ::File.exists?("/etc/drbd.conf")
  include_recipe "extended_drbd::drbd_inplace_upgrade"
  include_recipe "extended_drbd::drbd_fresh_install"


  • default['drbd']['packages'] = ["kmod-drbd83", "drbd83"]
  • default['drbd']['disk']['location'] = "/dev/local/data"
  • default['drbd']['mount'] = "/data"
  • default['drbd']['fs_type'] = "ext3"
  • default['drbd']['dev'] = "/dev/drbd0"
  • default['drbd']['master'] = false
  • default['drbd']['port'] = 7789
  • default['drbd']['configured'] = false
  • default['drbd']['syncrate'] = "36M"
  • default['drbd']['resource'] = "data"
  • default['drbd']['stop_file'] = "/etc/drbd_stop_file"
  • default['drbd']['synced']['stop_file'] = "/etc/drbd_synced_stop_file"
  • default['drbd']['initialized']['stop_file'] = "/etc/drbd_initialized_stop_file"

  • default['drbd']['primary']['fqdn'] = nil - Fqdn of the primary drbd server

  • default['drbd']['server']['hostname'] = nil - Fqdn of the server
    Note: This will use the node['fqdn'] if not specified.

  • default['drbd']['server']['ipaddress'] = nil - Ipaddress of the server
    Note: This will use node['ipaddress'] if nil.

  • default['drbd']['partner']['hostname'] = nil - Fqdn of the partner server

  • default['drbd']['partner']['ipaddress'] = nil - Ipaddress of the parter server
    Note: If not specified chef will try to search the chef-server using
    node['drbd']['partner']['hostname'] to find the node object.

  • default['drbd']['command_timeout'] = 36000 - A timeout value used when
    trying to create a filesystem of a huge data store.

  • default['drbd']['protocol'] = 'C' - The protocal used by the drbd app.

  • default['drbd']['disk']['on_io_error_action'] = 'detach'

  • default['drbd']['disk']['disk-flushes'] = false

  • default['drbd']['disk']['md-flushes'] = false

  • default['drbd']['disk']['no-disk-barrier'] = false

  • default['drbd']['net']['enabled'] = false

  • default['drbd']['net']['sndbuf-size'] = '1M'

  • default['drbd']['net']['max-buffers'] = 8000

  • default['drbd']['net']['max-epoch-size'] = 8000

  • default['iptables']['enabled'] = true
