# galera_gcomm.rb

# Purpose: Return 'true' if gcomm:// cluster address is empty for Galera MySQL master-master replication engine
#
# Resolution:
# Greps mysql config files for wsrep_cluster_address option
#
# Caveats:
#
## Cfkey.rb
## Facts related to cfengine

#
# [*cluster_name*]
# Cluster name for `wsrep_cluster_name` variable.

# [*primary_controller*]
# Set to true if current node is the initial master/primary

#
# [*node_address*]
# Which value to use as node address for filtering in gcomm address.
# This is done due to some bugs in galera configuration. Thus we are

#
# [*setup_multiple_gcomm*]
# Should gcomm address contain multiple nodes or not.
#
# [*skip_name_resolve*]
# By default, MySQL tries to do reverse name mapping IP->hostname. In this
# case MySQL requests can be timed out by clients in case of broken name
# resolving system. If you are not sure that your DNS/NIS/whatever are configured
# correctly, set this value to true.
