# Resource script for Minio
#
# Description: Manages Minio as an OCF resource in
# an Active-Passive High Availability setup.
#
# Author: Ricardo Branco <tsmgeek@gmail.com> : Initial script for minio server

#
#
# usage: $0 {start|stop|status|monitor|validate-all|meta-data}
#
# The "start" arg starts Minio.
#
# The "stop" arg stops it.
#
# OCF parameters:
# OCF_RESKEY_binary
# OCF_RESKEY_conffile
# OCF_RESKEY_pidfile
# OCF_RESKEY_address
# OCF_RESKEY_volumnpaths
