NAME

ocf_heartbeat_lxc - Manages LXC containers

SYNOPSIS

lxc [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

Allows LXC containers to be managed by the cluster. Notes for lxc Versions before 1.0.0, where the Container is stopped using kill -PWR instead of lxc-stop: It is 'assumed' that the 'init' system will do an orderly shudown if presented with a 'kill -PWR' signal. On a 'sysvinit' this would require the container to have an inittab file containing "p0::powerfail:/sbin/init 0"

SUPPORTED PARAMETERS

(unique, required, string, no default)

config

(optional, string, default "/var/run/resource-agents/RESOURCE_ID.log")

use_screen

Provides the option of capturing the 'root console' from the container and showing it on a separate screen. To see the screen output run 'screen -r {container name}' The default value is set to 'false', change to 'true' to activate this option

(optional, boolean, default false)
