# This script manages the LVS synchronisation daemon

# Please note that as of 2.4.29, this is no longer needed
12
# as both the master and backup daemon can run simultaneously
14
# usage: $0 {master|backup} {interface} {start|stop|status|monitor|cleanup}
16
# The first argument, master or backup, is the YING.
17
# The YANG is internally calculated to be which ever or master and
20
# e.g $0 LVSSyncDaemonSwap master start # YING=master YANG=backup
21
# $0 LVSSyncDaemonSwap backup start # YING=backup YANG=master
24
# "start" will stop the YANG if it is running and starts the YING
25
# "stop" will stop the YING if it is running and starts the YANG
26
# "cleanup" is a non-standard target stop the YING if it is running
27
# an stop the YANG if it is running
