All you have to have is a set # of nodes listed {"node ...} one of {serial, bcast, mcast, or ucast}, # and a value for "auto_failback". # # ATTENTION: As the configuration file is read line by line, # THE ORDER OF DIRECTIVE MATTERS! # # In particular, make sure that the udpport, serial baud rate # etc. are set before the heartbeat media are defined! # debug and log file directives go into effect when they # are encountered. # # All will be fine if you keep them ordered as in this example. # # # Note on logging: # If any of debugfile, logfile and logfacility are defined then they # will be used. If debugfile and/or logfile are not defined and # logfacility is defined then the respective logging and debug # messages will be loged to syslog. If logfacility is not defined # then debugfile and logfile will be used to log messges. If # logfacility is not defined and debugfile and/or logfile are not # defined then defaults will be used for debugfile and logfile as # required and messages will be sent there. # # File to write debug messages to debugfile /var/log/ha-debug # # # File to write other messages to # logfile /var/log/ha-log # # # Facility to use for syslog()/logger # logfacility local0 # # # A note on specifying "how long" times below... # # The default time unit is seconds # 10 means ten seconds # # You can also specify them in milliseconds # 1500ms means 1.5 seconds # # # keepalive: how long between heartbeats? # keepalive 2 # # deadtime: how long-to-declare-host-dead? # # If you set this too low you will get the problematic # split-brain (or cluster partition) problem. # See the FAQ for how to use warntime to tune deadtime. # deadtime 30 # # warntime: how long before issuing "late heartbeat" warning? # See the FAQ for how to use warntime to tune deadtime. # warntime 10 # # # Very first dead time (initdead) # # On some machines/OSes, etc. the network takes a while to come up # and start working right after you've been rebooted.
