# There are lots of options in this file. 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 all of debugfile, logfile and logfacility are not defined,
|
||||
# logging is the same as use_logd yes. In other case, they are
|
||||
# respectively effective. if detering the logging to syslog,
|
||||
# logfacility must be "none".

# auto_failback: determines whether a resource will
|

# automatically fail back to its "primary" node, or remain
|
||||
# on whatever node is serving it until that node fails, or
|
||||
# an administrator intervenes.
|
||||
#
|
||||
# The possible values for auto_failback are:
|
||||
# on - enable automatic failbacks
|
||||
# off - disable automatic failbacks
|
||||
# legacy - enable automatic failbacks in systems
|
||||
# where all nodes do not yet support

# the auto_failback option.
|

#
|

# auto_failback "on" and "off" are backwards compatible with the old

# from "legacy" to "on" without a flash cut.

#
|

# The default value for auto_failback is "legacy", which

# will issue a warning at startup. So, make sure you put

# an auto_failback directive in your ha.cf file.

# Basic STONITH support
|

# Using this directive assumes that there is one stonith
|
||||
# device in the cluster. Parameters to this device are
|
||||
# read from a configuration file. The format of this line is:
|
||||
#
|
||||
# stonith <stonith_type> <configfile>
|
||||
#
|
||||
# NOTE: it is up to you to maintain this file on each node in the
|
||||
# cluster!

#
|
||||
#stonith baytech /etc/ha.d/conf/stonith.baytech
|
||||
#
|
||||
# STONITH support
|
||||
# You can configure multiple stonith devices using this directive.
|
||||
# The format of the line is:
|
||||
# stonith_host <hostfrom> <stonith_type> <params...>
|
||||
# <hostfrom> is the machine the stonith device is attached
|
||||
# to or * to mean it is accessible from any host.
|
||||
# <stonith_type> is the type of stonith device (a list of
|
||||
# supported drives is in /usr/lib/stonith.)
|
||||
# <params...> are driver specific parameters. To see the
|
||||
# format for a particular device, run:
|
||||
# stonith -l -t <stonith_type>
|
||||
#
|
||||
#
|
||||
# Note that if you put your stonith device access information in
|
||||
# here, and you make this file publically readable, you're asking
|
||||
# for a denial of service attack ;-)
|
||||
#
|
||||
# To get a list of supported stonith devices, run
|
||||
# stonith -L
|
||||
# For detailed information on which stonith devices are supported
|
||||
# and their detailed configuration options, run this command:
|
||||
# stonith -h
