AMF.CONF(5)AMF.CONF(5)NAMEamf.conf - corosync AMF configuration file
DESCRIPTIONamf.conf is the configuration file that determines the behaviour of the
AIS Availability Management Framework service, AMF in the corosync
implementation.
Entries in this file will for example determine what applications AMF
will start and how to supervise them.
By default AMF opens /etc/ais/amf.conf. The environment variable OPE‐
NAIS_AMF_CONFIG_FILE can be set to the pathname of an AMF configuration
file to override the default behaviour.
Any line whose first non-white-space character is a '#' is considered a
comment line. Empty lines are ignored.
The file contains object entries of the form:
<Object Class> = <Object Name> {
<attribute> = <value>
...
}
Object entries are nested, one entry contains another entry. This way
relations between objects are built up. For example a component object
defined inside a Software Unit (SU) object means that the component
belongs to the SU. In other words, the SU is composed of the component.
See the example configuration file.
The relation between objects has to comply with the AMF model specified
in [5].
Object names shall use only printable ASCII characters. Object names
shall be unique within its context, i.e. two components within the same
service unit has to have different names, but can have the same name as
another component within another service unit.
Attribute names are consistent with the naming of the configuration
attributes in [5].
AMF object attributes are either configuration or runtime attributes.
The AMF configuration file is used to specify configuration attributes.
Some configuration attributes have default values and does not need to
be specified. Others are not valid in certain redundancy models and so
on.
The type of an attribute value is either a string, a number, a time or
an enumeration. Enumeration values are specified according to the type
definition in the AIS specification. Time values are specified in mil‐
liseconds.
Multivalue attributes are specified using multiple entries with the
same attribute name but different values. See the example configuration
file.
The (RDN) value of 'safAmfNode' is a logical name for an AMF node. It
is mapped to a real physical node using the attribute 'saAmfNode‐
ClmNode'.
The value of the attribute 'saAmfNodeClmNode' should be the hostname
(without domain name) as given to the host at boot time. This name is
returned by the shell command 'hostname'.
Currently, AMF is enabled/disabled by an entry in the corosync.conf
file, see [1]. It is default disabled.
The following list of attributes is currently supported:
safAmfCluster
