Quorum Parameters List

The table below lists the Quorum parameters. These values are tuned by editing the /etc/default/LifeKeeper configuration file.

Parameter Name	Meaning	Setting Value	Default Value	When to Apply	Notes
QUORUM_MODE	Specifies the quorum mode.	majority tcp_remote storage none or off	majority	As required	Refer to "Quorum/Witness" in SIOS Technical Documentation.
QUORUM_HOSTS	Specifies a host and port name combination to be used for determining quorum. The format for entries is "host:port". When specifying more than one host:port combination, the entries must be comma separated (do not include a space). (Example) QUORUM_HOSTS=myhost:80,router1:443,router2:22	String	(not set)	As required	This parameter is applied only when the QUORUM_MODE is tcp_remote.
WITNESS_MODE	Specifies the witness mode.	remote_verify storage none or off	remote_verify	As required	Refer to "Quorum/Witness" in SIOS Technical Documentation.
QUORUM_TIMEOUT_SECS	The time allowed for tcp/ip witness connections to complete. Connections that don't complete within this time are treated as failed/unavailable. This only applies when the QUORUM_MODE is tcp_remote.	Integers	20	As required	This parameter is applied only when the QUORUM_MODE is tcp_remote.
QUORUM_LOSS_ACTION	Specifies the action when quorum is lost.	fastkill fastboot osu	fastkill	As required	Refer to "Quorum/Witness" in SIOS Technical Documentation.
QWK_STORAGE_TYPE	Specifies the type of shared storage. Must be specified when QUORUM_MODE is storage.	block file aws_s3	(not set)	When executing `qwk_storage_init`	This parameter is applied only when storage is specified for QUORUM_MODE and WITNESS_MODE. For details, see "Storage Mode" in the Technical Documentation.
QWK_STORAGE_HBEATTIME	Specifies the interval in seconds between reading and writing the QWK objects.	An integer between 5 and 10	6	When executing `qwk_storage_init`	This parameter is applied only when storage is specified for QUORUM_MODE and WITNESS_MODE. For details, see "Storage Mode" in the Technical Documentation.
QWK_STORAGE_NUMHBEATS	Specifies the number of consecutive heartbeat checks that when reached indicates the target node has failed. A missed heartbeat occurs when the QWK object has not been updated since the last check.	An integer of 3 or more	4	When executing `qwk_storage_init`	This parameter is applied only when storage is specified for QUORUM_MODE and WITNESS_MODE. For details, see "Storage Mode" in the Technical Documentation.
QWK_STORAGE_OBJECT_<Host name> Note: If the host name contains a "-" or ".", replace them with an underscore "_" (e.g. lksios-1 `→` lksios_1). Note: The host name used by LifeKeeper can be checked via the lcduname command	Specifies the path to the QWK objects. You must specify paths for all nodes in the cluster. [When QWK_STORAGE_TYPE is block] Specify the device file path. (Example) QWK_STORAGE_OBJECT_nodeA=/dev/sdx QWK_STORAGE_OBJECT_nodeB=/dev/sdy [When QWK_STORAGE_TYPE is file] Specify the regular file path. (Example) QWK_STORAGE_OBJECT_nodeA=/quorum/nodeA QWK_STORAGE_OBJECT_nodeB=/quorum/nodeB [When QWK_STORAGE_TYPE is aws_s3] Specify the S3uri for the Amazon S3 object. Use an S3 object from a different region than the one where LifeKeeper is running. It is also recommended that 2 different S3 objects be used and that they reside in different regions. When specifying 2 regions, make sure to separate them with commas(do not include spaces). (Example 1) QWK_STORAGE_OBJECT_nodeA=s3://bucket1/nodeA,s3://bucket2/nodeA QWK_STORAGE_OBJECT_nodeB=s3://bucket1/nodeB,s3://bucket2/nodeB (Example 2) QWK_STORAGE_OBJECT_nodeA=s3://bucket/quorum/nodeA QWK_STORAGE_OBJECT_nodeB=s3://bucket/quorum/nodeB	String (Maximum length is 256 characters)	(not set)	When executing `qwk_storage_init`	This parameter is applied only when storage is specified for QUORUM_MODE and WITNESS_MODE. For details, see "Storage Mode" in the Technical Documentation.
HTTP_PROXY HTTPS_PROXY NO_PROXY	Set this parameter when using HTTP proxy for accessing the service endpoint. The value set here will be passed to AWS CLI. See AWS Documentation for details.	String	(not set)	When executing `qwk_storage_init`	This is a common parameter for "EC2" and "Route53.
QUORUM_DEBUG	Specifies the debug mode.	0: disabled 1: enabled	0	As required	Refer to "Quorum/Witness" in SIOS Technical Documentation.
