Description
The monitoring daemon runs
nanny
on the active LVS router. Through this
daemon, the active LVS router
determines the health of each real
server and, optionally, monitors its
workload. A separate process runs for
each service defined on each real
server.
This is the LVS configuration file. The
full path for the file is
/etc/sysconfig/ha/lvs.cf
or indirectly, all daemons get their
configuration information from this file.
This is the Web-based tool for
monitoring, configuring, and
administering LVS. This is the default
tool to maintain the
/etc/sysconfig/ha/lvs.cf
configuration file.
This program sends out ARP
broadcasts when the floating IP
address changes from one node to
another during failover.
A disk-based quorum daemon for
CMAN / Linux-Cluster.
Cluster Quorum Disk Utility.
