heartbeat is a sophisticated multinode resource manager for High
Availability clusters.

It can failover arbitrary resources, ranging from IP addresses over NFS
to databases that are tied in via resource scripts. The resources can
have arbitrary dependencies for ordering or placement between them.

heartbeat contains a cluster membership layer, fencing, and local and
clusterwide resource management functionality.

1.2/1.0 based 2-node only configurations are supported in a legacy
mode.

heartbeat implements the following kinds of heartbeats:

- Serial ports

- UDP/IPv4 broadcast, multi-cast, and unicast

- IPv4 "ping" pseudo-cluster members.

This package contains the Corosync Cluster Engine Executive, several
default APIs and libraries, default configuration files, and an init
script.

CRM shell is a Pacemaker cluster resource manager command line
interface. It supports Pacemaker configuration, management, and
troubleshooting.

Csync2 is a cluster synchronization tool. It can be used to keep files
on multiple hosts in a cluster in sync. Csync2 can handle complex
setups with much more than just 2 hosts, handle file deletions and can
detect conflicts. It is expedient for HA-clusters, HPC-clusters, COWs
and server farms.

A web-based GUI for managing and monitoring the Pacemaker
High-Availability cluster resource manager.

Libraries and tools that allow applications, particularly filesystems
like OCFS2, to interface with the in-kernel distributed lock manager.

OCFS is the Oracle Cluster File System.

This package contains the core user-space tools needed for creating and
managing the file system.

This package contains the openais executive, openais service handlers,
default configuration files and init script.

Pacemaker is an advanced, scalable High-Availability cluster resource
manager for Linux-HA (Heartbeat) and/or OpenAIS.

It supports "n-node" clusters with significant capabilities for
managing resources and dependencies.

It will run scripts at initialization, when machines go up or down,
when related resources fail and can be configured to periodically check
resource health.

pacemaker-mgmt includes a server/client GUI and a snmp plugin, to help
to manage and monitor pacemaker based HA solution.

Prometheus exporter that scrapes meta information about a running
ceph cluster. All the information gathered from the cluster is done
by interacting with the monitors using an appropriate wrapper over
rados_mon_command(). Hence, no additional setup is necessary other
than having a working ceph cluster.
