NAME¶

ClusterTools2 - Tools for setting up and managing pacemaker HA clusters

DESCRIPTION¶

The ClusterTools2 package provides tools for setting up and managing pacemaker HA clusters. The tools are aimed to make tasks easy around the pacemaker HA cluster manager and the Linux storage stack.

Main command for managing a running cluster is ClusterService. This ASCII-terminal based menu system allows to perform common administrative tasks. It can be used instead of crm_gui or Hawk if no webservice and no X desktop is available.

Tools like cs_list_failcounts and cs_show_cluster_transistion help to analyse the cluster behaviour. A set of tools based on wow allows to make configuration of clusters reproduceable and efficiant.

Currently the tools are mainly used to setup and manage high-availability cluster for following workloads:

- SAP application servers, SAP central instances, SAP database servers

- SAP HANA System Replication automation

- XEN virtual machine hosts

- Novell eDirectory servers

- NFS file servers

- Apache web servers, LAMP servers

- MySQL, PostgreSQL, DB2, Oracle database servers

EXAMPLES¶

# wow cc --config edir01.wow 01-A-07-group_add_ndsd

add configuration for a resource of type Novell eDirectory to the cluster. Use configuration agent 01-A-07-group_add_ndsd. Read information about the resource from file edir01.wow .

# cs_precheck_for_sap --all sap_C11.wow >precheck-sap_C11-$HOST

check for allmost all pre-requistes that are needed to set up an HA cluster for SAP instance C11. Read information about the needed resources from file sap_C11.wow . Write output into file precheck-sap_C11-<hostname>.

# ClusterService

start ASCII-terminal based menu to perform administrative tasks on a running cluster.

# cs_sum_base_config >$HOST.cs_sum_base_config.txt

write checksums for common base config files of an node to a file. This is useful in a cluster, to check if the basic configuration is really identical on both nodes.

# cs_list_clone_files --md5sum

look for files that should not be identical, after a VM image was cloned.
