 == Simplify administration using a cluster shell ==
 
 In the dark past, configuring Pacemaker required the administrator to
 read and write XML.  In true UNIX style, there were also a number of
 different commands that specialized in different aspects of querying
 and updating the cluster.
 
 All of that has been greatly simplified with the creation of unified
 command-line shells (and GUIs) that hide all the messy XML
 scaffolding.
 
 These shells take all the individual aspects required for managing and
 configuring a cluster, and pack them into one simple-to-use command
 line tool.
 
 They even allow you to queue up several changes at once and commit
 them atomically.
 
 Two popular command-line shells are `pcs` and
 `crmsh`.  This edition of Clusters from Scratch is based on `pcs`.
 
 [NOTE]
 ===========
 The two shells share many concepts but the scope, layout and syntax
 does differ, so make sure you read the version of this guide that
 corresponds to the software installed on your system.
 ===========
 
-[IMPORTANT]
-===========
-Since `pcs` has the ability to manage all aspects of the cluster (both
-corosync and pacemaker), it requires a specific cluster stack to be in
-use: corosync 2.0 or later with votequorum plus Pacemaker 1.1.8 or later.
-===========

 == Explore pcs ==
 
 Start by taking some time to familiarize yourself with
 what `pcs` can do.
 
 ----
 [root@pcmk-1 ~]# pcs
 Usage: pcs [-f file] [-h] [commands]...
 Control and configure pacemaker and corosync.
 
 Options:
     -h, --help  Display usage and exit
     -f file     Perform actions on file instead of active CIB
     --debug     Print all network traffic and external commands run
     --version   Print pcs version information
 
 Commands:
     cluster     Configure cluster options and nodes
     resource    Manage cluster resources
     stonith     Configure fence devices
     constraint  Set resource constraints
     property    Set pacemaker properties
     acl         Set pacemaker access control lists
     status      View cluster status
     config      View and manage cluster configuration
 ----
 
 As you can see, the different aspects of cluster management are separated
 into categories: resource, cluster, stonith, property, constraint,
 and status. To discover the functionality available in each of these
 categories, one can issue the command +pcs pass:[<replaceable>category</replaceable>] help+.  Below
 is an example of all the options available under the status category.
 
 ----
 [root@pcmk-1 ~]# pcs status help
 Usage: pcs status [commands]...
 View current cluster and resource status
 Commands:
     [status] [--full]
         View all information about the cluster and resources (--full provides
         more details)
 
     resources
         View current status of cluster resources
 
     groups
         View currently configured groups and their resources
 
     cluster
         View current cluster status
 
     corosync
         View current membership information as seen by corosync
 
     nodes [corosync|both|config]
         View current status of nodes from pacemaker. If 'corosync' is
         specified, print nodes currently configured in corosync, if 'both'
         is specified, print nodes from both corosync & pacemaker.  If 'config'
         is specified, print nodes from corosync & pacemaker configuration.
 
     pcsd <node> ...
         Show the current status of pcsd on the specified nodes
 
     xml
         View xml version of status (output from crm_mon -r -1 -X)
 ----
 
 Additionally, if you are interested in the version and
 supported cluster stack(s) available with your Pacemaker
 installation, run:
 
 ----
 [root@pcmk-1 ~]# pacemakerd --features
 Pacemaker 1.1.12 (Build: a14efad)
  Supporting v3.0.9:  generated-manpages agent-manpages ascii-docs publican-docs ncurses libqb-logging libqb-ipc upstart systemd nagios  corosync-native atomic-attrd acls

 [NOTE]
 ======
 If the SNMP and/or email options are not listed, then Pacemaker was not
 built to support them. This may be by the choice of your distribution, or
 the required libraries may not have been available. Please contact
 whoever supplied you with the packages for more details.
