<p>An Ansible role for managing High Availability Clustering.</p>
<h1 id="limitations">Limitations</h1>
<ul>
<li>Compatible OS
<ul>
<li>RHEL 8.3+, Fedora 31+</li>
<li>SLES 15 SP5+ with HA extension, SLES4SAP 15 SP5+</li>
</ul></li>
<li>Systems running RHEL are expected to be registered and have
High-Availability repositories accessible, and ResilientStorage
repositories accessible if using
<code>ha_cluster_enable_repos_resilient_storage</code></li>
<li>The role replaces the configuration of HA Cluster on specified
nodes. Any settings not specified in the role variables will be
lost.</li>
<li>The role is capable of configuring:
<ul>
<li>single-link or multi-link cluster</li>
<li>Corosync transport options including compression and encryption</li>
<li>Corosync totem options</li>
<li>Corosync quorum options</li>
<li>Corosync quorum device (both qnetd and qdevice)</li>
<li>SBD</li>
<li>Pacemaker cluster properties</li>
<li>stonith and resources</li>
<li>resource defaults and resource operation defaults</li>
<li>stonith levels, also known as fencing topology</li>
<li>resource constraints</li>
<li>Pacemaker node attributes</li>
<li>Pacemaker Access Control Lists (ACLs)</li>
<li>node and resource utilization</li>
<li>Pacemaker Alerts</li>
</ul></li>
</ul>
<h1 id="requirements">Requirements</h1>
<p>See below</p>
<h2 id="collection-requirements">Collection requirements</h2>
<p>The role requires the <code>firewall</code> role and the
<code>selinux</code> role from the
<code>fedora.linux_system_roles</code> collection, if
<code>ha_cluster_manage_firewall</code> and
<code>ha_cluster_manage_selinux</code> is set to true, respectively.
Please see also <a
href="#ha_cluster_manage_firewall"><code>ha_cluster_manage_firewall</code></a>
and <a
href="#ha_cluster_manage_selinux"><code>ha_cluster_manage_selinux</code></a>.</p>
<p>If the <code>ha_cluster</code> is a role from the
<code>fedora.linux_system_roles</code> collection or from the Fedora RPM
package, the requirement is already satisfied.</p>
<p>If you need to manage <code>rpm-ostree</code> systems, you will need
to install additional collections. Please run the following command line
to install the collections.</p>
<div class="sourceCode" id="cb1"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="ex">ansible-galaxy</span> collection install <span class="at">-r</span> meta/collection-requirements.yml</span></code></pre></div>
<h1 id="role-variables">Role Variables</h1>
<h2 id="defined-in-defaultsmainyml">Defined in
<code>defaults/main.yml</code></h2>
<h3
id="ha_cluster_enable_repos"><code>ha_cluster_enable_repos</code></h3>
<p>boolean, default: <code>true</code></p>
<p>RHEL and CentOS only, enable repositories containing needed
packages</p>
<h3
id="ha_cluster_enable_repos_resilient_storage"><code>ha_cluster_enable_repos_resilient_storage</code></h3>
<p>boolean, default: <code>false</code></p>
<p>RHEL and CentOS only, enable repositories containing resilient
storage packages, such as dlm or gfs2. For this option to take effect,
<code>ha_cluster_enable_repos</code> must be set to
<code>true</code>.</p>
<h3
id="ha_cluster_manage_firewall"><code>ha_cluster_manage_firewall</code></h3>
<p>boolean, default: false</p>
<p>Manage the <code>firewall high-availability service</code> as well as
the <code>fence-virt port</code>. When
<code>ha_cluster_manage_firewall</code> is <code>true</code>, the
<code>firewall high-availability service</code> and
<code>fence-virt port</code> are enabled. When
<code>ha_cluster_manage_firewall</code> is <code>false</code>, the
<code>ha_cluster role</code> does not manage the firewall.</p>
<p>NOTE: <code>ha_cluster_manage_firewall</code> is limited to
<em>adding</em> ports. It cannot be used for <em>removing</em> ports. If
you want to remove ports, you will need to use the firewall system role
directly.</p>
<p>NOTE: The version of the <code>ha_cluster</code> role is 1.7.5 or
older, the firewall was configured by default if the firewalld was
available when the <code>ha_cluster</code> role was executed. In the
newer version, it does not happen unless
<code>ha_cluster_manage_firewall</code> is set to <code>true</code>.</p>
<h3
id="ha_cluster_manage_selinux"><code>ha_cluster_manage_selinux</code></h3>
<p>boolean, default: false</p>
<p>Manage the ports belonging to the
<code>firewall high-availability service</code> using the selinux role.
When <code>ha_cluster_manage_selinux</code> is <code>true</code>, the
ports belonging to the <code>firewall high-availability service</code>
are associated with the selinux port type <code>cluster_port_t</code>.
When <code>ha_cluster_manage_selinux</code> is <code>false</code>, the
<code>ha_cluster role</code> does not manage the selinux.</p>
<p>NOTE: The firewall configuration is prerequisite for managing
selinux. If the firewall is not installed, managing selinux policy is
skipped.</p>
<p>NOTE: <code>ha_cluster_manage_selinux</code> is limited to
<em>adding</em> policy. It cannot be used for <em>removing</em> policy.
If you want to remove policy, you will need to use the selinux system
role directly.</p>
<h3
id="ha_cluster_cluster_present"><code>ha_cluster_cluster_present</code></h3>
<p>boolean, default: <code>true</code></p>
<p>If set to <code>true</code>, HA cluster will be configured on the
hosts according to other variables. If set to <code>false</code>, all HA
Cluster configuration will be purged from target hosts.</p>
<h3
id="ha_cluster_start_on_boot"><code>ha_cluster_start_on_boot</code></h3>
<p>boolean, default: <code>true</code></p>
<p>If set to <code>true</code>, cluster services will be configured to
start on boot. If set to <code>false</code>, cluster services will be
configured not to start on boot.</p>
<h3
id="ha_cluster_install_cloud_agents"><code>ha_cluster_install_cloud_agents</code></h3>
<p>boolean, default: <code>false</code></p>
<p>The role automatically installs needed HA Cluster packages. However,
resource and fence agents for cloud environments are not installed by
default on RHEL. If you need those to be installed, set this variable to
<code>true</code>. Alternatively, you can specify those packages in <a
href="#ha_cluster_fence_agent_packages"><code>ha_cluster_fence_agent_packages</code></a>
and <a
href="#ha_cluster_extra_packages"><code>ha_cluster_extra_packages</code></a>
variables.</p>
<h3
id="ha_cluster_fence_agent_packages"><code>ha_cluster_fence_agent_packages</code></h3>
<p>list of fence agent packages to install, default: fence-agents-all,
fence-virt</p>
<h3
id="ha_cluster_extra_packages"><code>ha_cluster_extra_packages</code></h3>
<p>list of additional packages to be installed, default: no packages</p>
<p>This variable can be used to install additional packages not
installed automatically by the role, for example custom resource
agents.</p>
<p>It is possible to specify fence agents here as well. However, <a
href="#ha_cluster_fence_agent_packages"><code>ha_cluster_fence_agent_packages</code></a>
is preferred for that, so that its default value is overridden.</p>
<h3
id="ha_cluster_hacluster_password"><code>ha_cluster_hacluster_password</code></h3>
<p>string, no default - must be specified</p>

<p>If no key is specified, a key already present on the nodes will be
used. If nodes don't have the same key, a key from one node will be
distributed to other nodes so that all nodes have the same key. If no
node has a key, a new key will be generated and distributed to the
nodes.</p>
<p>If this variable is set, <code>ha_cluster_regenerate_keys</code> is
ignored for this key.</p>
<h3
id="ha_cluster_pacemaker_key_src"><code>ha_cluster_pacemaker_key_src</code></h3>
<p>path to Pacemaker authkey file, default: <code>null</code></p>
<p>Authentication and encryption key for Pacemaker communication. It is
highly recommended to have a unique value for each cluster. The key
should be 256 bytes of random data.</p>
<p>If value is provided, it is recommended to vault encrypt it. See <a

<p>If this variable is set, <code>ha_cluster_regenerate_keys</code> is
ignored for this key.</p>
<h3
id="ha_cluster_fence_virt_key_src"><code>ha_cluster_fence_virt_key_src</code></h3>
<p>path to fence-virt or fence-xvm pre-shared key file, default:

<code>ha_cluster_pcsd_private_key_src</code></h3>
<p>path to pcsd TLS certificate and key, default: <code>null</code></p>
<p>TLS certificate and private key for pcsd. If this is not specified, a
certificate - key pair already present on the nodes will be used. If
certificate - key pair is not present, a random new one will be
generated.</p>
<p>If private key value is provided, it is recommended to vault encrypt
it. See <a
href="https://docs.ansible.com/ansible/latest/user_guide/vault.html">https://docs.ansible.com/ansible/latest/user_guide/vault.html</a>
for details.</p>
<p>If these variables are set, <code>ha_cluster_regenerate_keys</code>
is ignored for this certificate - key pair.</p>
<h3
id="ha_cluster_pcsd_certificates"><code>ha_cluster_pcsd_certificates</code></h3>
<p>If there is no pcsd private key and certificate, there are two ways
to create them.</p>
<p>One way is by setting <code>ha_cluster_pcsd_certificates</code>
variable. Another way is by setting none of <a
href="#ha_cluster_pcsd_public_key_src-ha_cluster_pcsd_private_key_src"><code>ha_cluster_pcsd_public_key_src</code>
and <code>ha_cluster_pcsd_private_key_src</code></a> and
<code>ha_cluster_pcsd_certificates</code>.</p>
<p>If <code>ha_cluster_pcsd_certificates</code> is provided, the
<code>certificate</code> role is internally used and it creates the
private key and certificate for pcsd as defined. If none of the
variables are provided, the <code>ha_cluster</code> role will create
pcsd certificates via pcsd itself.</p>
<p>The value of <code>ha_cluster_pcsd_certificates</code> is set to the
variable <code>certificate_requests</code> in the
<code>certificate</code> role. For more information, see the
<code>certificate_requests</code> section in the
<code>certificate</code> role documentation.</p>
<p>The default value is <code>[]</code>.</p>
<p>NOTE: The <code>certificate</code> role, unless using IPA and joining
the systems to an IPA domain, creates self-signed certificates, so you
will need to explicitly configure trust, which is not currently
supported by the system roles.</p>
<p>NOTE: When you set <code>ha_cluster_pcsd_certificates</code>, you
must not set <code>ha_cluster_pcsd_public_key_src</code> and
<code>ha_cluster_pcsd_private_key_src</code> variables.</p>
<p>NOTE: When you set <code>ha_cluster_pcsd_certificates</code>,
<code>ha_cluster_regenerate_keys</code> is ignored for this certificate
- key pair.</p>
<h3
id="ha_cluster_regenerate_keys"><code>ha_cluster_regenerate_keys</code></h3>
<p>boolean, default: <code>false</code></p>
<p>If this is set to <code>true</code>, pre-shared keys and TLS

<p>Watchdog and SBD devices can be configured on a node to node basis in
two variables:</p>
<ul>
<li><a
href="#ha_cluster_node_options"><code>ha_cluster_node_options</code></a>
is a single variable expected to have the same value for all cluster
nodes. It is a list of dictionaries, each dictionary defines options for
one node.</li>
<li><a href="#sbd-watchdog-and-devices"><code>ha_cluster</code></a>
dictionary defines options for one node only. To set different values
for each node, you define the variable separately for each node.</li>

<p>This variable defines various settings which vary from cluster node
to cluster node.</p>
<p><strong>Note:</strong> Use an inventory or playbook hosts to specify
which nodes form the cluster. This variable merely sets options for the
specified nodes.</p>
<p>The items are as follows:</p>
<ul>
<li><code>node_name</code> (mandatory) - Node name. It must match a name
defined for a node. See also <a
href="#nodes-names-and-addresses"><code>ha_cluster.node_name</code></a>.</li>
<li><code>pcs_address</code> (optional) - Address used by pcs to
communicate with the node, it can be a name, a FQDN or an IP address.
Port can be specified as well.</li>
<li><code>corosync_addresses</code> (optional) - List of addresses used
by Corosync, all nodes must have the same number of addresses and the
order of the addresses matters.</li>
<li><code>sbd_watchdog_modules</code> (optional) - Watchdog kernel
modules to be loaded (creates <code>/dev/watchdog*</code> devices).
Defaults to empty list if not set.</li>
<li><code>sbd_watchdog_modules_blocklist</code> (optional) - Watchdog
kernel modules to be unloaded and blocked. Defaults to empty list if not
set.</li>
<li><code>sbd_watchdog</code> (optional) - Watchdog device to be used by
SBD. Defaults to <code>/dev/watchdog</code> if not set.</li>
<li><code>sbd_devices</code> (optional) - Devices to use for exchanging
SBD messages and for monitoring. Defaults to empty list if not set.
Always refer to the devices using the long, stable device name
(<code>/dev/disk/by-id/</code>).</li>
<li><code>attributes</code> (optional) - List of sets of Pacemaker node
attributes for the node. Currently, only one set is supported, so the
first set is used and the rest are ignored.</li>
<li><code>utilization</code> (optional) - List of sets of the node's
utilization. The field <code>value</code> must be an integer. Currently,
only one set is supported, so the first set is used and the rest are
ignored.</li>

<p>This variable defines Pacemaker resources (including stonith)
configured by the role. The items are as follows:</p>
<ul>
<li><code>id</code> (mandatory) - ID of a resource.</li>
<li><code>agent</code> (mandatory) - Name of a resource or stonith
agent, for example
<!--- wokeignore:rule=dummy -->
<code>ocf:pacemaker:Dummy</code> or <code>stonith:fence_xvm</code>. It
is mandatory to use <code>stonith:</code> for stonith agents. For
resource agents, it is possible to use a
<!--- wokeignore:rule=dummy -->
short name, such as <code>Dummy</code> instead of
<code>ocf:pacemaker:Dummy</code>. However, if several agents with the
same short name are installed, the role will fail as it will be unable
to decide which agent should be used. Therefore, it is recommended to
use full names.</li>
<li><code>instance_attrs</code> (optional) - List of sets of the
resource's instance attributes. Currently, only one set is supported, so
the first set is used and the rest are ignored. The exact names and
values of attributes, as well as whether they are mandatory or not,
depends on the resource or stonith agent.</li>
<li><code>meta_attrs</code> (optional) - List of sets of the resource's
meta attributes. Currently, only one set is supported, so the first set
is used and the rest are ignored.</li>
<li><code>copy_operations_from_agent</code> (optional) - Resource agents
usually define default settings for resource operations (e.g. interval,
timeout) optimized for the specific agent. If this variable is set to
<code>true</code>, then those settings are copied to the resource
configuration. Otherwise, clusterwide defaults will apply to the
resource. You may want to set this to <code>false</code> if you also
define <a href="#ha_cluster_resource_operation_defaults">resource
operation defaults</a> for the resource. Defaults to
<code>true</code>.</li>
<li><code>operations</code> (optional) - List of the resource's
operations.
<ul>
<li><code>action</code> (mandatory) - Operation action as defined by
Pacemaker and the resource or stonith agent.</li>
<li><code>attrs</code> (mandatory) - Operation options, at least one
option must be specified.</li>
</ul></li>
<li><code>utilization</code> (optional) - List of sets of the resource's
utilization. The field <code>value</code> must be an integer. Currently,
