This config option allows syadmins to set pacemaker in maintenance mode which will stop monitoring on the configured resources, so services can be stopped/restarted and pacemaker won't start them again or migrating resources (e.g. virtual IPs).

If True enables IPv6 support. The charm will expect network interfaces
|
|
to be configured with an IPv6 address. If set to False (default) IPv4
|
|
is expected.
|
|
.
|
|
NOTE: these charms do not currently support IPv6 privacy extension. In
|
|
order for this charm to function correctly, the privacy extension must be
|
|
disabled and a non-temporary address must be configured/available on
|
|
your network interface.

This value will become the Corosync authentication key. To generate
|
|
a suitable value use:
|
|
.
|
|
sudo corosync-keygen
|
|
sudo cat /etc/corosync/authkey | base64 -w 0
|
|
.
|
|
This configuration element is mandatory and the service will fail on
|
|
install if it is not provided. The value must be base64 encoded.
|
|
maintenance-mode:
|
|
type: boolean
|
|
default: false
|
|
description: |
|
|
When enabled pacemaker will be put in maintenance mode, this will allow
|
|
administrators to manipulate cluster resources (e.g. stop daemons, reboot
|
|
machines, etc). Pacemaker will not monitor the resources while maintence
|
|
mode is enabled.

type: string
|
|
default: 'False'
|
|
description: |
|
|
Enable resource fencing (aka STONITH) for every node in the cluster.
|
|
This requires MAAS credentials be provided and each node's power
|
|
parameters are properly configured in its inventory.
|
|
maas_url:
|

|
|
The last option should be used in conjunction with the key configuration
|
|
option. Used when service_dns is set on the primary charm for DNS HA.
|
|
cluster_count:
|
|
type: int
|
|
default: 3
|
|
description: |
|
|
Number of peer units required to bootstrap cluster services.
|
|
.
|
|
If less that 3 is specified, the cluster will be configured to
|
|
ignore any quorum problems; with 3 or more units, quorum will be
|
|
enforced and services will be stopped in the event of a loss
|
|
of quorum. It is best practice to set this value to the expected
|
|
number of units to avoid potential race conditions.
|
|
monitor_host:
|
|
type: string
|
|
default:
|
|
description: |
|
|
One or more IPs, separated by space, that will be used as a safety check
|
|
for avoiding split brain situations. Nodes in the cluster will ping these
|
|
IPs periodically. Node that can not ping monitor_host will not run shared
|
|
resources (VIP, shared disk...).
|
|
monitor_interval:
|
|
type: string
|
|
default: 5s
|
|
description: |

description: |

Specifies the corosync.conf network mtu. If unset, the default

corosync.conf value is used (currently 1500). See 'man corosync.conf' for
|
|
detailed information on this config option.

nagios_context:

|
type: string

|
default: "juju"
|
|
description: |
|
|
Used by the nrpe-external-master subordinate charm.
|
|
A string that will be prepended to instance name to set the host name
|
|
in nagios. So for instance the hostname would be something like:
|
|
.
|
|
juju-postgresql-0
|
|
.
|
|
If you're running multiple environments with the same services in them
|
|
this allows you to differentiate between them.
|
|
nagios_servicegroups:
|
|
type: string
|
|
default: ""
|
|
description: |
|
|
A comma-separated list of nagios servicegroups. If left empty, the
