Values for [all:vars] in the Ansible Configuration File

The Ansible configuration file includes a section named [all:vars], which specifies values for many keys.

Note

Do not comment-out any of the keys in this section, even if you do not enter a value for them.

Key name	Description and possible values
admin_addr	email address of the administrator to receive alerts
cluster_name	any unique name in the current environment
custom_drive_map	(optional) an absolute file path to a drive map file used for drive initialization on Hedvig nodes. For example, /home/admin/cluster_node.map. If custom drive sizes, partitions, or assignments are desired, this variable should specify the path to the file that contains the required information in the required format.
datacenter_field	index (which starts with 0) of the data center field in the cluster node hostname. For example: `host1.rack1.dc1.hedviginc.com` `0 1 2 3 4` In this case, you would set the value to 2. The requirement for this field depends on the replication_policy value: DataCenterAware – required RackAware – required RackUnaware (agnostic) – optional (defaults to 0)
dns_available	True (default) – All hostnames are resolvable using nslookup. False – The /etc/hosts file must be populated.
dual_dc	True – The setup is dual data center. False – The setup is not dual data center (default).
email_interval	(optional) values of xh where x = the number of hours (default is 1h)
enable_server_side_flache	True/False – Enables server-side caching for data.
from_addr	email address from which notifications are sent
hyperconverged_setup	True – The setup is hyperconverged. False – The setup is not hyperconverged (default).
latencyaware	True – The setup is latency aware. False – The setup is not latency aware (default).
lsitype	lsijbod (default) – LSI controller in JBOD mode megaraid – LSI controller in RAID mode hpraid – HP storage controller in RAID mode
mail_addr	email address to which notifications are sent
ntp_server	NTP server hostname address
use_ntp	True – Use the NTP server to sync time across cluster machines. False – Use the deployment server's current time to set the time for the cluster machines (default).
rack_field	index (which starts with 0) of the rack field in the cluster node hostname. For example: `host1.rack1.dc1.hedviginc.com` `0 1 2 3` In this case, you would set the value to 1. The requirement for this field depends on the replication_policy: DataCenterAware – required RackAware – required RackUnaware (Agnostic) – optional (defaults to 0)
replication_factor	2, 3 (default), or 4
replication_policy	RackUnaware (also known as agnostic) (default) DataCenterAware RackAware
smtp_host	SMTP (simple mail transfer protocol) server hostname address
storage_interface	network interface to use for deployment By default, the deployment server has one interface (eth0). If the environment has multiple networks (storage, management), add more VNICs to the deployment server, configure it, and make sure the interface with full access to the cluster nodes is specified (for example, eth1).
timeseries_name	For use with the Pensieve service, the <Customer Display Name>
timeseries_webserver	For use with the Pensieve service, the <Webserver Hostname>:8080
timezone	appropriate tz database time zone (default is US/Pacific) For a list of tz database time zones, select 2 when deploying a new cluster to view the Ansible configuration file format.
transfer_hosts	True – Transfers a copy of the /etc/hosts file from the deployment server to all storage cluster nodes. False (default) – If the cluster is not being deployed as DNS available, all hostnames must be in the /etc/hosts file.
