inheritance	leaf > head
scope order	specific > generic

A whitespace-separated list of conditions to meet to accept running a “provision” action. A condition is expressed as <rid>(<state>,...). If states are omitted, up,stdby up is used as the default expected states.

push_schedule

scopable	True
required	False
provisioning	False
default	~00:00-06:00
inheritance	leaf > head
scope order	specific > generic

The service configuration emission to the collector schedule. See usr/share/doc/schedule for the schedule syntax.

registry_creds

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf > head
scope order	specific > generic

The name of a secret in the same namespace having a config.json key which value is used to login to the container image registry. If not specified, the node-level registry credential store is used.

resinfo_schedule

scopable	True
required	False
provisioning	False
default	@60
inheritance	leaf > head
scope order	specific > generic

The service resource info push schedule. See usr/share/doc/schedule for the schedule syntax.

restart

scopable	True
required	False
provisioning	False
default	0
inheritance	leaf > head
scope order	specific > generic
convert	integer

The agent will try to restart a resource <n> times before falling back to the monitor action. A resource restart is triggered if :the resource is not disabled and its status is not up, and the node is not frozen, and the service instance is not frozen and its local expect is set to started. If a resource has a restart set to a value >0, its status is evaluated at the frequency defined by DEFAULT.monitor_schedule instead of the frequency defined by DEFAULT.status_schedule. restart_delay defines the interval between two restarts. Standby resources have a particular value to ensure best effort to restart standby resources, default value is 2, and value lower than 2 are changed to 2.

restart_delay

scopable	True
required	False
provisioning	False
default	0
inheritance	leaf > head
scope order	specific > generic
convert	duration

Define minimum delay between two triggered restarts of a same resource (used when :kw:`restart`is defined). Default value is 0 (no delay).

rollback

scopable	True
required	False
provisioning	False
default	True
inheritance	leaf > head
scope order	specific > generic
convert	boolean

If set to false, the default “rollback on action error” behaviour is inhibited, leaving the service in its half-started state. The daemon also refuses to takeover a service if rollback is disabled and a peer instance is “start failed”.

run_requires

scopable	True
required	False
provisioning	False
default
inheritance	leaf > head
scope order	specific > generic

A whitespace-separated list of conditions to meet to accept running a “run” action. A condition is expressed as <rid>(<state>,...). If states are omitted, up,stdby up is used as the default expected states.

run_schedule

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf > head

default	None
inheritance	head
scope order	specific > generic
convert	integer

convert	boolean

Automatically set to true by the daemon monitor when creating new scaler slaves.

scsireserv

scopable	True
required	False
provisioning	False
default	False
inheritance	leaf > head
scope order	specific > generic
candidates	True | False
convert	boolean

If set to true, OpenSVC will try to acquire a type-5 (write exclusive, registrant only) scsi3 persistent reservation on every path to disks of every disk group attached to this service. Existing reservations are preempted to not block service start-up. If the start-up was not legitimate the data are still protected from being written over from both nodes. If set to false or not set, scsireserv can be activated on a per-resource basis.

shared

scopable	True
required	False
provisioning	False
default	False
inheritance	leaf > head
scope order	specific > generic
candidates	True | False
convert	boolean

Set to true to skip the resource on provision and unprovision actions if the action has already been done by a peer. Shared resources, like vg built on SAN disks must be provisioned once. All resources depending on a shared resource must also be flagged as shared.

show_disabled

required	False
provisioning	False
default	True
inheritance	head
scope order	specific > generic
candidates	True | False
convert	boolean

Specifies if the disabled resources must be included in the print status and json status output.

soft_anti_affinity

scopable	True
required	False
provisioning	False
default	set()
inheritance	head
scope order	specific > generic
convert	set

A whitespace separated list of services that must not be started on the node to allow the monitor to start this service. If the local node is the only candidate ignore this constraint and allow start.

standby

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf > head
scope order	specific > generic
convert	tristate

Always start the resource, even on standby instances. The daemon is responsible for starting standby resources. A resource can be set standby on a subset of nodes using keyword scoping.

A typical use-case is sync’ed fs on non-shared disks: the remote fs must be mounted to not overflow the underlying fs.

Avertissement

Don’t set shared resources standby: fs on shared disks for example.

start_requires

inheritance	leaf > head
scope order	specific > generic

The mecanism is enforced by a timestamp created upon each sync completion in <pathvar>/services/<namespace>/<kind>/<name>/<rid>/last_sync_<node>

sync_max_delay

scopable	False
required	False
provisioning	False
default	1d3h
inheritance	leaf > head

scope order	specific > generic
convert	set

A list of tags. Arbitrary tags can be used to limit action scope to resources with a specific tag. Some tags can influence the driver behaviour. For example noaction avoids any state changing action from the driver and implies optional=true, nostatus forces the status to n/a.
