comment

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

Helps users understand the role of the service and resources, which is nice to on-call support people having to operate on a service they are not usually responsible for.

disable

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

A disabled resource will be ignored on service startup and shutdown. Its status is always reported n/a.

Set in DEFAULT, the whole service is disabled. A disabled service does not honor start and stop actions. These actions immediately return success.

om <path> disable only sets DEFAULT.disable. As resources disabled state is not changed, om <path> enable does not enable disabled resources.

encap

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

Set to true to ignore this resource in the nodes context and consider it in the encapnodes context. The resource is thus handled by the agents deployed in the service containers.

monitor

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

A down monitored resource will trigger a node suicide if the monitor thinks it should be up and the resource can not be restarted.

optional

scopable	True
required	False
provisioning	False
default	true for tasks, syncs and resources tagged ‘noaction’, else false
inheritance	leaf > head
scope order	specific > generic
convert	tristate

Action failures on optional resources are logged but do not stop the action sequence. Also the optional resource status is not aggregated to the instance ‘availstatus’, but aggregated to the ‘overallstatus’. Resource tagged noaction and sync resources are automatically considered optional. Useful for resources like dump filesystems for example.

pg_blkio_weight

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf
scope order	specific > generic
depends	create_pg in [True]
convert	integer

pg_cpu_quota

provisioning	False
default	None
inheritance	leaf
scope order	specific > generic
depends	create_pg in [True]

The percent ratio of one core to allocate to the process group if % is specified, else the absolute value to set in the process group parameter. For example, on Linux cgroups, -1 means unlimited, and a positive absolute value means the number of microseconds to allocate each period. 50%@all means 50% of all cores, and 50%@2 means 50% of two cores.

pg_cpu_shares

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf
scope order	specific > generic
depends	create_pg in [True]
convert	integer

Kernel default value is used, which usually is 1024 shares. In a cpu-bound situation, ensure the service does not use more than its share of cpu ressource. The actual percentile depends on shares allowed to other services.

pg_cpus

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf
scope order	specific > generic
depends	create_pg in [True]

Allow service process to bind only the specified cpus. Cpus are specified as list or range : 0,1,2 or 0-2

pg_mem_limit

required	False
provisioning	False

inheritance	leaf
scope order	specific > generic
depends	create_pg in [True]
convert	size

Ensures the service does not use more than specified memory (in bytes). The Out-Of-Memory killer get triggered in case of tresspassing.

pg_mem_oom_control

scopable	True
required	False
provisioning	False
default	None
inheritance	leaf
scope order	specific > generic
depends	create_pg in [True]
convert	integer

A flag (0 or 1) that enables or disables the Out of Memory killer for a cgroup. If enabled (0), tasks that attempt to consume more memory than they are allowed are immediately killed by the OOM killer. The OOM killer is enabled by default in every cgroup using the memory subsystem; to disable it, write 1.

pg_mem_swappiness

scopable	True

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

provision_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 ‘provision’ action. A condition is expressed as <rid>(<state>,...). If states are omitted, up,stdby up is used as the default expected states.

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.

shared

scopable	True

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.

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.

Warning

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