5.3. Resource Properties

Aceste valori îi spun clusterului care script să îl folosească pentru resursă, unde să găsească acel script şi care sunt standardele la care acesta aderă.

Tabel 5.1. Proprietăţile unei Resurse Primitive

Câmp	Descriere
`id`	Your name for the resource
`class`	The standard the script conforms to. Allowed values: `ocf`, `service`, `upstart`, `systemd`, `lsb`, `stonith`
`type`	The name of the Resource Agent you wish to use. Eg. IPaddr or Filesystem
`provider`	The OCF spec allows multiple vendors to supply the same ResourceAgent. To use the OCF resource agents supplied with Heartbeat, you should specify `heartbeat` here.

Resource definitions can be queried with the crm_resource tool. For example

# crm_resource --resource Email --query-xml

might produce:

Exemplu 5.1. An example system resource

<primitive id="Email" class="service" type="exim"/>

Notă

One of the main drawbacks to system services (such as LSB, Systemd and Upstart) resources is that they do not allow any parameters!

Exemplu 5.2. Un exemplu de resursă OCF

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
   <instance_attributes id="params-public-ip">
      <nvpair id="public-ip-addr" name="ip" value="1.2.3.4"/>
   </instance_attributes>
</primitive>
