What is a resource?

See resource[1] page.

Enabling the Cluster Resource Manager

The information you need is in ClusterResourceManager/Setup[2].

Converting your 1.x (haresources) configuration

The information you need is in ClusterInformationBase/Conversion[3]. However please make sure you first read ClusterInformationBase/SimpleExamples[4] and ClusterInformationBase/ResourceGroups[5] otherwise it will make no sense to you at all.

Grouping resources

The information you need is in ClusterInformationBase/ResourceGroups[5]. However please make sure you first read ClusterInformationBase/SimpleExamples[4] otherwise it will make no sense to you at all.

Preventing a resource from running on a specific node

The information you need is in ClusterInformationBase/SimpleExamples[4], Section 2.4.2[6].

Applying a constraint to a group of nodes

The information you need is in ClusterInformationBase/UsingAttributes[7], Section 1[8].

Running resources on the master node

See CIB/Idioms/ColoWithMaster[9]

Running a master/slave resource's master on a specific node

See CIB/Idioms/MasterConstraints[10]

What's up with +/- INFINITY?

See ScoreCalculation[11]

Score Calculation

See ScoreCalculation[11]
