Practically everything from moving a resource to deciding which resource to stop in a degraded cluster is achieved by manipulating scores in some way. Scores are calculated per resource and node. Any node with a negative score for a resource can't run that resource. The cluster places a resource on the node with the highest score for it. === Infinity Math === Pacemaker implements +INFINITY+ (or equivalently, ++INFINITY+) internally as a score of 1,000,000. Addition and subtraction with it follow these three basic rules: * Any value + +INFINITY+ = +INFINITY+ * Any value - +INFINITY+ = +-INFINITY+ * +INFINITY+ - +INFINITY+ = +-INFINITY+ [NOTE] ====== What if you want to use a score higher than 1,000,000? Typically this possibility arises when someone wants to base the score on some external metric that might go above 1,000,000. The short answer is you can't. The long answer is it is sometimes possible work around this limitation creatively. You may be able to set the score to some computed value based on the external metric rather than use the metric directly. For nodes, you can store the metric as a node attribute, and query the attribute when computing the score (possibly as part of a custom resource agent). ====== == Deciding Which Nodes a Resource Can Run On == indexterm:[Location Constraints] indexterm:[Resource,Constraints,Location] 'Location constraints' tell the cluster which nodes a resource can run on. There are two alternative strategies. One way is to say that, by default, resources can run anywhere, and then the location constraints specify nodes that are not allowed (an 'opt-out' cluster). The other way is to start with nothing able to run anywhere, and use location constraints to selectively enable allowed nodes (an 'opt-in' cluster). Whether you should choose opt-in or opt-out depends on your personal preference and the make-up of your cluster. If most of your resources can run on most of the nodes, then an opt-out arrangement is likely to result in a simpler configuration. On the other-hand, if most resources can only run on a small subset of nodes, an opt-in configuration might be simpler. === Location Properties === .Properties of a rsc_location Constraint [width="95%",cols="2m,1,<5",options="header",align="center"] |========================================================= |Field |Default |Description |id | |A unique name for the constraint indexterm:[id,Location Constraints] indexterm:[Constraints,Location,id] |rsc | |The name of the resource to which this constraint applies indexterm:[rsc,Location Constraints] indexterm:[Constraints,Location,rsc] |rsc-pattern | |An extended regular expression (as defined in http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_04[POSIX]) matching the names of resources to which this constraint applies, if +rsc+ is not specified; if the regular expression contains submatches and the constraint is governed by a rule (see <>), the submatches can be referenced as +%0+ through +%9+ in the rule's +score-attribute+ or a rule expression's +attribute+ indexterm:[rsc-pattern,Location Constraints] indexterm:[Constraints,Location,rsc-pattern] |node | |A node's name indexterm:[node,Location Constraints] indexterm:[Constraints,Location,node] |score | |Positive values indicate a preference for running the affected resource(s) on this node -- the higher the value, the stronger the preference.

This should normally be left as the default, so that rogue instances of a service can be stopped when they are running where they are not supposed to be. However, there are two situations where disabling resource discovery is a good idea: when a service is not installed on a node, discovery might return an error (properly written OCF agents will not, so this is usually only seen with other agent types); and when Pacemaker Remote is used to scale a cluster to hundreds of nodes, limiting resource discovery to allowed nodes can significantly boost performance. * +always:+ Always perform resource discovery for the specified resource on this node. * +never:+ Never perform resource discovery for the specified resource on this node. This option should generally be used with a -INFINITY score, although that is not strictly required. * +exclusive:+ Perform resource discovery for the specified resource only on this node (and other nodes similarly marked as +exclusive+). Multiple location constraints using +exclusive+ discovery for the same resource across different nodes creates a subset of nodes resource-discovery is exclusive to. If a resource is marked for +exclusive+ discovery on one or more nodes, that resource is only allowed to be placed within that subset of nodes. indexterm:[Resource Discovery,Location Constraints] indexterm:[Constraints,Location,Resource Discovery] |========================================================= [WARNING] ========= Setting resource-discovery to +never+ or +exclusive+ removes Pacemaker's ability to detect and stop unwanted instances of a service running where it's not supposed to be. It is up to the system administrator (you!) to make sure that the service can 'never' be active on nodes without resource-discovery (such as by leaving the relevant software uninstalled). ========= === Asymmetrical "Opt-In" Clusters === indexterm:[Asymmetrical Opt-In Clusters] indexterm:[Cluster Type,Asymmetrical Opt-In] To create an opt-in cluster, start by preventing resources from running anywhere by default: ---- # crm_attribute --name symmetric-cluster --update false ---- Then start enabling nodes.

The following fragment is the equivalent of the above opt-in configuration. .Opt-out location constraints for two resources ====== [source,XML] ------- ------- ====== [[node-score-equal]] === What if Two Nodes Have the Same Score === If two nodes have the same score, then the cluster will choose one. This choice may seem random and may not be what was intended, however the cluster was not given enough information to know any better. .Constraints where a resource prefers two nodes equally ====== [source,XML] ------- ------- ====== In the example above, assuming no other constraints and an inactive cluster, +Webserver+ would probably be placed on +sles-1+ and +Database+ on +sles-2+. It would likely have placed +Webserver+ based on the node's uname and +Database+ based on the desire to spread the resource load evenly across the cluster. However other factors can also be involved in more complex configurations. [[s-resource-ordering]] == Specifying the Order in which Resources Should Start/Stop == indexterm:[Resource,Constraints,Ordering] indexterm:[Resource,Start Order] indexterm:[Ordering Constraints] 'Ordering constraints' tell the cluster the order in which resources should start. [IMPORTANT] ==== Ordering constraints affect 'only' the ordering of resources; they do 'not' require that the resources be placed on the same node.

[[s-resource-colocation]] == Placing Resources Relative to other Resources == indexterm:[Resource,Constraints,Colocation] indexterm:[Resource,Location Relative to other Resources] 'Colocation constraints' tell the cluster that the location of one resource depends on the location of another one. Colocation has an important side-effect: it affects the order in which resources are assigned to a node. Think about it: You can't place A relative to B unless you know where B is. footnote:[ While the human brain is sophisticated enough to read the constraint in any order and choose the correct one depending on the situation, the cluster is not quite so smart. Yet. ] So when you are creating colocation constraints, it is important to consider whether you should colocate A with B, or B with A. Another thing to keep in mind is that, assuming A is colocated with B, the cluster will take into account A's preferences when deciding which node to choose for B. For a detailed look at exactly how this occurs, see http://clusterlabs.org/doc/Colocation_Explained.pdf[Colocation Explained]. [IMPORTANT] ==== Colocation constraints affect 'only' the placement of resources; they do 'not' require that the resources be started in a particular order. If you want resources to be started on the same node 'and' in a specific order, you need both an ordering constraint (see <>) 'and' a colocation constraint, or alternatively, a group (see <>). ==== === Colocation Properties === .Properties of a rsc_colocation Constraint [width="95%",cols="1m,1,<4",options="header",align="center"] |========================================================= |Field |Default |Description |id | |A unique name for the constraint (required). indexterm:[id,Colocation Constraints] indexterm:[Constraints,Colocation,id] |rsc | |The name of a resource that should be located relative to +with-rsc+ (required). indexterm:[rsc,Colocation Constraints] indexterm:[Constraints,Colocation,rsc] |with-rsc | |The name of the resource used as the colocation target.

(For details, see <>.) indexterm:[node-attribute,Colocation Constraints] indexterm:[Constraints,Colocation,node-attribute] |score | |Positive values indicate the resources should run on the same node. Negative values indicate the resources should run on different nodes. Values of \+/- +INFINITY+ change "should" to "must". indexterm:[score,Colocation Constraints] indexterm:[Constraints,Colocation,score] |========================================================= === Mandatory Placement === Mandatory placement occurs when the constraint's score is ++INFINITY+ or +-INFINITY+. In such cases, if the constraint can't be satisfied, then the +rsc+ resource is not permitted to run. For +score=INFINITY+, this includes cases where the +with-rsc+ resource is not active. If you need resource +A+ to always run on the same machine as resource +B+, you would add the following constraint: .Mandatory colocation constraint for two resources ==== [source,XML] ==== Remember, because +INFINITY+ was used, if +B+ can't run on any of the cluster nodes (for whatever reason) then +A+ will not be allowed to run. Whether +A+ is running or not has no effect on +B+. Alternatively, you may want the opposite -- that +A+ 'cannot' run on the same machine as +B+. In this case, use +score="-INFINITY"+. .Mandatory anti-colocation constraint for two resources ==== [source,XML] ==== Again, by specifying +-INFINITY+, the constraint is binding. So if the only place left to run is where +B+ already is, then +A+ may not run anywhere. As with +INFINITY+, +B+ can run even if +A+ is stopped. However, in this case +A+ also can run if +B+ is stopped, because it still meets the constraint of +A+ and +B+ not running on the same node. === Advisory Placement === If mandatory placement is about "must" and "must not", then advisory placement is the "I'd prefer if" alternative. For constraints with scores greater than +-INFINITY+ and less than +INFINITY+, the cluster will try to accommodate your wishes but may ignore them if the alternative is to stop some of the cluster resources. As in life, where if enough people prefer something it effectively becomes mandatory, advisory colocation constraints can combine with other elements of the configuration to behave as if they were mandatory. .Advisory colocation constraint for two resources ==== [source,XML] ==== [[s-coloc-attribute]] === Colocation by Node Attribute === The +node-attribute+ property of a colocation constraints allows you to express the requirement, "these resources must be on similar nodes". As an example, imagine that you have two Storage Area Networks (SANs) that are not controlled by the cluster, and each node is connected to one or the other. You may have two resources +r1+ and +r2+ such that +r2+ needs to use the same SAN as +r1+, but doesn't necessarily have to be on the same exact node. In such a case, you could define a <> named +san+, with the value +san1+ or +san2+ on each node as appropriate. Then, you could colocate +r2+ with +r1+ using +node-attribute+ set to +san+. [[s-resource-sets]] == Resource Sets == 'Resource sets' allow multiple resources to be affected by a single constraint. .A set of 3 resources ==== [source,XML] ---- ---- ==== Resource sets are valid inside +rsc_location+, +rsc_order+ (see <>), +rsc_colocation+ (see <>), and +rsc_ticket+ (see <>) constraints.

[IMPORTANT] ========= If you use a higher-level tool, pay attention to how it exposes this functionality. Depending on the tool, creating a set +A B+ may be equivalent to +A then B+, or +B then A+. ========= === Ordering Multiple Sets === The syntax can be expanded to allow sets of resources to be ordered relative to each other, where the members of each individual set may be ordered or unordered (controlled by the +sequential+ property). In the example below, +A+ and +B+ can both start in parallel, as can +C+ and +D+, however +C+ and +D+ can only start once _both_ +A+ _and_ +B+ are active. .Ordered sets of unordered resources ====== [source,XML] ------- ------- ====== .Visual representation of the start order for two ordered sets of unordered resources image::images/two-sets.png["Two ordered sets",width="13cm",height="7.5cm",align="center"] Of course either set -- or both sets -- of resources can also be internally ordered (by setting +sequential="true"+) and there is no limit to the number of sets that can be specified. .Advanced use of set ordering - Three ordered sets, two of which are internally unordered ====== [source,XML] ------- ------- ====== .Visual representation of the start order for the three sets defined above image::images/three-sets.png["Three ordered sets",width="16cm",height="7.5cm",align="center"] [IMPORTANT] ==== An ordered set with +sequential=false+ makes sense only if there is another set in the constraint. Otherwise, the constraint has no effect. ==== === Resource Set OR Logic === The unordered set logic discussed so far has all been "AND" logic. To illustrate this take the 3 resource set figure in the previous section. Those sets can be expressed, +(A and B) then \(C) then (D) then (E and F)+. Say for example we want to change the first set, +(A and B)+, to use "OR" logic so the sets look like this: +(A or B) then \(C) then (D) then (E and F)+. This functionality can be achieved through the use of the +require-all+ option. This option defaults to TRUE which is why the "AND" logic is used by default. Setting +require-all=false+ means only one resource in the set needs to be started before continuing on to the next set. .Resource Set "OR" logic: Three ordered sets, where the first set is internally unordered with "OR" logic ====== [source,XML] ------- ------- ====== [IMPORTANT] ==== An ordered set with +require-all=false+ makes sense only in conjunction with +sequential=false+. Think of it like this: +sequential=false+ modifies the set to be an unordered set using "AND" logic by default, and adding +require-all=false+ flips the unordered set's "AND" logic to "OR" logic. ==== [[s-resource-sets-colocation]] == Colocating Sets of Resources == Another common situation is for an administrator to create a set of colocated resources. -One way to do this would be to define a resource group (see +The simplest way to do this is to define a resource group (see <>), but that cannot always accurately express the desired -state. +relationships.
