Abstract
Apparatus, systems, and methods may operate to detect a failure in a failed one of a plurality of nodes included in a cluster, and to fence a portion of the plurality of nodes, including the failed one. Membership in the portion may be determined according to an aggregated value of weighted values assigned to resources and/or services associated with the cluster. Additional apparatus, systems, and methods are disclosed.
Claims23
An apparatus, comprising:
- a network node including a failure detection module to detect a failure in a failed node of a plurality of nodes included in a cluster;
- and
- a fencing module to fence a portion of the plurality of nodes, including the failed node and at least one other node, wherein membership in the portion of the cluster is determined according to an aggregated value of weighted values respectively assigned to at least one of resources or services associated with the failed node and the at least one other node within the portion of the plurality of nodes included in the cluster.
An apparatus, comprising:
- a first network node in a cluster including a failure detection module to detect a failure in a failed node of a plurality of nodes included in a cluster;
- and
- a second network node in the cluster including a fencing module to fence a portion of the plurality of nodes, including the failed node and at least one other node, wherein membership in the portion of the cluster is determined according to an aggregated value of weighted values respectively assigned to at least one of resources or services associated with the failed node and the at least one other node within the portion of the plurality of nodes included in the cluster.
A processor-implemented method to execute on one or more processors that perform the method, comprising:
- detecting a failure in a failed node of a plurality of nodes included in a cluster;
- and
- fencing a portion of the plurality of nodes, including the failed node and at least one other node, wherein membership in the portion of the cluster is determined according to an aggregated value of weighted values respectively assigned to at least one of resources or services associated with the failed node and the at least one other node within the portion of the plurality of nodes included in the cluster.
A processor-implemented method to execute on one or more processors that perform the method, comprising:
- respectively assigning weighted values to at least one of resources or services associated with a plurality of nodes in a cluster;
- and
- when a failure in a failed node of the plurality of nodes is detected, fencing a first portion of the cluster that includes the failed node and at least one other node, the first portion having a lower aggregated value of the weighted values than a second portion of the cluster that is not fenced.
