STORAGE MASTER NODE

摘要

Technology is provided for selecting a master node of a node group in a storage system. The technology can gather data regarding visibility of one or more storage devices of the storage system to one or more active nodes of the node group, determine a maximum visibility value for the node group and selecting an active node with associated visibility value equal to the maximum visibility value as the master node of the node group.

1. A method of selecting a master node of a node group in a storage system, comprising:
gathering data regarding visibility of one or more storage devices of the storage system to one or more active nodes of the node group, wherein a storage device of the one or more storage devices is visible to a selected active node of the one or more active nodes when the storage device is accessible to the active node through at least one functioning data communications path in the storage system; determining a maximum visibility value for the node group, wherein a visibility value of the selected active node is determined as a function of a total number of storage devices visible to the selected active node; and selecting as the master node of the node group an active node having the maximum visibility value.
