Virtual node subpool management

摘要

Virtual file system virtual nodes are grouped in subpools in response to identified resource components and managed as a function of their subpool groupings. Virtual nodes are decomposed into individual components linked to each other within each node. The components that have repetitive accesses by applications within the virtual file system and their respective frequencies of repetitive access are identified. Modules of linked occurrences of the repetitive components within each of the plurality of virtual nodes are formed, and subsets of the virtual nodes sharing common modules are grouped into subpools. Accordingly, in response to an application of the virtual file system requesting a service that is satisfied by a subpool common module, selection of a virtual node for reinitiating for reuse by the application is restricted to virtual nodes within the subpool associated with the common module.

1. A method for managing virtual nodes in response to identified component access frequencies, the method comprising:
ordering individual components decomposed from each of a plurality of virtual nodes within a virtual file system and linked to each other within the virtual nodes into root components as a function of the root components having at least three accesses by applications within the virtual file system, and of having highest frequencies of accesses by the applications relative to others of the individual components; progressively depending others of the individual components that have at least three accesses from the roots as a function of having frequencies of the accesses by the applications that are lower than the highest frequencies of accesses; omitting the individual components that each have less than three accesses by the applications; and in response to an application of the virtual file system requesting a service that is satisfied by an inactive one of the virtual nodes, selecting the inactive virtual node and reinitiating the selected inactive virtual node for reuse by the application by locating, quiescing and returning the root components decomposed from the selected inactive virtual node and the others of the individual components progressively depending from the root components decomposed from the selected inactive virtual node, without quiescing the omitted components and any others of the components that are not decomposed from the selected inactive virtual node.
