The method further includes identifying a similar characteristic across the first plurality of storage devices and the second plurality of storage devices. The method further includes generating a task to be performed by at least one of the first management device or the second management device based on the similar characteristic. The method further includes causing at least one of the first management device or the second management device to perform the task.

Description

BACKGROUND The present disclosure relates to computing environments, and more specifically, to processing namespace range information by a global coordinator. Computing devices communicate data, process data, and/or store data. Such computing devices range from wireless smart phones, laptops, tablets, personal computers (PC), work stations, and video game devices, to data centers that support millions of web searches, stock trades, or on-line purchases every day. In general, a computing device includes a central processing unit (CPU), a memory system, user input/output interfaces, peripheral device interfaces, and an interconnecting bus structure. A computing device may effectively extend its CPU by using “cloud computing” to perform one or more computing functions (e.g., a service, an application, an algorithm, an arithmetic logic function, etc.) on behalf of the computing device. Further, for large services, applications, and/or functions, cloud computing may be performed by multiple cloud computing resources in a distributed manner to improve the response time for completion of the service, application, and/or function. For example, Hadoop is an open-source software framework that supports distributed applications, enabling application execution by hundreds or thousands of computers. In addition to cloud computing, a computing device may use “cloud storage” as part of its memory system. Cloud storage enables a user, via its computing device, to store files, applications, etc., on an Internet-based storage system. The Internet-based storage system may include a RAID (redundant array of independent disks) system and/or a dispersed storage system that uses an error correction scheme to encode data for storage. SUMMARY According to an embodiment, a computer-implemented method for identifying and visualizing namespace range gaps is provided. The method includes receiving, at a global coordinator from a first management device, first namespace information for each of a first plurality of storage devices managed by the first management device, the first namespace information being shared among the first plurality of storage devices. The method further includes receiving, at the global coordinator from a second management device, second namespace information for each of a second plurality of storage devices managed by the second management device, the second namespace information being shared among the second plurality of storage devices. The method further includes identifying a similar characteristic across the first plurality of storage devices and the second plurality of storage devices. The method further includes generating a task to be performed by at least one of the first management device or the second management device based on the similar characteristic. The method further includes causing at least one of the first management device or the second management device to perform the task. Other embodiments described herein implement features of the above-described method in computer systems and computer program products. The above features and advantages, and other features and advantages, of the disclosure are readily apparent from the following detailed description when taken in connection with the accompanying drawings.
