Embodiment Construction

[0047] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0048] The embodiments of the present invention are applicable to a distributed storage system, where the distributed storage system includes a plurality of storage devices, and the storage devices are, for example, a computer and a server, including a processor and a storage medium. In this embodiment of the present invention, a storage device may also be called a node. And each node belongs to at least one group. The nodes belonging to the same group have the same function or belong to the same physical area. It should be noted that during the upgrade process of a node, the business that is being executed on the node needs to be executed by other nodes, and in general, the unexecuted business will be transferred to the node with the same function for completion, so as to ensure the busin...

Abstract

Embodiments of the present invention provide a distributed storage system upgrade management method, device and distributed storage system, which can solve the problem of low upgrade efficiency of the distributed storage system. The distributed storage system includes multiple nodes, and each node belongs to at least one group. The method includes: the scheduling node obtains the constraint conditions of each group in the distributed storage system; the scheduling node determines the first upgrade plan according to the constraint conditions of each group; Send upgrade instructions. Wherein, the constraints include the maximum number of nodes allowed to be upgraded in parallel in each group, and the first upgrade scheme includes: dividing multiple nodes into at least one batch, and the nodes in each batch satisfy each constraint. The embodiment of the present invention is applicable to a distributed storage system.

Description

technical field [0001] Embodiments of the present invention relate to the field of storage technologies, and in particular, to a method, an apparatus, and a distributed storage system for upgrade management of a distributed storage system. Background technique [0002] Distributed storage system, which dispersely stores data on multiple independent devices, adopts a scalable system structure, and uses these multiple independent devices to share the storage load, which can not only improve the reliability, performance and capacity of the storage system, but also Easy to expand. At present, the common architectures of distributed storage systems include: figure 1 The scale-up architecture shown and as figure 2 The scale-out architecture shown. Among them, the scale-up architecture refers to that, in the original storage system, the capacity of a single device is increased or the device is updated to meet the growth requirements of data and performance (that is, a storage c...
