Embodiment Construction

[0037] In order to facilitate the understanding of various aspects, features and advantages of the technical solutions of the present invention, the present invention will be specifically described below in conjunction with the accompanying drawings. It should be understood that the various implementations described below are only for illustration, rather than limiting the protection scope of the present invention.

[0038] Figure 1A It is a block diagram of a system for performing fault analysis on a Ceph-based object storage system according to an embodiment of the present invention. As shown in FIG. 1 , the system may include a front-end device (referred to as "front-end") and a back-end server (referred to as "back-end"), and the front-end device and the back-end server may be connected through a network.

[0039] The front-end equipment includes a failure impact query module 110, which is used to perform the following operations: obtain an ip-osd list, an osd-pg list, an...

Abstract

The invention discloses a system and a medium for fault analysis of a Ceph-based object storage system, and relates to the technical field of computer application. The system comprises front-end equipment and a rear-end server, and the rear-end server obtains osd and pg lists of a cluster from an object storage system after receiving a request of the front-end equipment for obtaining the osd and pg lists; the osd list and the pg list are processed to obtain an ip-osd list, an osd-pg list and an ip-pg list, and the ip-osd list, the osd-pg list and the ip-pg list are returned to the front-end equipment; and the front-end equipment displays the ip-osd list on a front-end page, inquires influenced pg from the ip-pg list or osd-pg list according to two fault node IPs or disk IDs input by operation and maintenance personnel, and displays the influenced pg on the front-end page. The influence range and the migration recovery time can be quickly judged when the node or the disk fails, and theworking efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a system and a storage medium for fault analysis of a Ceph-based object storage system. Background technique [0002] Ceph is a reliable, automatic rebalancing, and automatic recovery distributed storage system. According to the scene division, Ceph can be divided into three major blocks, namely object storage, block device storage and file system service. [0003] The core components of Ceph include: OSD, full name Object Storage Device, responsible for the process of returning specific data in response to client requests, a Ceph cluster has many OSDs; Monitor, a Ceph cluster requires a small cluster composed of multiple Monitors, which are synchronized through Paxos Data, used to save the metadata of OSD; Object is the lowest storage unit of Ceph, each Object contains metadata and original data; PG, full name Placement Groups, is a logical concept, a PG co...
