Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Next, a method for detecting a fault domain of a hard disk provided by an embodiment of the present invention is introduced in detail. figure 1 It is a flow chart of a hard disk fault domain d...

Abstract

The embodiment of the invention discloses a hard disk failure domain detection method and device and a computer readable storage medium. According to failure domain names corresponding to obtained target nodes, all OSD service numbers contained in the target nodes are obtained, and the obtained OSD service numbers are OSD service numbers theoretically contained in the failure domain. A numbered list stored in the system records the OSD service numbers actually mounted on the target node, and the OSD service numbers are actual numbers. Whether or not all the OSD service numbers contained in thetarget nodes are matched with the actual numbers contained in the numbered list is judged in sequence; if the OSD service number which are not matched with the actual numbers exist, alarm prompting is conducted. Accordingly, an alarm mechanism of Ceph is perfected, detection on failure domains belonging to a hard disk is achieved, alarm is given actively after problems are found, a redundancy mechanism of the Ceph is further protected, and the phenomenon that due to artificial modification or misoperation, cluster nodes are damaged, and then data is lost is avoided.

Description

technical field [0001] The invention relates to the technical field of distributed file systems, in particular to a hard disk fault domain detection method, device and computer-readable storage medium. Background technique [0002] The Distributed File System (Ceph) is a new generation of free software distributed file system designed by Sage Weil (co-founder of DreamHost) at the University of California, Santa Cruz for his doctoral dissertation. The main goal of Ceph is to design a POSIX-based distributed file system without a single point of failure, enabling data to be fault-tolerant and seamlessly replicated, and is a software-defined storage system. Software Defined Storage (Software Defined Storage, SDS) is a data storage method, all storage-related control work is only in the external software relative to the physical storage hardware. Object Storage Device (OSD) is a service unit for storing data in SDS. This service is established on the hard disk and corresponds t...
