Abstract

The embodiment of the present invention discloses a hard disk fault domain detection method, device, and computer-readable storage medium. According to the obtained fault domain name corresponding to the target node, all OSD service numbers included in the target node are obtained, and the obtained OSD service numbers are The OSD Service ID that this fault domain theoretically contains. The number list stored in the system records the OSD service number actually mounted on the target node, that is, the actual number. It is judged in turn whether each OSD service number contained in the target node matches the actual number included in the number list; if there is an OSD service number that does not match the actual number, an alarm prompt is given. This technical solution improves the alarm mechanism of Ceph, realizes the detection of the fault domain to which the hard disk belongs, and actively sends an alarm after the problem is found, further protects the redundancy mechanism of Ceph, and prevents cluster nodes from being damaged due to artificial modification or misoperation. Data loss due to corruption.

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...
