Embodiment Construction

[0058] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The 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 shall fall within the protection scope of the present invention.

[0059] Key terms appearing in the present invention are explained below.

[0060] Fault domains, which group nodes that are likely to fail simultaneously by creating fault domains and assigning one or more nodes to them. Failures of all nodes in a single fault domain will be considered the same failure. If fault domains are enacted, m...

Abstract

The invention provides a distributed storage slow disk processing method and system, a terminal and a storage medium, and the method comprises the steps: carrying out the slow disk detection of a distributed storage cluster, and screening and marking a slow disk; judging whether isolation of the marked slow disk exceeds a cluster fault domain or not; if yes, reporting a slow disk fault alarm; and if not, reporting a slow disk fault alarm and isolating the slow disk. According to the method, the detected slow disk is marked, the marked slow disk is subjected to fault domain rule judgment, whether the isolation of the marked slow disk conforms to the fault domain or not is judged, and if not, the fault alarm of the slow disk is generated only, and the slow disk is not isolated; therefore, the situation that the availability of the distributed file system is reduced due to direct isolation of the slow disk can be avoided, the fault expansion of the distributed file system is avoided, and the high availability of the distributed file system can be ensured while the adverse effect of the slow disk in the distributed file system on the system performance is solved.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to a slow disk processing method, system, terminal and storage medium for distributed storage. Background technique [0002] Distributed File System (Distributed File System, DFS) means that the physical storage resources managed by the file system are not necessarily directly connected to the local node, but are connected to the node (which can be simply understood as a computer) through a computer network; or A complete hierarchical file system formed by combining several different logical disk partitions or volume labels. DFS provides a logical tree file system structure for resources distributed anywhere on the network, making it easier for users to access shared files distributed on the network. Individual DFS shared folders act as an access point relative to other shared folders on the network. [0003] Slow disks in the distributed file system refer to hard disk...
