Abstract

The invention provides a method and a device for handling faults. The method includes acquiring information of available memory capacity of storage nodes and the quantities of object storage devices OSD; rejecting OSD addition operation on target storage nodes when ratios of the available memory capacity of the target storage nodes to the quantities of the OSD are smaller than first preset thresholds and setting partial OSD of the target storage nodes in first types of non-working Down states to allow the ratios of the available memory capacity of the target storage nodes to the quantities ofthe other OSD to be larger than or equal to the first preset thresholds. The other OSD refer to the available OSD, except for the partial OSD set in the first types of Down states, among the OSD of the target storage nodes. The method and the device have the advantage that risks of possible OSD performance bottleneck and data recovery failure after faults of memories on the storage nodes occur canbe prevented by the aid of the method and the device.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a fault handling method and device. Background technique [0002] Ceph (Distributed Storage System) is an open source project that provides a software-defined, unified storage solution with the advantages of massive scalability, high performance, and no single point of failure. [0003] A typical Ceph cluster deployment will create an OSD (Object Storage Device, object storage device) for each physical hard disk in the cluster node. [0004] The failure domains of a Ceph cluster usually include disks, nodes (i.e. servers), racks, power circuits, etc. When any component in the fault domain fails, the corresponding OSDs deployed on it will fail, and the Ceph cluster will mark these OSDs as Down (non-working) and perform initialization operations to reorganize the faulty nodes. affected data. [0005] However, it has been found in practice that in the existi...
