Abstract

The invention discloses a data storage method and device, a storage medium and electronic equipment. The method comprises the steps that under the condition that a target storage sector distributed for current data to be stored is located in a damaged sector list, a current mapping partition in a storage area is obtained, and the storage area further comprises a storage partition where the target storage sector is located; under the condition that the current storage time of the current data is within a preset time interval corresponding to the current mapping partition, a target mapping sector is determined from the current mapping partition; and the current data is stored in the target mapping sector. The technical problem that the front-end data cannot be mapped and stored due to the fact that the storage space of the mapping area cannot be released in time is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data storage method and device, a storage medium and electronic equipment. Background technique [0002] In the current distributed storage cluster in the video surveillance scenario, the business pressure from the front-end camera will always exist since the project is deployed. Therefore, the storage cluster is required to provide safe and reliable continuous writing capabilities, so as to avoid front-end video and pictures. Phenomena that can be preserved in time appear. [0003] However, during the use of the mechanical hard disk in the data node, some sectors may be damaged due to the aging of the storage medium, external interference and other reasons. At this time, it is necessary to find a section of storage space of the same size for the bad sectors that cannot be written in the data node through software means, so as to ensure that the front-end data is placed on the...
