The embodiment of the invention provides a disk storage space allocation method and device, equipment and a storage medium. The method comprises the steps of obtaining a data writing request; responding to the data writing request, and obtaining a to-be-written data volume from the data writing request; obtaining an allocation starting address of a disk storage space; in the disk residual space segment linked list, determining a disk residual space segment matched with the to-be-written data volume according to the distribution starting address; allocating the residual space segment of the disk according to the to-be-written data volume, and recording the allocation termination address of the residual space segment of the disk; and updating the allocation starting address to an allocationending address. Through the embodiment of the invention, the allocation effect of the disk storage space can be improved.
Description
technical field [0001] The invention relates to data processing technology in the computer field, in particular to a disk storage space allocation method, device, equipment and storage medium. Background technique [0002] "Reading", "writing", "deleting" and "updating" are the basic data processing performed by data processing equipment on the disk; among them, "writing" includes two data processing processes: the allocation of storage space and the allocation of storage space in the allocated storage space. Write data; and the allocation of storage space will affect the seek time when writing data, and the allocation of storage space is the main factor that generates storage space fragmentation (such as disk fragmentation); therefore, the allocation of storage space is the "write" data processing important part of . [0003] Generally speaking, in order to allocate the storage space in the "write" data processing, the best-adaptive allocation method is usually adopted, th...
