Problems solved by technology

[0003] Because the SolutionMap space is limited and needs to be shared with JRCV (the operation of receiving logs from remote storage devices), when there are many Subblocks (the smallest unit of storage space available for log data) used by JRCV, in order not to interrupt the JRCV process, there will not be enough The Subblock is used by the JETR process, and the JETR queue timeouts because the JETR queue is waiting for the Subblock

Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0037] The embodiment of the present application discloses a storage space management method to avoid JETR operation timeout.

[0038] see figure 1 , a flow chart of a storage space management method shown according to an exemplary embodiment, as shown in figure 1 shown, including:

[0039] S101: judging whether the number of logs received per unit time is greater than the first preset value; if yes, proceed to S102; if not, proceed to S103;

[0040] The execution subject of this embodim...

Abstract

The invention discloses a storage space management method and device, electronic equipment and a computer readable storage medium. The method comprises the steps that whether the number of logs received in unit time is larger than a first preset value or not is judged; if yes, interrupting the target operation; wherein the target operation is an operation of expanding the log from a storage spaceto a disk. The invention provides a storage space management method. When the number of the logs received in unit time is greater than a first preset value; in the prior art, the JRCV needs to use more Subblocks, and the Subblocks are insufficient, so that the operation of expanding the log from the storage space to the disk is interrupted, and the situation that the whole Journal Replication function is unavailable due to overtime JETR operation is avoided.

Description

technical field [0001] The present application relates to the field of storage technology, and more specifically, to a storage space management method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] In the Journal Replication (log-based data backup) function, when the Journal (the log of data flow sent by the host to the storage device) reaches the remote data storage device through the remote data backup function, the SolutionMap space (allocated to The storage space of the log data) creates a JETR (the operation of expanding the log data from the storage space to the disk) queue, and then expands the Journal to the disk of the storage device. [0003] Because the SolutionMap space is limited and needs to be shared with JRCV (the operation of receiving logs from remote storage devices), when there are many Subblocks (the smallest unit of storage space available for log data) used by JRCV, in order not to interrupt the ...
