Embodiment Construction

[0052] A method and device for unifying data in a distributed storage system according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0053] It should be clear that the described 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 belong to the protection scope of the present invention.

[0054] In the distributed storage system of the present invention, such as figure 1As shown, it includes multiple Ethernet interface hard disks. Among the multiple Ethernet interface hard disks, one is included as a target Ethernet interface hard disk that needs to receive data sent by the cluster controller. When the link of the target Ethernet interface hard disk is disconnected, the hard disk restarts, or the hard disk sector ...

Abstract

The invention discloses a method for unifying data in a distributed storage system and an Ethernet interface hard disk, which belong to the technical field of computers. It is designed to solve the problem of data inconsistency caused by entering the same storage area. A method for data unification in a distributed storage system, characterized in that it includes: when the target Ethernet interface hard disk is in a failure state, receiving data that needs to be written into the target Ethernet interface hard disk; obtaining clock information; according to the clock information Marking the data, so that when the target Ethernet interface hard disk returns to a normal state, the target Ethernet interface hard disk selects the target data to write into the target Ethernet interface hard disk according to the clock information of multiple sets of data received. target storage area.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for unifying data in a distributed storage system and an Ethernet interface hard disk. Background technique [0002] With the rise of distributed storage systems, the use of hard disks with Ethernet interfaces has gradually become popular. Through the formation of Ethernet interface hard disk clusters among multiple Ethernet interface hard disks, and through the coordination of distributed storage control devices, larger capacity storage services are supported. [0003] Among the multiple Ethernet interface hard disks that constitute a cluster, the Ethernet interface hard disk may partially fail due to link interruption, sector or track damage, etc., and the failed Ethernet interface hard disk is called the target Ethernet interface. hard disk. At this time, the data for the hard disk with the Ethernet interface cannot be stored, and other hard disks with the Etherne...
