Problems solved by technology

When a server in a distributed system is damaged and needs to be replaced with a new server, generally the disks on the damaged server are intact and the data on the disk is also complete, but when the disk with data on the damaged server is When plugged into a new server, these disks are considered as new data disks, and the data originally stored on the disks are considered to be invalid data. It is necessary to start the data recovery mechanism of the system to restore the data originally stored on the disks. Format the data first and then restore the data. Obviously, this method will lead to a large amount of data recovery inside the system, which will not only reduce the external performance of the entire system, but also cause a large number of data reads and writes. It may cause damage to other available disks and cause disasters. sexual consequences

Abstract

The invention discloses a data processing method which is applied to a node maintenance server, and the method comprises the steps: obtaining at least one piece of first identification information transmitted by a new node under the condition that the new node is detected to be added, wherein the first identification information is the identification information corresponding to memories includedin the new node; respectively matching the at least one piece of first identification information with a plurality of pieces of second identification information in a pre-stored identification set toobtain a matching result; and sending a control instruction to the new node according to the matching result, and when the control instruction at least carries first type information, using the control instruction for indicating the new node to carry out data formatting on a memory corresponding to first identification information which fails to be matched with the second identification information in the matching result, wherein the first type information represents first identification information which fails to be matched with the second identification information. The invention further discloses the electronic equipment.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data processing method and electronic equipment. Background technique [0002] A distributed system is a software system built on top of a network. When a server in a distributed system is damaged and needs to be replaced with a new server, generally the disks on the damaged server are intact and the data on the disk is also complete, but when the disk with data on the damaged server is When plugged into a new server, these disks are considered as new data disks, and the data originally stored on the disks are considered to be invalid data. It is necessary to start the data recovery mechanism of the system to restore the data originally stored on the disks. Format the data first and then restore the data. Obviously, this method will lead to a large amount of data recovery inside the system, which will not only reduce the external performance of the entire system, but also cause a ...
