Abstract

The invention discloses a memory fault processing method and device and a computer readable storage medium, and relates to the technical field of computers. The method comprises the steps of obtaining redundant space of a memory by monitoring fault information of the memory of a server, and judging whether the redundant space is smaller than a first threshold value or not; if not, obtaining a fault physical memory address and a corresponding virtual memory address according to the fault information; isolating the faulted physical memory address through a redundancy mechanism of the memory, and obtaining a new physical memory address; and backing up the data in the fault physical memory address, and mapping the virtual memory address to a new physical memory address so as to migrate the data to the new physical memory address. Therefore, according to the scheme, the fault memory is permanently isolated through a redundancy mechanism, meanwhile, the mapping position of the virtual memory is changed to isolate a software level in the fault memory, and data in the fault memory is not lost; the downtime rate caused by memory faults is effectively reduced, unnecessary memory replacement is reduced, and the operation and maintenance cost is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a memory fault processing method, device and computer-readable storage medium. Background technique [0002] Server memory is also memory (RAM), with some unique technologies, such as error checking and correction (ErrorCorrecting Code, ECC), etc., so it has extremely high stability and error correction performance. However, all current modern operating systems do not directly access physical memory when accessing server memory, but through an intermediate layer, which is called virtual memory (Virtual Memory, VM) in the operating system; , to access the corresponding physical memory mapped by the VM. At the same time, the physical memory address of the virtual memory mapping can also be changed, so that the operating system can access the physical memory address. [0003] However, in the operation and use of servers, server hardware fault diagnosis and fault predic...
