Method, device, device and medium for collecting log information of problem disk of ssd

Abstract

Embodiments of the present invention disclose a method, apparatus, device and computer-readable storage medium for collecting log information of a problem disk of an NVME SSD. The method includes pre-setting the interface of all solid-state hard disks with the function of sending their own serial numbers through corresponding PCIE devices, obtaining the serial numbers responded by the corresponding NVME devices of each solid-state hard disk in the current server under normal operation, and generating a first sequence Number set; generate the second serial number set according to the serial numbers actively sent by all solid-state drives in the server through the corresponding PCIE device; if the number of serial numbers contained in the first serial number set and the second serial number set is different, the first serial number set The serial number set and the second serial number set locate the target serial numbers of the problem disks; the PCIE devices corresponding to the target serial numbers are polled and searched respectively, and a log collection command is issued to obtain the log information of each problem disk. The present application realizes the effective and rapid collection of log information of problem disks without affecting other normal disks.

Description

technical field [0001] The present disclosure relates to the technical field of fault detection of solid-state hard disks, and in particular, to a method, apparatus, device, and computer-readable storage medium for collecting log information of problem disks of NVME SSDs. Background technique [0002] With the rapid development of the Internet and cloud technologies, data has exploded, and the corresponding data storage technologies are also facing severe challenges. In the era of big data, the storage of massive data plays an increasingly important role. While the speed of computing components such as CPU is getting higher and higher, data storage has become a bottleneck for system performance improvement. Solid State Drive (SSD) is widely used due to its fast read and write speed, low energy consumption, and the gradual decline of NAND prices. [0003] NVME (Non-Volatile Memory Express, non-volatile memory host controller interface specification) hard disk is a type of ha...

Problems solved by technology

Corresponding to this application scenario, if one or several disks in the SSD cluster fail, related technologies are usually based on the NVME upper layer protocol to realize fault location or troubleshooting, but this method will not only affect the use of other normal disks; Moreover, if the NVME device corresponding to the faulty disk is lost, the fault location cannot be realized based on the NVME protocol.
