Problems solved by technology

All nodes in the HANA cluster can operate on the data and log volumes of other nodes. With the increase in the number of nodes in the HANA cluster, it is more difficult for technicians to operate and maintain the actual process, and data disks may be damaged due to misoperation. Data Loss Scenarios

Abstract

The invention discloses a disk misoperation method for preventing HANA cluster, comprising the following steps: generating a key corresponding to each working node, and writing the key into the LUN header file corresponding to the volume under each working node respectively ; In response to the work node receiving the operation request to the volume, the operation request is converted into an operation command and the key corresponding to the work node is added to the operation command; The operation command after adding the key Send to the underlying storage and compare the key; in response to the key in the operation command being different from the key in the LUN header file corresponding to the volume to be operated, do not operate the volume to be operated and report an error. The invention also discloses a system, a computer device and a readable storage medium. The solution proposed by the present invention can not only realize the method of preventing the misoperation of data disks under other nodes, but also can effectively solve the problem of human misoperation of the disks, and can also ensure the disaster tolerance of the HANA cluster.

Description

technical field [0001] The present invention relates to the field of HANA clusters, in particular to a method, system, device and storage medium for preventing misoperation of disks in HANA clusters. Background technique [0002] Building a HANA cluster with multiple servers can meet larger memory requirements and at the same time achieve disaster recovery of HANA cluster nodes. However, in order to achieve disaster recovery of HANA cluster nodes, all nodes need to be able to access all shared disk volume groups. like figure 1 As shown, the HANA cluster shown in the figure includes 3+1 nodes (3 worker nodes, one standby node), each worker node has its own data and log volumes, when any one of the worker nodes (here is host2) ) generates an abnormal state, and host4 (standby node) can take over the data volume and log volume corresponding to any faulty node. After the failed node is repaired, it also needs to be able to access the disk volumes shared by all other nodes. F...
