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 method for preventing disk misoperation of an HANA cluster, which comprises the following steps: generating a key corresponding to each working node, and writing the key intoan LUN header file corresponding to a volume under each working node; responding to a volume operation request received by the working node, converting the operation request into an operation command, and adding a key corresponding to the working node into the operation command; sending the operation command added with the key to a bottom layer for storage, and comparing the key; and in responseto the fact that the key in the operation command is different from the key in the LUN header file corresponding to the volume to be operated, not operating the volume to be operated and reporting anerror. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, a method for preventing misoperation on the data disk under other nodes can be realized, the problem of manual misoperation of the disk can be effectively solved, and the disaster tolerance of the HANA cluster can also be ensured.

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 disk misoperation of HANA clusters. Background technique [0002] Constructing a HANA cluster with multiple servers can satisfy larger memory, and at the same time, it can realize HANA cluster node disaster recovery. However, in order to achieve disaster recovery of HANA cluster nodes, all nodes need to be able to access all shared disk volume groups. Such as figure 1 As shown, the HANA cluster shown in the figure includes 3+1 nodes (3 working nodes, one standby node), each working node has its own data and log volume, when any of the working nodes (here is host2 ) to generate an abnormal state, host4 (standby node) can take over the data volume and log volume corresponding to any failed node. After the failed node is repaired, it also needs to be able to access the shared disk volumes of all other nodes. For the ...
