Abstract

The embodiment of the invention discloses a data processing method and device; when a client carries out a plurality of operation requests on a target volume through a plurality of paths, a server receives the plurality of operation requests through the plurality of paths, where each of the plurality of operation requests may include a read request and / or a write request; based on the received multiple operation requests, the server applies for a shared lock for each operation request, so that the client executes the operation request through the shared lock. Namely, the server applies for the shared lock for the process corresponding to each operation request, so that concurrent read-write is realized through the shared lock, and the equipment performance is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] Ceph is a reliable, automatic rebalancing, and automatic recovery distributed storage system. According to the scene division, Ceph can be divided into three major blocks, namely object storage, block storage and file system storage. Among them, block storage (RADOS BlockDevice, RBD) is the most stable and commonly used storage type, and RBD devices can be mounted like disks. RBD block devices have features such as snapshots, multiple copies, cloning, and consistency, and data is stored in multiple object storage devices (object storage daemons, OSDs) in the Ceph cluster in a striped manner. [0003] The Internet Small Computer System Interface (ISCSI) is based on the TCP / IP protocol and is used to establish and manage the interconnection between IP storage devices, hosts and clients. The iSCSI proto...
