Abstract

The embodiment of the invention provides a storage method and a distributed storage system. The problem of conflict between read operation and write operation and conflict between write operation and write operation caused by an existing storage mode is solved. The storage method is applied to the distributed storage system, the distributed storage system comprises at least two storage control nodes and one storage pool shared by at least two storage control nodes, and the storage pool comprises at least two storage units. When data is written into the storage pool by any one storage control node, the method comprises the steps that whether a repeated storage unit with data contents same as current written-in data exists in the storage pool or not is judged; if a judgment result is no, a leisure storage unit is allocated from the storage pool, and the current written-in data is written into the leisure storage unit.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a storage method and a distributed storage system. Background technique [0002] With the increasing scale of computer applications, the demand for storage space is also increasing. Correspondingly, it has become a mainstream now to integrate storage resources (for example, storage media such as disk groups) of multiple devices as a storage pool to provide storage services. However, in a distributed storage system including multiple storage control nodes, although multiple storage control nodes simultaneously perform read operations on the same storage unit in the storage pool without conflicting with each other, when multiple storage control nodes simultaneously Conflicts may occur when a write operation is performed on the same storage unit, or conflicts may also occur when two storage control nodes simultaneously perform read operations and write operations on the same s...
