Problems solved by technology
[0003] However, when the above-mentioned storage device calculates the storage location of a data, deviations are likely to occur, for example: the storage location of a data determined by calculation on the above-mentioned storage device is exactly at the storage location where the metadata is stored, and the data will overwrite the The metadata stored in the storage location, and then the metadata is misoperated, the above-mentioned storage device will inevitably have problems when reading the metadata, and even cause the storage system to crash
[0004] In the existing technology, there is a lack of protection for metadata. When storing data, the data is likely to overwrite the stored metadata, causing the storage device to fail to read the metadata correctly, and even causing the storage system to crash, reducing the reliability of the storage system. sex

The embodiment of the invention discloses a data storage method and device which are applied to storage equipment. The storage equipment comprises a metadata storage area, and the method comprises the steps of receiving a data storage request, determining a target storage position of data to be stored which is contained in the data storage request, judging whether or not the target storage position is in the metadata storage area, if the target storage position is in the metadata storage area, judging whether or not the data to be stored is metadata, if yes, storing the data to be stored to the target storage position on the condition that preset storage conditions are met, and if no, refusing to store the data to be stored to the target storage position. Data is stored by applying the data storage method and device, and the reliability of a storage system is improved.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a data storage method and device. Background technique [0002] For block storage-based storage systems, the importance of metadata in storage devices is self-evident. At present, in the storage system, in order to improve data storage efficiency, the real data and the metadata of the real data are often stored on the same storage device, for example: when storing a piece of data, first calculate the storage location of the data on the storage device , determine the storage location of the data, and store the data in the storage location. This allows efficient storage of data. [0003] However, when the above-mentioned storage device calculates the storage location of a data, deviations are likely to occur. For example, the storage location of a data determined by calculation on the above-mentioned storage device is exactly at the storage location where the metadata is stored, an...
