Problems solved by technology

The user data to be written into the storage space is first sent to the storage node after forming the user data object, and the storage node calculates the HASH value of the user data object identifier, and then uses the calculated HASH value to address the Placement Group (PG) The modulus of the number of user data objects can be determined to determine which PG the user data object needs to be written to. Although this kind of user data object writing rule can guarantee the balance of data distribution to a certain extent, it may also cause the user data to be written to Unhealthy PG problems affect business continuity, and storage nodes cannot flexibly decide where to write user data objects

Abstract

The invention provides a data object storage method, a data object storage device and a storage medium, which are used for solving the technical problems of data balance and service continuity. According to the method, a health PG list is obtained from a monitoring node through an ROW module, a received user data object is converted into an ROW object, a mapping PG used for storing the ROW objectis selected from the health PG list through a preset data equilibrium distribution algorithm, an ROW object identifier is allocated to the ROW object, and the ROW object identifier comprises an ROW module identifier, an identifier of the mapping PG and a serial number; the ROW object is then written to the OSD in the mapped PG. According to the invention, the balanced storage of the ROW object canbe realized, and the service continuity is improved.

Description

technical field [0001] The present disclosure relates to the technical field of storage clusters, and in particular to a data object storage method, device and storage medium. Background technique [0002] A Ceph storage cluster includes multiple storage nodes, and one or more object storage devices (Object Storage Device, OSD) are hung under each storage node. The user data to be written into the storage space is first sent to the storage node after forming the user data object, and the storage node calculates the HASH value of the user data object identifier, and then uses the calculated HASH value to address the Placement Group (PG) The modulus of the number of user data objects can be determined to determine which PG the user data object needs to be written to. Although this kind of user data object writing rule can guarantee the balance of data distribution to a certain extent, it may also cause the user data to be written to Unhealthy PG problems affect business conti...
