Abstract

The present invention provides a storage resource grouping method, system, terminal and storage medium, including: setting the number of nodes in a group; after receiving a group creation request sent by a client, querying current node usage information in a default storage pool; The usage information is used to judge whether there is an idle node that meets the number of nodes in the group: if so, select the idle node with the number of nodes in the group to establish a group, and output the group information as the target node group information; if not, query The existing node group with the fewest connected clients among the existing node groups, and the queried existing node group information is output as the target node group information. The invention saves the resources of the cluster system, reduces the redundant paths exported by the block device, and reduces the pressure on the client.

Description

technical field [0001] The present invention relates to the technical field of storage resource allocation, in particular to a storage resource grouping method, system, terminal and storage medium. Background technique [0002] iSCSI mainly uses the TCP / IP technology to make the storage device (RBD) end through the iSCSI target (iSCSI target) function to make the server end that can provide disks, and then through the iSCSI initiator (iSCSI initialization user) function to do To be able to mount the client using the iSCSI target, so that the disk application can be performed through the iSCSI protocol. [0003] The client can establish a connection with tgt through the above methods to access the underlying librbd (Librbd is the library that Ceph provides block storage), and realize the operation of block storage. Multiple block devices can be mapped on one target, and multiple block devices can be created on one tgt at the same time. target, the client can connect to one o...
