Embodiment Construction

[0059] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060] The present invention provides a data migration method based on nbd equipment. In the first embodiment of the data migration method based on nbd equipment in the present invention, refer to figure 1 , the data migration method based on the nbd device is applied to the Ceph client in the Ceph distributed system, the Ceph client includes a local disk, the Ceph distributed system also includes a Ceph cluster, and the data based on the nbd device Migration methods include:

[0061] Step S10, when detecting that the rbd-nbd process starts, obtain the target nbd device corresponding to the rbd-nbd process at the Ceph client;

[0062] Step S20, if it is detected that a read-write service processing request is performed based on the target nbd device, determine whether the target data requested by the read-write servi...

Abstract

The invention discloses a data migration method, device and equipment based on nbd equipment and a storage medium. The method comprises the following steps: when detecting that an rbd-nbd process is started, acquiring a target nbd device corresponding to the rbd-nbd process at Ceph client; if it is detected that a read-write service processing request is carried out based on the target nbd device,judging whether target data requested by the read-write service processing request is migrated to the Ceph cluster from the local disk or not; if the target data is not migrated to the Ceph cluster from the local disk, reading the target data from the local disk, and based on the rbd-nbd process, sending the target data to the Ceph cluster. By means of the data migration method and device, the technical problems that in the prior art, in the process of migrating data of a local disk to a distributed storage system, the efficiency is low, and the service continuity is affected are solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data migration method, device, device and storage medium based on nbd equipment. Background technique [0002] The Ceph distributed system includes the Ceph client and the Ceph cluster. The Ceph client includes the network block device (network block device). A block device, where the Ceph client can select a created nbd device locally and connect to the rbd device of the Ceph cluster through the preset nbd protocol. Specifically, the rbd device can be understood as a storage device in the Ceph cluster , it should be noted that in the Ceph distributed system, reading and writing on the Ceph client nbd device needs to be converted into reading and writing to the rbd device in the Ceph cluster. After the reading and writing of the rbd device in the Ceph cluster is completed, obtain the rbd device The read and write content of the Ceph client nbd device is returned to t...
