Abstract

The invention discloses a distributed file system snapshot rollback metadata processing method, which includes the steps of receiving a rollback request of a client through a main thread; starting theasynchronous processing thread which is independent of the main thread, and rolling back the metadata through the asynchronous processing thread; in response to the corresponding client, sending therollback completed response information to the client. As can be seen, the process of rolling back the metadata in the present application is performed by an asynchronous processing thread independentof the main thread, in the process of rollback, the normal service will not be affected, the problem that a cluster cannot provide normal service due to metadata synchronization process in a conventional process of rollback is solved, service needs not to be suspended, and the user experience is improved. In addition, the present application also provides a distributed file system snapshot rollback metadata processing apparatus and device, and a computer-readable storage medium having the advantages of the above technology.

Description

technical field [0001] The present invention relates to the technical field of distributed files, in particular to a distributed file system snapshot rollback metadata processing method, device, equipment and computer-readable storage medium. Background technique [0002] A snapshot can be a copy or replication of a data representation. For the file system, the file system snapshot is an instant copy of the file system, which contains all the information of the file system at the time of snapshot generation, and is itself a complete and usable copy. For snapshots, data recovery is a very important function, and the data recovery time is an important indicator for quantifying snapshot performance. [0003] In the existing technology for implementing online snapshot rollback, it often has a great impact on normal business, which leads to the situation that the cluster cannot provide normal business. Contents of the invention [0004] The purpose of the present invention is...
