Title:
METHOD AND APPARATUS FOR SYNCHRONIZING SERVICE REQUEST OF STORAGE NODE
Document Type and Number:
WIPO Patent Application WO/2017/101016
Kind Code:
A1
Abstract:
The embodiments of the present invention relate to a method and apparatus for synchronizing a service request of a storage node. The method comprises: when a first storage node has a fault within t1 to t2 while executing a plurality of service requests, determining a set of service requests, which are recorded in a first log, and of which a starting execution moment is within (t1-2dt) to (t2+2dt), as a first service request set, and a set of service requests, which are recorded in a second log, and of which a starting execution moment is within (t1-dt) to (t2+dt), as a second service request set, wherein dt is the maximum time span for executing the service requests; and determining that a service request belonging to the second service request set but not belonging to the first service request set is a service request lost by the first storage node during the occurrence of the fault so as to facilitate the first storage node executing the lost service request. By means of the method and apparatus for synchronizing a service request of a storage node in the embodiments of the invention, a lost service request can be obtained accurately, and service requests of a normal storage node and a faulty storage node can be synchronized, so that the throughput of a storage system in executing the service requests is improved.
