Abstract

The invention discloses a storage node isolation method and device. The method comprises the steps that storage node timeout convergence tables sent by multiple clients are acquired, and the timeout frequency, recorded by the clients, of each storage node when the clients sending the storage node timeout convergence tables access the multiple storage nodes within a preset duration is recorded in each storage node timeout convergence table; all storage nodes in the storage node timeout convergence table are counted to obtain a plurality of target storage nodes; according to the storage node timeout convergence table, timeout times of each storage node is counted in the target storage node; a first storage node is determined from the target storage nodes according to the timeout times of each storage node, and the first storage node is a fault node; and the first storage node is transferred to a storage node isolation pool. According to the invention, the technical problem of low storagenode isolation efficiency in related technologies is solved.

Description

technical field [0001] The present invention relates to the field of distributed storage, in particular to a storage node isolation method and device. Background technique [0002] In the process of distributed storage, the client needs to access the storage node through the metadata server. However, during the process of allocating storage nodes, there may be failures in the storage nodes. [0003] For the above method, in the prior art, by adding a network monitoring module to the client, the client needs to periodically send detection messages to the storage node, so as to detect whether the storage node is faulty. And when the storage node fails, isolate the storage node. [0004] However, if the above method is adopted, a large amount of client bandwidth needs to be wasted in order to realize fault detection and isolation of storage nodes. [0005] For the above problems, no effective solution has been proposed yet. Contents of the invention [0006] Embodiments o...
