Abstract

The invention discloses a method, system and device for communication of Ceph kernel client and medium, and the method comprises the steps: building communication between the Ceph kernel client and a Ceph distributed storage based on an RoCE protocol, and building and initializing a sending completion queue and a receiving completion queue; in response to sending a message to the Ceph distributed storage and the type of the message being a non-blocking message, determining a first size of the to-be-sent data according to the message; calculating a second size of the data which can be sent this time according to the size of the current idle cache, and judging whether the second size is smaller than the first size or not; in response to the fact that the second size is smaller than the first size, obtaining a request sent to a sending completion queue, and releasing a cache corresponding to the request to update a current idle cache; and copying the data to be sent to the updated current idle cache, submitting a request to the sending completion queue to send the data to be sent, updating the first size based on the size of the copied data, and sending the data again until the first size is zero.

Description

technical field [0001] The present invention relates to the field of distributed file systems, and more specifically, refers to a method, system, computer equipment and readable medium for communicating with a Ceph kernel client. Background technique [0002] Ceph is a distributed file system with high performance, high reliability and high scalability. It can provide object storage, block device storage and file system storage. When Ceph provides file system storage, users can access it through the NAS client, and when the client is a linux system, it can also access it through the fs module in the linux kernel. Currently, there are kernel clients for linux systems to access the Ceph storage file system , the network implementation adopts the tcp / ip communication mode. The communication delay of the Ceph kernel client in the prior art is high, the CPU usage is high, and the communication efficiency is low. Contents of the invention [0003] In view of this, the purpose ...
