Abstract

The invention provides a heartbeat connection establishing method and device. The method is applied to a monitor in a Ceph cluster and comprises the steps that according to OSD topological informationof the Ceph cluster, a plurality of heartbeat connecting rings composed of OSDs are constructed, and each OSD on each heartbeat connecting ring is selected from OSDs in different storage nodes in theCeph cluster; and the neighbor OSD of each OSD on each heartbeat connection ring is sent to each OSD, so that each OSD respectively establishes heartbeat connection with the neighbor OSD. According to the invention, the communication load of the OSD in the Ceph cluster can be greatly reduced.

Description

technical field [0001] The present application relates to the field of storage, in particular to a method and device for establishing a heartbeat connection. Background technique [0002] In order to maintain the stable and reliable operation of the distributed storage system (Ceph) cluster, in the Ceph cluster, each object storage device (Object Storage Device, OSD) in each storage node will be connected according to the heartbeat configured by itself. For example, configure 10 heartbeat connections, and randomly establish heartbeat connections with the configured number of other OSDs. The other OSDs here may be other OSDs in the storage node to which the OSD belongs, or OSDs in other storage nodes. [0003] During the operation of the Ceph cluster, the OSD will send heartbeat messages to other OSDs, and will also listen to the heartbeat messages sent by other OSDs. Once the heartbeat message from the OSD that has established a heartbeat connection with itself is not receiv...
