Method for monitoring multi-machine distributed replicated block device and equipment

Abstract

The invention discloses a method for monitoring a multi-machine distributed replicated block device and equipment and aims to achieve a purpose of timely finding out malfunction of a host node in a distributed system. Firstly, a storage node of a node type is predefined in the distributed system, and a current node type status of the storage node is acquired through access to a client-side system status file, wherein the node type comprises the host node and a standby node. Secondly, when the predefined node type is the host node and the acquired current node type status is the standby node or the predefined node type is the standby node and the acquired current node type status is the host node, faulty information of the host node is returned.

Description

technical field

[0001] The invention relates to the field of distributed storage, in particular to a method and device for monitoring multi-machine distributed replication block devices. Background technique

[0002] With the widespread application of distributed storage technology, in the distributed environment with large data volume and large access volume, the data security and system stability of the distributed system are more and more concerned by users.

[0003] The Linux-based software component, distributed replication block device, can solve the security problem of data storage in a distributed environment to a certain extent. It is composed of kernel modules and related programs, and promotes the replacement of shared storage systems through network mirroring. That is to say: when data is written to the file system on the local DRBD device, the data will be sent to another host in the network at the same time, and recorded in a file system in exactly the same for...
