Problems solved by technology
[0005] When the scale of the distributed storage system is relatively large, it is more complicated to adopt zookeeper management; in addition, when there is a problem with the zookeeper system, it will cause the entire storage system to fail to obtain a lease, and then stop providing services to the outside world, affecting the normal operation of the system business

Embodiment Construction
[0032] The solution of the embodiment of the present invention is mainly as follows: when the route management server detects that the host is down, switch the system route to the read-only standby state; When reporting system routing information, modify the system routing information, set the standby machine as the master, and synchronize the modified system routing information by all access servers.
[0033] Such as figure 1 As shown, the first embodiment of the present invention proposes a routing method for a distributed storage system, including:
[0034] Step S101, when the routing management server detects that the host is down, switch the system routing to a read-only standby state;
[0035] The architecture of the distributed storage system involved in the method of this embodiment is as follows: figure 2 As shown, the distributed storage system includes: a routing (route) management server, a storage server, and several access servers, wherein:
[0036] Access se...

The invention relates to a route method and server of a distributed storage system, and a distributed storage system. The method comprises the following steps: when a route management server monitors that a host breaks down, switching a system router to be at a read-only backup machine state; receiving report information after an access server successfully synchronizes system route information of the read-only backup machine state; and when the report information after the access server successfully synchronizes the system route information of the read-only backup machine state, modifying the system route information, arranging a backup machine to be the host, and all access servers synchronizing the modified system route information. According to the invention, under the condition that the host breaks down, automatic switching between the host and the backup machine is realized, data consistency during host-backup switching of the distributed storage system is ensured, and the system performance is improved.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a routing method for a distributed storage system, a routing management server and a system. Background technique [0002] The distributed storage system is configured with a host and a backup. The host is the node that actually provides external services; the backup is the corresponding backup node deployed for the host. When the host goes down, the backup is automatically upgraded to the host , to provide external services to improve data security. [0003] With the gradual increase in the scale of distributed storage systems, node downtime has become a relatively common phenomenon. In the case of host downtime, how to upgrade the backup machine to the main machine and provide external services in the shortest possible time. At this time It requires automatic master-standby switching technology, which does not require manual intervention, and ensures no mistaken switching an...
