Abstract

Provided are a virtualization based high availability cluster system and a method for managing failures in a virtualization based high availability cluster system. The high availability cluster system includes a plurality of virtual nodes, and a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node. One of the virtual nodes not included in a first physical node among the plurality of the physical nodes takes over resources related to a service if a failure is generated in one of virtual nodes included in the first physical node

Claims

1. A high availability cluster system comprising:

a plurality of virtual nodes; and

a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node,

wherein one of the virtual nodes not included in a first physical node among the plurality of the physical nodes takes over resources related to a service if a failure is generated in one of virtual nodes included in the first physical node

2. The system of claim 1, wherein each of the virtual nodes includes a high availability manager for generating a message that informs all of the virtual nodes that a failure is not generated in a corresponding virtual node and transmitting the generated message to virtual nodes in the same physical node.

3. A method for managing failure in a high availability cluster system comprising the steps of:

generating a failure in a first virtual node in a first physical node;

selecting one of a plurality of virtual nodes operated in a second physical node as a node for taking over resources related to a service through a failover process; and

taking over resources related to the service through the selected virtual node.

4. The method of claim 3, further comprising the step of:

at a plurality of virtual nodes operated in a physical node except the first physical node, recognizing that failures are generated in the first virtual node.

5. The method of claim 3, further comprising the step of:

at one of virtual nodes except the first virtual node among a plurality of virtual nodes included in physical nodes except the second physical node, taking over resources related to the service if a failure is generated in the selected virtual node
