Abstract

Various embodiments of the present disclosure provide a method for presenting a storage cluster status, comprising: in response to a request for monitoring a first target node in a storage cluster, monitoring whether a configuration status of the first target node is changed; and in response to the configuration status of the first target node being changed, presenting changed configuration status information of the first target node to the user.

First claim

The invention claimed is:

1. A method of presenting a storage cluster status, comprising:
in response to a request for monitoring a first target node in a storage cluster, monitoring whether a configuration status of the first target node is changed at least in part by monitoring whether the first target node fails;
in response to the configuration status of the first target node being changed, presenting changed configuration status information of the first target node to the user; and
in response to failure of the first target node:
presenting failure status information of the first node to the user, and
failing over an active system where the first target node is located to a backup system.

2. The method according to claim 1 , further comprising:
in response to the configuration status of the first target node being changed, storing the changed configuration status information of the first target node in a configuration database.

3. The method according to claim 2 , wherein the configuration database is configured to store the configuration status information of all nodes in the storage cluster.

4. The method according to claim 3 , wherein the configuration status information stored in the configuration database is organized in a tree-like structure.

5. The method according to claim 1 , further comprising:
in response to a request for querying a second target node in the storage cluster, returning configuration status information of the second target node; and
presenting the configuration status information of the second target node to the user.

6. An apparatus for presenting a storage cluster status, comprising:
a processor coupled to a computer readable memory;
a monitoring unit configured to, in response to a request for monitoring a first target node in a storage cluster, monitor whether a configuration status of the first target node is changed at least in part by monitoring whether the first target node fails;
a displaying unit configured to:

in response to the configuration status of the first target node being changed, present changed configuration status information of the first target node to the user, and
in response to failure of the first target node, present failure status information of the first node to the user; and
a failover unit configured to, in response to failure of the first target node, fail over an active system where the first target node is located to a backup system.

7. The apparatus according to claim 6 , further comprising:
a configuration database configured to, in response to the configuration status of the first target node being changed, store the changed configuration status information of the first target node.

8. The apparatus according to claim 7 , wherein the configuration database is configured to store the configuration status information of all nodes in the storage cluster.

9. The apparatus according to claim 8 , wherein the configuration status information stored in the configuration database is organized in a tree-like structure.

10. The apparatus according to claim 6 , further comprising:
a query unit configured to in response to a request for querying a second target node in the storage cluster, return configuration status information of the second target node; and
the displaying unit is further configured to present the configuration status information of the second target node to the user.

11. A computer program product for presenting a storage cluster status, the computer program product comprising:
a non-transitory computer readable medium encoded with computer-executable code, wherein the code is configured to enable the execution of:
in response to a request for monitoring a first target node in a storage cluster, monitoring whether a configuration status of the first target node is changed at least in part by monitoring whether the first target node fails;
in response to the configuration status of the first target node being changed, presenting changed configuration status information of the first target node to the user; and
in response to failure of the first target node:
presenting failure status information of the first node to the user, and
failing over an active system where the first target node is located to a backup system.

12. The computer program product according to claim 11 , wherein the code is further configured to enable the execution of:
in response to the configuration status of the first target node being changed, storing the changed configuration status information of the first target node in a configuration database.

13. The computer program product according to claim 12 , wherein the configuration database is configured to store the configuration status information of all nodes in the storage cluster.

14. The computer program product according to claim 13 , wherein the configuration status information stored in the configuration database is organized in a tree-like structure.

15. The computer program product according to claim 11 , wherein the code is further configured to enable the execution of:
in response to a request for querying a second target node in the storage cluster, returning configuration status information of the second target node; and
presenting the configuration status information of the second target node to the user.

16. A method of presenting a storage cluster status, comprising:
in response to a request for monitoring a first target node in a storage cluster, monitoring whether a configuration status of the first target node is changed;
in response to the configuration status of the first target node being changed, presenting changed configuration status information of the first target node to the user;
wherein presenting changed information of the first target node to the user further includes transmitting a notify message from a monitoring apparatus to a client in response to the monitoring apparatus detecting the configuration status of the first node being changed; and
wherein detecting by the monitoring apparatus that the configuration status of the first node is changed is performed by the monitoring apparatus in response to a watch request from the client.
