Abstract

A computer-implemented method according to one embodiment includes receiving, via an interface of a clustered file system, callback registration information from an external service, identifying a plurality of parameters associated with the callback registration information, constructing a service registration within the clustered file system, based on the plurality of parameters, identifying the service registration in response to an occurrence of one or more events, and performing one or more callbacks, according to the service registration.

Claims

1. A computer-implemented method, comprising:

receiving, via an interface of a clustered file system, callback registration information from an external service;

identifying a plurality of parameters associated with the callback registration information;

constructing a service registration within the clustered file system, based on the plurality of parameters;

identifying the service registration in response to an occurrence of one or more events; and

performing one or more callbacks, according to the service registration.

2. The computer-implemented method of claim 1, wherein the plurality of parameters include a service specific function to be executed.

3. The computer-implemented method of claim 1, wherein the plurality of parameters include a predetermined transition phase that triggers an execution of a service specific function.

4. The computer-implemented method of claim 1, wherein the plurality of parameters include an order in which a service specific function and a plurality of additional functions are to be executed.

5. The computer-implemented method of claim 1, wherein the plurality of parameters include a synchronous or asynchronous attribute.

6. The computer-implemented method of claim 1, wherein the plurality of parameters include one or more error handling attributes.

7. The computer-implemented method of claim 1, wherein the external service includes a Server Message Block (SMB) service.

8. The computer-implemented method of claim 1, wherein the external service includes an OpenStack service.

9. The computer-implemented method of claim 1, wherein the service registration is utilized by the clustered file system to determine when a transition phase has occurred, and to identify the external service or additional external services, where the clustered file system sends a callback to the external service or additional external services in response to the transition phase.

10. The computer-implemented method of claim 1, wherein a plurality of callbacks are performed in an order determined using order functions specified by the external service and additional external services during a registration.

11. The computer-implemented method of claim 1, wherein the one or more events include a failure of a node within the clustered file system.

12. The computer-implemented method of claim 1, wherein the one or more events include a recovery of a failed node within the clustered file system.

13. A computer program product for extending clustered file system functionality, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:

receiving, utilizing the processor via an interface of a clustered file system, callback registration information from an external service;

identifying, utilizing the processor, a plurality of parameters associated with the callback registration information;

constructing, utilizing the processor, a service registration within the clustered file system, based on the plurality of parameters;

identifying, utilizing the processor, the service registration in response to an occurrence of one or more events; and

performing, utilizing the processor, one or more callbacks, according to the service registration.

14. The computer program product of claim 13, wherein the plurality of parameters include a service specific function to be executed.

15. The computer program product of claim 13, wherein the plurality of parameters include a predetermined transition phase that triggers an execution of a service specific function.

16. The computer program product of claim 13, wherein the plurality of parameters include an order in which a service specific function and a plurality of additional functions are to be executed.

17. The computer program product of claim 13, wherein the plurality of parameters include a synchronous or asynchronous attribute.

18. The computer program product of claim 13, wherein the plurality of parameters include one or more error handling attributes.

19. The computer program product of claim 13, wherein the external service includes a Server Message Block (SMB) service.

20. A system, comprising:

a processor; and

logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to;

receive, via an interface of a clustered file system, callback registration information from an external service;

identify a plurality of parameters associated with the callback registration information;

construct a service registration within the clustered file system, based on the plurality of parameters;

identify the service registration in response to an occurrence of one or more events; and

perform one or more callbacks, according to the service registration.
