Abstract

Briefly, embodiments of methods and/or systems of providing services in a distributed file system are disclosed. For one embodiment, as an example, a system may be capable of forming server-side mount tables comprising hierarchically organized namespaces. Server-side mount tables may be replicated or reproduced across services platforms, for example.

Claims

1. A method comprising:

forming one or more server-side mount tables for a namespace;

replicating said one or more server-side mount tables across a distributed system of platforms; and

performing no more than a single redirection responsive to a request for access to content hosted via said distributed system.

2. The method of claim 1, wherein said request for access to said content comprises a client-side request.

3. The method of claim 1, wherein said namespace comprises a hierarchy of content related parameters organized into a directory.

4. The method of claim 3, further comprising:

migrating one or more subdirectories within said namespace from a first location within said directory to a second location within said directory, said migrating being at least partially in response to load balancing of stored content related parameters among said platforms of said distributed system.

5. The method of claim 4, further comprising:

replicating said directory among said platforms across said distributed system responsive to said migrating.

6. The method of claim 3, further comprising:

detaching a subtree from a first location of said directory; and

attaching said detached subtree to a second location of said directory.

7. The method of claim 6, further comprising:

preserving platform identifiers of said stored parameters during said detaching and said attaching.

8. An article comprising:

a non-transitory storage medium comprising instructions stored thereon executable by a special purpose computing apparatus to;

generate one or more server-side mount tables for a namespace of a distributed system; and

perform no more than a single redirection responsive to a request for access to content hosted via said distributed system.

9. The article of claim 8, wherein said namespace to comprise a hierarchy of content related parameters organized into a directory.

10. The article of claim 9, wherein said instructions are further executable to:

migrate one or more subdirectories of said stored content related parameters from a first platform of said distributed system to a second platform of said distributed system, said migrating to be at least partially in response to load balancing among said platforms of said distributed system.

11. The article of claim 9, wherein said request for access to said content to comprise a client-side request.

12. The article of claim 9, wherein said instructions are further executable to:

replicate said one or more server-side mount tables among said platforms of said distributed system responsive to said migrating.

13. The article of claim 9, wherein said instructions are further executable to:

detach a subtree from a first location of said distributed system; and

attach said detached subtree to a second location of said distributed system.

14. The article of claim 13, wherein said instructions are further executable to:

preserve platform identifiers of said content related parameters during said detaching and said attaching.

15. A system comprising:

a distributed set of computing devices;

the computing devices of said distributed set to redirect a request for one or more content related parameters no more than a single time from a first platform of said distributed set to a second platform of said distributed set, to replicate a directory among a plurality of platforms in said set, and to load balance storage of said content related parameters among said plurality of platforms.

16. The system of claim 15, wherein said request to originate from a client computing device.

17. The system of claim 15, wherein said directory to comprise a hierarchically organized file structure.

18. The system of claim 15, wherein at least one of said computing devices to detach and reattach a subdirectory of said directory to load balance storage from a first platform of said plurality to a second platform of said plurality.

19. The system of claim 18, wherein said at least one of said computing devices to update said directory responsive to said load balance of storage.

20. The system of claim 19, wherein said at least one of said computing devices to replicate said updated directory across said plurality of platforms.
