Hi I have a question about configuration of the MooseFS-Filesystem. I got the following infrastructure... 4 Chunkservers 1 Master 2 clients Now I want 2 Filesystems (FS1 and FS2) In FS1 is Server 1+2 and in FS2 is Server 3+4. Both should be handled by the one Masterserver and the clients should connect to both Filesystems... Now I don't know if this is possible... or do I need one Master for a Filesystem? It would be great if someone can help me :) Best regards, Ch.Raible -- Vorstand/Board of Management: Dr. Bernd Finkbeiner, Dr. Roland Niemeier, Dr. Arno Steitz, Dr. Ingrid Zech Vorsitzender des Aufsichtsrats/ Chairman of the Supervisory Board: Philippe Miltin Sitz/Registered Office: Tuebingen Registergericht/Registration Court: Stuttgart Registernummer/Commercial Register No.: HRB 382196 |

Hi, I have effectively 13 filesystems on one mfsmaster, but only one underlying "filesystem". The thing to do is to just have your clients mount subdirectories under the moosefs root directory, so the moosefs root directory looks like this: /stuff/<files> /morestuff/<files> and then on the client you mount like this: mfsmount <mountpoint> -S stuff # mounts the /stuff directory to the mountpoint instead of the whole moosefs mount I use this to partition out data for different environments and different types of data, so I have: /users /prod/media /qa/media etc. On Wed, May 18, 2011 at 2:02 AM, Christoph Raible < c.r...@sc...> wrote: > Hi > > I have a question about configuration of the MooseFS-Filesystem.

But I'm looking for a solution with 2 FS... Because the 4 Server are located on two different serverrooms... and the bandwith between them is not very good (100 MBit). And I don't want that Server 1+2 synchronize Data to Server 3+4... Thats why I want to have two differen Filesystems. Someone any idea / information?

Sounds to me like you want 2 mfs masters. MooseFS is not great over slow links, and if you have 2 masters then you have better distributed load anyway. Your clients just need to specify what host they are connecting to when they mount the FS -Thomas S Hatch |
