Re: [Moosefs-users] Local writing and rack awareness?

Hi Stas!

 

Ad. 1)

Yes. When one copy of a chunk is located on a computer from which comes
request to return all locations of the file (both at read and write) then
this locations is sent as first. In case of reading client chooses this
location as a preferred one, in case of writing the location would be at the
first place in a chain of connections.

 

Ad. 2)

No. It is on our roadmap but now we cannot tell when this functionality
would be implemented.

 

If you need to increase performance you can have a look here:

Subject: [Moosefs-users] Local writing and rack awareness?

 

Hi.

I have couple of questions I wanted to ask about MFS:

1) In case the MFS chunk-server writes data, does it recognizes this and
writes to itself first, and also reads from itself first, in order to
speed-up operations?

2) Also, does MFS support rack awareness, where it replicates the files
within same sub-net first, and only moves later to other sub-nets?

Regards.
