[Moosefs-users] Fwd: I want to know the detail of write process

[洪志雄 <fis...@gm...>]

I was read source code of the MFS(ver1.6.15) these days. I have a question
about write process.

>From source code, I saw if  in the client if wanting  to write  data, It
would created a job in queue.   all job would be done with in
write_worker() (in  mfsmount/writedata.c).

>From the picture of  MooseFS Write Process( in moosefs index page), The
processes of 1, 2, 3, 4 were clearly in write_worker(), but process 5, 6
which synchronized the data  between chunk server  I couldn't find it  in
source code . Would please provide  some clues about this problem.

Thanks:)

Code responsible for communication between chunkservers is in "mfschunkserver/csserv.c" file, main functions are: "csserv_fwd*", "csserv_forward", "csserv_write_*".

 

If you need any further assistance please let us know.

 

 

Kind regards
