[Moosefs-users] seeking code segment for mfs(about making copies)

[崔. <cui...@si...>]

Hello!
 I'm a student of China. Now I'm studying distributing file system, my lib use the MFS as a sample to study.
 I know MFS is a fault tolerant file system, I want to know how MFS build copies on chunkservers.(just as a question of "make a copy just after a write action or wait a free time to make copies.")
 I have reading the code try to find out where the code about "making copies" but I can't find it out. If you can help me or tell me the localtion of that code segment, I'm really thankful.
 (My MFS edition is 1.6.11)
 Thanks!
