Hi all

I have an term project for a distributed file system.My problem is about fam.I give an example for my problem.

if some system user changed any file which has a high capacity like 100 mb.I must copy this file to the other mirrors from the network because fam's software "fileschanged" don t give the changed block number of file.It only reports the file name like "/home/user/file.txt is changed". so i cant transfer the altered blocks.
I know "This is an optimization problem" if anybody solved before, can he give any suggestion ?

thanks
