rsync file size issue?

[pratapsingh]

Hello,

I am trying to rsync my data from one server to another server but I notice that the file on the new server using more space than old server. I transferred data using rsync -cz option .

Now the disk space usage on the old server and new server are as follows : Both server contains the same data not even a single file is different. Settings and file system are also same. Rsync version on both the server are also same it is 3.0.6.
old server
/dev/sda1 1T 547G /home
new server
/dev/sdb1 2T 648G /home
I tried the following command also to transfer the data :
rsync --delete -ae ssh

What could be the reason? How can I figure out what I have done wrong? It seems that the rsync is having some issue and not reliable to transfer large data.

Any suggestion in this regard will be appreciated .

Thanks.

Hello
Did anyone face the same issue before? I want to fix it or it is not possible. It's a bug with linux.
I need to know the reason. It is driving me crazy.
