I got two folders mounted via smb. One is G drive and the other is H drive. Both share is from the same nas box.

When I move a folder from H drive to G drive, some folders moves instantly and some will do a move across the network. Say I move a 5GB folder, it will move instantly. Then I try another 5GB folder, it will do a transfer so will go from nas -> my pc -> back to nas again. It's driving me nuts, any idea what could be causing it?

How is your NAS set up? If it has multiple physical drives, your problem likely is that sometimes the data that you are moving is on the same drive, and sometimes it is not. –  user130039 Nov 11 '12 at 16:07
    
It has got 4 drives and it is using raid5 with only 1 volume. I sort of fixed it. I mounted the drives in windows using root instead of normal accounts. But the normal accounts do have full rwx access to the files. –  lbanz Nov 11 '12 at 19:39
    
If there is only one volume, where are your two shares coming from? Are they subdirectories on the same volume? –  user130039 Nov 11 '12 at 20:08
    
Yes, that is right. One of the share is /c/all and the other is /c/home I looked at the file ownership and group. They were different at first and I made them the same but no luck. –  lbanz Nov 12 '12 at 0:09
    
I should clarify this. In windows they are mounted as \\nas\all and \\nas\home but on the linux server the real path is \\nas\c\all and \\nas\c\home\user1. I found that if I disconnect the share and mount it as \\nas\c using root account then the files doesn't move across the network. But using normal accounts, some files will move across the network and some doesn't. –  lbanz Nov 12 '12 at 0:32
