moving a 10G file without copying!
« on: February 22, 2009, 01:02:41 AM »

I want to move a file from one directory to another on my NAS drive.  When I try to do this, the 10G file is copied from the nas drive through my computer back to the nas drive.  I simply want to move the file from //dns323/volume1/foldera to //dns323/volume2/folderb.  Is there a way to do this without having to copy files through my computer?
Thanks,
Gary

ah i figured out the fastest way to do this move.  I had to telnet into the box (had to install funplug) and mv (moved) it from one place to another...

Without the need to know the Telnet command, and the need to install a program on you're computer, you can do these step :
1 - use the "Download" menu to FTP from one drive to the other
2 - Delete the file after transfer (manually from you're GUI).

I might be misunderstanding what you're saying, but what you're suggestion will still be slow since you have to ftp 10G of info right? Or will the ftp server be smart enough to know you're really doing a mv on a local machine? I think you'll still be copying info vs moving it which is just a change in the directory info on where the file lives, correct me if I am wrong.

Well either way, the DNS-323 has to move 10GB worth of data from drive 1 to drive 2. You're really dealing with the overhead difference between "mv" doing the move and ftp doing the move.

If you are moving the file to the same volume, but just a different directory, even SAMBA should be able to just change the directory info.

As long as it's on the same drive there's no problem. I moved a folder containing 114 GB on my raid1 dns-323 to another folder, and it was done in two seconds. So I don't understand whay you say it goes through your pc.

Your moving from 1 drive Volume_1 to the second Drive Volume_2 aren't you? This is not just a change in the directory info.

I think what Banshee meant is to use the Downloads utility to transfer the files from one volume to the other.
Moving files from one volume to the other is a major pain since the data does pass through the pc which acts as a bottleneck.

An easy workaround is to just go into Schedule Downloads and create a download job that moves the files.  Just schedule it for a few minutes ahead and hit the Download Now button.  The files transfer MUCH faster since they're not travelling through the pc.

Hope that helps

In all seriousness - if you find your PC to be the bottleneck, you probably need a new PC - any PC of recent manufacture (anything with a Pentium IV processor and quite a few Pentium IIIs), is at least an order of magnitude faster than the DNS-323.

What makes the difference is that you eliminate the transfer through the DNS-323's network interface, across the LAN to the PC and back.

heh, I wasn't exactly trying to be technical there...all I was saying was that having to transfer to the pc and back causes a bottleneck that doesn't really need to be there...

Agreed.

But - that bottleneck is still internal to the DNS-323.
