DSM-G600, DNS-3xx and NSA-220 Hack Forum

Do not attemp to start an array with 1 500GB and 1 1TB drive.  A few things can / will happen.  First, the DNS occasionally will format the incorrect drive (the reason I do all my partitioning and formatting manually).  Assuming this works, the maximum array that can be set-up is 500 GB because it is the smallest drive.  When you try to put in the second 1 TB drive, you risk the incorrect format again, and you will still only have a 500 GB array (since that is what was set-up already).

Here is your easiest solution.  Remove both 500 GB drive from your unit.  Put 1 of them in a USB enclosure.  Put both 1 TB drives in the unit and set up the RAID 1.  Plug your USB enclosure into the USB port on the DNS and copy the data onto Volume 1.  This, of course assumes you know a little bit about linux (or want to learn) and you setup fun_plug to (probably ffp) for USB disk access.  All the info you need is on the wiki.

A slightly more complecated, but more fun (and in my opinion safer if you know what you are doing) is to set them up manually.  This would involve setting up the 1TB drive individually, taking 1 out and replacing it with 1 of the 500 GB drives, copying the data, putting back in the 1TB drive, then manually building the RAID 1 array.  You can learn a ton doing it this way.  I have also written some scripts to make this go very easily and semi-automatically.  They were not written specifically for upgrading to larger drives, but could easily be modified for that purpose.  They actually were written to upgrade the arrays built under F/W 1.03 to the standard for 1.04 and 1.05.  I made them modular so I can move things around easily.  Let me know if you are interested.

Yes they can.  The issue you will have with plugging the drive into your PC via USB is that it is EXT2 format and you will need yo run another software to get it to work.  I have played with it a bit, but have not gotten it to work on my Vista machine.  I would do it natively on the DNS.

Here are the crash course instructions:

1) shutdown and remove your drives
2) insert the new drives
3) boot up and get the new raid 1 running
4) install ffp
5) copy the usb-storage.ko file to the DNS Volume_1 (file attached)
6) telnet in and run

insmod /mnt/HD_a2/usb-storage.ko

7) plug in the USB drive (with one of your 500 GB drives in it) and wait 30 seconds
8)run

mkdir /mnt/USB
mount /dev/sdc2 /mnt/USB
cp -dprf /mnt/USB/* /mnt/HD_a2/

9) wait for the copy to finish.  It will probably take several hours. Run

sync

10) unmount the USB drive, then you can unplug it.
