Hello,
I currently have 2x250GB sata spare drives and I am considering buying a DNS-323 and implement RAID 1.
A year from now I plan to upgrade the HDs to something around 1TB , or whatever I can buy under $100.00 bucks a piece.
My question is:
When I upgrade the drives, can I pull 1 x 250GB out and replace with 1 TB, setup the RAID and wait for the disks to synchronize and then say a day later replace the 2nd hard drive ? Will I have 1TB at the end?
Thank you,
Indiana

No. You will have to manually configure the raid array in linux to do it. If you attempt what you suggest, the 1 TB drive you add will only form a 250 GB raid array (smaller of the 2 drives). When you put in the second 1 TB, it will sync to 250 GB (it will only see the 250 GB raid array on the first 1 TB drive). This is of course assuming you do not lose the data while swapping disks around. The unit does not like that.
It can, however, be done manually reletively easily. Or, get a cheap USB enclosure and it is even easier. With a USB enclosuer, you setup the raid 1 on the 1 TB drives normally and stick 1 of your 250 GB drives in the enclosure. Then using ffp and usbstorage.ko, you will be able to connect the USB drive to the unit and copy your data onto the new array. It is really easy to do.
