Hi,
I've 2 x 500Gb drives mirrored at the moment, i.e. 500Gb usable.
I'd like to upsize to 2 x 1Tb, but I want to kepe the data etc. on the DNS. Is there a method I can replace the 500Gb drives with 1Tb drives and still preserve my data?
Many thanks,
Nicko

There are a couple of options. One is to get an external USB drive for one of the 500GB drives, mount it, and copy the data to the fresh 1TB array. The other (and one I use) is to set up your 1 TB drives as individual drives, put in 1 of the 500 GB drives and copy the data over. Next, run my raid build script which will build the array for the 1 TB drives. No matter what, it involves copying the data.
Lastly, my favorite. Buy another DNS and keep both sets.

Thanks - what about all the shares etc.? Can I keep the DNS config, passwords etc.?
Cheers

Yes. Those are stored in flash.

Thanks for this - is there an "Idiots guide" to this process? ;-)
I just bought 2 x 1Tb Samsung Spinpoint drives - 32Mb cache, 7200rpm, about GBP 90 each. They run cool, too...
Thanks

No, not really. Do you have a USB drive that your disks will fit into? If you do, take out your disks, put in the new ones, set them up as raid1, then copy your data from the old ones into the DNS. This is by far the easiest and safest. If not, let me know and I'll get you the scripts.

Thanks for your help on this - I now have an external USB 2 hard drive box for the old drives.
Last question: What do I use to copy the contents of the old drive back to the new disks on the DNS? Is there some specific utility I should be using? Does the external USB drive plug into the USB port on the DNS?
Many thanks

Here is how I would do it:
1) set-up your new disks in the DNS (format, raid, the whole works)
2) Install ffp and support for USB disk drive (both on the wiki)
3) plug the USB disk into the DNS
4) Telnet in and mount the USB drive
5) copy all the data over (I would probably use cp -dprv)

If you don't want to deal with ffp, telnet, or USB support, you can always plug the external HDD into your computer and just copy to the DNS-323 over the network.

That will work for some of the files. Files that have certain permissions will not copy properly that way.
