The Graveyard - Products No Longer Supported => D-Link Storage => DNS-323 => Topic started by: lozinthevilla on May 14, 2010, 03:36:51 PM

1. Like the plank that I am when I first got my dns323 I chose RAID1 for my disk configuration and felt all smug about it. One year on, one of the disks has failed, and I realize that RAID1 for me is pointless. I really should have used two volumes instead.
I have got a new disk but would like to take the opportunity to have two individual disk volumes and use one of the volumes to backup the other.
Is it possible to reconfigure my existing disk to an individual volume1 and add the new disk and create a new volume2 without formatting my existing disk in the dns unit?
2. Also the dns is telling that my existing disk has failed, but when I have checked it, I can't find any errors... weird. Is it telling my lies, or is this because my RAID1 is broken?
3. Can I also ask is it possible to have more than one funplug installed on a dns323? I have squeezecentre at the moment but would like to add more.
I also 'upgraded' (I use the term in its loosest sense) to 1.08 firmware.
Thanks in advance.

Sounds to me this is exactly why you need RAID1- to prevent data loss in case of disk failure.
Did you run the manufacturers diagnostic tool on the disk? Did you try reseating the disk?
If you really want to downgrade to two volumes you could try taking all disks out, putting your new disk in and formatting it as individual disks, reinsert your original disk that was part of your RAID1 array. Not sure if your second disk will have any extra information on it to confuse the NAS though as it was part of a RAID.
Personally, I'd backup the data and start from scrath with two formatted, separate drives. At least you have a copy then should something go wrong.
fun_plug in it's simplist form is just a single shell script file executed when the NAS starts. It's not supported by Dlink. Not really sure what you mean about multiple ones. If you mean FFP and something else, that depends on your Linux skills. You will need to ask those questions at the other forums.

Thanks for the reply.

For me, its really confusing which strategy to follow. You're right RAID1 will help me against a disk failure. I have read other persuasive arguments for individual disk volumes and performing nightly backups.
I shall check out with the disk manufacturers tools.
Thanks again!

You might want to consider dumping the data to USB hard disks or SATA enclosure. Then you have RAID to prevent data loss in case of drive failure, and backups to refer back to.
Each month I backup the data to one of two SATA drives and rotate them each time.
-
I have two SATA disks connected to this main system, and three NAS units. They all have the same data on them, separated by the backup intervals. I do a cascade so that I have time to recognize a problem before data might be overwritten, and the USB disks are manually updated. I also have some NDAS drives in a remote part of the basement that get updated manually from time to time. If I ever lose all the copies of my important data, it's because I got really stupid! :D

I admire your paranoia gunrunnerjohn! I thought I was paranoid.
-
Anyone that uses Raid1+ is a bit paranoid at certain level, but apparently we've got a winner right here ;D
-
Anyone who has lost data (including me) knows why the paranoia exists :)
-
On at least one occasion, I've dipped into the second level of my backups.
Just because I'm paranoid, it doesn't mean they're not out to get me! :P
-
Thanks for your input everyone!
I have on order some more hard disks so I can make backups.
So I'm going to keep my RAID1 and have a usb enclosure for a hard disk backup.
What's the best way to do this please?
Can I connect the usb enclosure the DNS directly or do I have to connect via a PC?
What methods do you use?
Thanks in advance.

You will have to connect the USB disk to your computer, the USB port on the DNS-323 doesn't support disks at this time.

Ah! Does that mean that some time on the future it might? ???

That's a question for D-Link, but I wouldn't count on any significant speed if it does... :)
-
I have my USB enclosure connected directly to the USB port of the NAS. It's possible to do what you want using fun_plug. Unfortunately we're not supposed to talk about it on here as it's not supported by Dlink... If you fancy playing around with Linux, try googling dns 323 external disk - it might help you.
-
Gotchya! ;) Thanks for that!
-
As you will see elsewhere in this forum - I followed you advice and did a backup before my dns or I nuked my disks.
Thanks for the advice - I'm now a convert to external disk backups! :)
