Started out with a single 1.5 TB drive containing all my data

I've now added another identical blank 1.5 TB drive

I would like to retain the data from the original disk and utilize the new disk to create a RAID 1 Array.

How do I do this? So far it either looks like it will format both, or gets stuck at 0% formatting the new drive.

Any suggestions?

I've tried following the FAQ  - http://forums.dlink.com/index.php?topic=41834.0 but it just gets stuck...

Am using Google Chrome on Windows 8

Thanks

Still not working and have tried using a different browser. It just sits at 0% when its supposed to be formatting the new drive. No one has come across this before?

Here is a solution posted by a D-Link engineer some time ago that applies to the DNS-320. I can't say whether this works on the DNS-320L (or current firmware version of the DNS-320 for that matter): http://forums.dlink.com/index.php?topic=41180.0

Thanks JavaLawyer.

Incidentally, I decided to leave it sat at the above screen for an hour or so and its now saying complete BUT under Hard Drive Configuration it states Volume_1 : RAID 1(Degraded)

Any ideas? Will take a read of the other thread in due course.

[JavaLawyer]

My own personal preference would be to let the DNS-320L format a RAID-1 array from scratch and then migrate the data from a backup. Call me paranoid, but when it comes to data integrity, I never trust upgrade paths for storage (regardless of the device/brand or reliability of the upgrade). I'd rather be safe than sorry.

Again, this is a personal preference that in no way relates to the effectiveness or reliability of the storage configuration upgrade paths supported by the ShareCenter series.

I don't have enough drives to do that, I've got a pair of 1.5TB units along with 1TB of data to go on them in RAID 1 Config. All my PCs have low capacity SSDs.

Are you saying this functionality just "doesn't work"? I left it overnight and selected the option to rebuild the array but it is still saying Volume_1 : RAID 1(Degraded). Not particularly impressed with D-Link...

[JavaLawyer]

I appreciate the fact that you don't have enough drives for data migration, but that also implies that you don't have a backup of your data. I should point out that RAID is not a substitute for a backup. Two standard volumes will provide better data integrity than a RAID-1 configuration:

• ShareCenter - RAID-1 is NOT a Backup
  
• DNS-320L - Data Backup vs. Redundancy
  

[J400uk]

Sorry but you're not helping, the simple fact remains the product isn't working as described in the manual and D-Link can't seem to answer why. Wouldn't have had to go through this nonsense if there had been a proper migration path from the old dns-320

[JavaLawyer]

One question I haven't asked yet. . . What firmware version are you using?

[J400uk]

Hi it's on 1.02b07, thanks

Hi,

I have a similar problem, you can check my post here: http://forums.dlink.com/index.php?topic=54377.0
I had a spare disk so I've rebuild the array from scratch and restored data from backup,
but if this is not an option for you you can try to swap disks once the RAID gets rebuild.

Many thanks for your reply, that is indeed exactly the same problem I'm currently encountering. Seems a shame D-Link are unable to produce a fix as it seems a waste to buy a third disk just to get this working.
