Migration from older to new ReadyNAS

You cannot just insert your existing drives from your NV+ to the RN314. Do you have a back up of all the data stored in it?

Kindly check this link: http://kb.netgear.com/app/answers/detai ... os6-nas%3F

You will need to contact Netgear Support for assistance regarding your concern :)

Backup is there for most of the data, so I am not completely out of luck.

I have R-Studio at hand to try a recovery run over the disks; as I understand R-Studio requires detailed knowledge of several low-level RAID layout parameters like block size, etc. I did have an X-Raid setup with three hard disks; are these parameters known by anyone?

You could contact support if you have purchased the 314 to enquire about support attempting to help you recover your data. There is a procedure that can be used. It is important not to insert the disks into the new NAS until prompted to by support.

Hi Guys!
I have similar problem with my NV+ (RND4000), and as far as I know the 4 pcs of HDDs are not damaged, but the PSU killed my mainboard too. :(
The question is... if my friend has similar RND4000, but maybe different Firmware/RADiator, can I put my 4 HDDs into his RND4000 for a backup? Will it work?
I really hope it will not kill all of my datas, family photos and videos, documents and official writs. :(

Please tell me, can I hope the success? :)
Thank you so much for your kind help and informations!

Yes you can, just put the drives on the same order as what you have on your old chassis. Do you remember the raidiator version you are using on your old NAS?

Here's the best practice when migrating disks:

First,make sure they are both v1 units . See http://www.rnasguide.com/2012/01/09/how ... -or-nv-v2/

If you have a spare disk (the one that is not from your array),insert it on the new nas and check the firmware. If the FW is older than what you have on the old NAS, you will need to update it.

After verifying the firmware update was successful, power down, remove the spare disk, migrate the disks across (keeping the order the same) and if it boots up fine, recalibrate the fan under Status > Health in Frontview.

You are really kind Nhellie for the quick reply! :)
Sadly I do not remember my NAS Firmare/RAIDiator version :( And can't check it, 'coz it's dead. :(
Of course I noted the order of disks, put some seals on HDDs.
And both v1 versions, I bought it in 2009 and 2010.
What do you think, do I risk the data integrity just simply put the disks into NAS, even I don't know the versions?

If the firmware stored in the flash memory is different from what is on the disks, then the NAS will install the flash onto the drives. This will happen even if the flash is older (that is, it will attempt to downgrade in that case).

If you don't know that the firmware is on the disks, then it is safest to upgrade the firmware on the NAS to the current version before you begin. That's because upgrading is generally always safe, but downgrading to very old firmware might not be. Of course your friend has to agree with the update.

You are right Stephen, I don't want to risk the friends' datas with upgrading his firmware.
But this is what I found on the link of Nhellie:
"» What file system does ReadyNAS use? Can I read a disk from ReadyNAS on other machines?
The ReadyNAS uses Linux Ext2/Ext3 file system. A typical Linux distro can mount and access the data from the disks."

Based on this information I can ask a Linux expert ( I am not a Linux expert :D ) lets put the disks into a PC with an installed Linux and try to access all of the data. Right?
It should work, right?

Check the current FW on the NAS first, if it is already updated then all you have to do is insert your drives. I'd mount the drives on another device if it is my only option.

It's not that simple, you also need to mount the RAID volume. There are instructions here: viewtopic.php?t=68586&p=381183#p381183 dbott has a guide on his own server, but that is down at the moment.

If the firmware on your friend's system is reasonably new, there shouldn't be an issue (though there always is some risk, it would be slight).

If its older than 4.1.8, let us know what he is running, and also the disk model numbers.
