ReadyNas NV+ Disk Failure upgrade
Hi,
I've got several ReadyNas NV+ and after many years of faithful service a Seagate Barracuda 750Gb disk has failed.
Can I replace it with a Hitachi Ultrastar a7k2000 2Tb and once it is synced in then replace each of the other drives in turn so that I move all the disks up to 2tb?
As well as this can I mix drives during the process and will I get all the space available at the end of the process?

- That mostly depends on the version of the firmware you're currently running on the ReadyNAS. If it's a 4.x version your plan should work out fine. It wouldn't be a bad idea to make a backup of your data on an USB attached 2TB drive first, however ;)
-Stefan - Help: Having replaced the drive I have been caught out by the 512b/4Kb issue. The drives have gone in OK and when I look in the https://nas/admin -> share listing the shares appear to be there with the correct amount of disk used. The volume has not resized from the original 1917Mb and fails to do so each time it is rebooted. Also if I go to https://nas/shares/ it says "No shares currently accessible." This is consistent with the problems of the 512b/4Kb issue. I have a backup of nearly everything that was on the NAS so I am not in desparate trouble here but I would like to get some additional files off.
So to my question: Is there a way to attach another drive say via the USB and use a unix type 'dd' command or something similar to copy off the data onto a readable drive so that I can check for any extra files? I can then re-initialise the whole device properly and copy the data back. - [quote="datamgmt"]Help: Also if I go to https://nas/shares/ it says "No shares currently accessible."

That is not the best way to access the shares. I have an NV+ (4x1TB Seagates, RAIDiator 4.1.7) and that is not the best way to access the shares, If I try it I can only get to the media share and it is empty. (Actually empty) If you are using Windows, in Computer or Windows Explorer, the NAS should show up in the network devices under the Network heading, and then you be able to access the shares that way.
Hindsight is always 20/20, but it is always best to make sure you have a current and complete backup of the system before making any major changes to it. This includes drive upgrades as well as firmware update. (Murphy's Law - Whatever can go wrong will go wrong) If you are having the 512b/4Kb issue, then it means you have an older NV+ that originally shipped with RAIDiator 3.x and while you have upgraded to 4.x, you have not done a factory default.
If you can't get access to the files, you can try opening an online case with tech support and see if they can do anything for you.
