How to copy data from the one harddrive to another within the same readynas?
Hi, I have a ReadyNas RND2D running firmware version 6.10.1 in X-Raid mode and I had only one 1TB drive inserted into it. Everything is working fine but my drive is almost full. So I purchased a new...
Ok, I looked at the Genie manual and there's a whole section on remote managment. It turns out that Remote Management does NOT need to be enabled on the router. Remote management with Genie uses a different mechanism. You need to create a remote management account and register your router. Follow the instructions in the manual to set it up. They look easy to follow.
Having said this, I would be a bit wary about using this. The use of a remote managment account implies that remote access is faciliated by a Netgear server. After the initial setup, it's unclear how much Netgear is involved whenever you log in remotely. Hopefully, your login session doesn't go through any Netgear servers. That would be a huge privacy concern. What would be preferred is that the act of registering your router for remote management merely opens a port on the router and Genie opens a direct connection to router. Unfortunately, you have to log into the remote management account in order to access your router, so that suggests that Netgear is still involved.
Unless Netgear is willing to share more details about how this works, I would stay away from this feature and stick with the basic, browser-based Remote Management available on the router.
My $0.02, of course.
Hi StephenB ,
Thank you for your reply.
I want to double check a few things before removing the old 1 TB.
At the moment, in my understanding, all the data is stored in the 1 TB.
When I inserted my new 2 TB harddrive, it was synced for three days. What did it do?
If I understand correctly about your words "the second disk adds RAID redundancy (RAID-1 mirroring), not more space.", it means by that now the data from the old 1 TB has been copied over to the new 2 TB. Am I correct?
I have bought another 2 TB harddrive, do I need to restart or do anything in the admin page before opening the case and removing the old 1 TB to replace it with another 2 TB harddrive? I only have two harddrive slots in my NAS.
My goal is to create 4 TB total storage, in my understanding I need to :
1. First, copy the old 1 TB to new 2 TB
2. Second, remove the old 1 TB replace it with another 2 TB
3. Finally, expand the total storage to 4 TB
Do I need flexraid for this? Sorry I am still a bit lost, thank you for your patience.
Thank you,
Eko

The RAID-1 sync copied every sector of the 1 TB drive to the 2 TB drive - so they are now mirrored. Anything written to the NAS now is written in parallel to both disks.
Three days is quite a long time for a 1 TB sync - what model 2 TB disk did you purchase?

If you are willing to settle for 2 TB of storage, then you can simply remove the 1 TB disk, and insert the 2 TB disk (with the NAS running). The volume will resync, and then expand to 2 TB. All data and settings would be preserved. The benefits of doing this are
- You would have protection from a simple disk failure, thanks to the RAID-1 mirroring. Note this doesn't mean you don't need a backup, as RAID volumes can sometimes fail.
- Further expansion in the future would not require starting over with an empty volume. Though you would have to purchase 2 larger disks every time you want to expand.
- XRAID is simpler, so it doesn't require as much knowlege on how RAID works.
If you want to create 4 TB of storage, then you need to use flexraid. The process isn't the same as what you are thinking. You'd first need to copy all your files to external storage (for instance a USB drive). Then you'd need to switch to flexraid, and destroy your current volume. At that point, your data and shares will be gone. Then upgrade the 1 TB drive to 2 TB. The next step is to create new volume(s). I'd recommend creating two 2 TB volumes (one for each disk), and then creating some shares on each. Then restore your files from the external storage.
While it is possible to create a single 4 TB volume with flexraid, I don't recommend that you do that. The reason is that when a disk fails (which will eventually happen) then you will lose all the files in the volume. If you create two 2 TB volumes, then when a disk fails you would only lose the files on that particular disk.
