Copy from NAS HD to new HD
Hi, I have two ReadyNAS 626x same OS same features 1- ReadyNAS 626x two HD each ( 10TB ) and on RAid 0 it has all my data. 2- ReadyNAS 626x no HD I'm buying two new HD (12TB) . my que...
well this is one of normal solution but my target is copying that much of data (20TB) to another inserted HD would be faster since
its done locally its matter of copying files ..
transfer over network will take too much time ..
my easy solution would be copying it to external HD via USB.
I wrote an email to Netgear they couldn't provide me with the proper answer
- is it possible to have more than 1 raid 0 in single NAS ?
if I'm already having two HD are set to raid 0 .. can I ad another two also raid 0 ? then remove it
and put it in another NAS ?
It is possible, but there are risks. Because of those risks, you'll want to insure you have a full backup of your data first (which kinda eliminates the benefits of doing it).
It becomes a bigger problem if you have apps installed. I don't recommend you do it if you do, unless you can un-install them and re-install afterward.
But the process is this:
- Make sure you are in FlexRAID. Special note: If your NAS decides you have "expanded volumes" (which I think means multiple RAID groups), you will be prevented from going back to XRAID later.
- Add the new drives, format them, and create a new volume.
- Copy the necessary files. Backup jobs are still the best here.
- Power down and move the new drives to the new machine. Do not "EXPORT" the volume, doing so will make it not work as a primary volume on the new machine.
- Power up each. On each, you will see it complain that there is a missing volume. DESTROY that missing volume.
- Both will also have the same network ID, so change that. If you use a static IP, you'll have to power up just one and change that first so they don't conflict.
- You can also now try to go to XRAID if you want that, but it might refuse.
- Now, here's the risk: On both machines, your original volume was marked as the main one, so it contained your home and apps folders. But you destroyed that on the new machine. The OS is supposed to create new ones (that will be unpopulated), but I've seen that fail. It's fixable via SSH, but not simple.
- If you need user folders, the users will have to log in to the new machine for them to be created or you can use mkhomedir_helper via SSH to create them.
- Note that the GUID for both machines will be the same. I'm not aware of that causing any problems, but I may simply have not come upon them.
it seems complicated more than what I thought!
just to be clear the both machines are in different house and I planned to full the HD with data from my main house then later
take just the two new HD and fix it in the other machines ..
anyway it looks like have to copy manually to external HD 4TB at time till I complete the transfer

I think a better plan is to start with both NAS in the same house, and then use backup jobs to copy the data. That will go faster than manually copying (since they can run 24x7). Then move the new NAS with the new disks to the new house.
Hi
Ok if I decide to do NAS to NAS is there special approach or settings ?
or just brows the two NAS via laptop ?
