Data Recovery readyNAS 2304

Hi Guys, 

we used to use a RN2100 which stopped working after we tried to shut it down. we've never got it running again. The netgear support suggested that we buy a ReadyNAS 2304. So we did and put the old drives into it.
Now the shares do appear but the system seems not to be able to access the drives.
Tried to boot the machine in volume read-only but that doesn't seem to work either.  

No volume icons show up.
Is there any way to recover the data from the disks?
Any help appreciated!

It definately rund Raidiator


This process should have worked then:  https://kb.netgear.com/29957/ReadyNAS-Migrating-disks-from-RAIDiator-4-2-to-ReadyNAS-OS-6-x86

 

Can you access the admin web ui of the NAS, and post a screenshot of what you see there?

Re: Data Recovery readyNAS 2304

Did you just try to migrate the drives?

 

That wouldn't work with a 2100, unless it was running 6.x.x fimware.  It should have worked if you migrated from an RN2120

 

Can you confirm what you were migrating from (ideally telling us what firmware was running on the old NAS), and how you migrated the drives?

Volume read-only mode is a boot menu for volumes created on OS6, not for data recovery attempts of volumes from a system running RAIDiator.

Re: Data Recovery readyNAS 2304

i need to talk to my collegue to answer the questions about the old machin's firmware version and if he did anything to migrate the data.

The 2100 simply was there so we used it. i would be very happy never to use it anymore again. While i would be even more happy to see my data again 

let's assume that it was running on an earlier firmware version - like 4.x.x. What options do we have?

Re: Data Recovery readyNAS 2304

i started a test disk procedure which lead to nothing but flashing red lights on the disks. Can i exit that procedure or does it lead to data loss?
If i can exit it i can restart the machine and enter the web ui and post screenshots

Re: Data Recovery readyNAS 2304

Aborting a disk test wouldn't lead to data loss.

 

initrd.log shows that the 2100 was last factory reset way back on RAIDiator-x86 4.2.5. I believe that was probably the firmware we shipped the first 2100v1 units with (either that or a firmware or two before it).

I think your old unit was a 2100 v1, so it would have the 32-bit utilities needed for that on the root volume. For the migration procedure to work in my experience the 64-bit utilities used by our legacy x86 models that have 64-bit CPUs are needed.

 

The disks look healthy and the RAID looks fine and there's plenty of free space on the data volume so I suspect that extracting the RAIDiator-x86 root files onto the root volume would resolve this, but it would be impossible to know for sure without having a remote look at the system.

Re: Data Recovery readyNAS 2304

After a few detours we found out that this process did work!
Thanks for the hint!
We're backing up the data right now. 

Thanks a lot for the help!

How did the backup go?

Re: Data Recovery readyNAS 2304

no issues (except for minor owner/user/group rights hassle). We used Carbon Copy Cloner to get everything off the machine. Due to read-only there's no syncing option so we had to manually keep track of unscopied files. But we did that, updated the machine to OS6 and at the moment we're copying the data back on the NAS.

Everything fine. no data loss at all.
We're very happy with the new machine (less noisy) the speed is great and OS6 looks very good. 👍
