Ready NAS Duo v2 - LED blinkt RAIDar findet NAS nicht
Liebe Community, Vielleicht kann mir jemand weiterhelfen. Nach einem Stromausfall zeigt sich folgendes Verhalten nach dem NAS-Hochlauf. Die LED über dem backup Knopf blinkt und der Lüfter dreht seh...
I'm glad you got the data off the disks. Try powering up the NAS without the disks, and see if RAIDar can find it.
It should discover it, and report a "no disks" status.
If that fails, there is likely something wrong with the chassis (though there's a chance it's the power brick).
If it succeeds, then a factory default is the right next step.
Try powering down the NAS and removing the disks (labeling by slot). Then power it up, and see if RAIDar finds it. It should discover it, and give you a "no disks" status.
Thank you for your fast reply, I will try it. If this works is it then possible to insert the disks again without any data loss?
Do you know what firmware your NAS is running (it's either 4.1.x or 5.3.x)?
Also are you using the default XRAID (RAID-1)?

If it works, the problem is with the disks, and not the NAS chassis. If it fails, then you need a new NAS.
If it is the disks, then it could be that
- one (or both) disks were damaged when the power failed.
- there was some file system corruption because pending writes in the NAS cache were lost.
I think the best approach for data extraction (assuming XRAID/RAID-1) is to connect drive 1 to a Windows PC (either with SATA or a USB dock), and see if R-linux for Windows sees the data volume. If it does, then offload it to a USB or internal drive on the PC. http://www.r-tt.com/free_linux_recovery/
Hi Stephen,
Thank you for your help.
I removed both disks and tried the startup and it fails. It is the same behaviour: constant blinking led and RAIDar does not find the NAS. So this is now the point where I need a new NAS?
Regarding the firmware version: I am not completely sure but I think it is the older version.
regards,
Robert
