ReadyNAS NV+ RND4250: keeps booting since hours - unable to connect, not found by RAIDar
My ReadyNAS NV+ RND4250 worked for years (over 20...) without any problems. There are two disks in its slots. Few days ago the device stopped being accessible from my windows10 PC while daily increme...
The problem could be with the disks and not the NAS.
You could power down, and remove the disks (labeling by slot as you remove them). Then boot up the NAS, and see if RAIDar finds it.
If you have a Windows PC, then I also recommend testing the two disks with vendor tools (WDC Dashboard or Seagate's Seatools), and see if there are any problems. Run the long test, not just the short one (which is really only a confidence test).

Hard to say, since you don't have any progress information on the sync. But I think 12 hours or so would be reasonable for 2 TB drives.
thank you very much for your quick response 🙂
- is this device bootable without any disks inserted?
- if there was a problem with the disks, wouldn't their corresponding LED be blinking?
- what means the blue blinking power button (twice per second)?
Many thanks!
It's not fully bootable with no drives, but there is a bare-bones system it boots from flash that lets RAIDar see it and also can initialize new drives and install the complete OS to them.
The problem StephenB is referring to is a problem with the drive content, not a bad drive. The NAS boots from the drives in normal mode.
The flashing power LED just means it's booting (or powering down). It normally takes such a short period of time, it's hardly noticeable.
Thanks again. I removed firstly drive 1 and then restarted with disk 2 inserted (in its original slot #2),
the device LCD said:
"boooting..."
"Checking root FS"
"Checking FS"
"Quata chk: {counting}%"
and after that remains saying "booting..." (endlessly as it seems). Device not found with RAIDar. Forced shutdown.
Same procedure with just disk1 inserted (in its original slot #1). Exactly same behaviour and results as above, device not found with RAIDar. Forced shutdown.
Started again with no disks inserted, display says "ERR: no disks", 4 disk LEDs are flashing in the following sequence: all 4 LED on / off / LED disk2 on / off / all 4 LED on
Device is accessible in this state with RAIDar, however it is not via browser:
What do you suggest to do now (did not check the 2 2TB WD20EFRX SATA disks so far)?
