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 incremental backup job was running. Since shutting down gracefully (for reboot purpose) did not work that way I forced shutting down the device by unplugging it. After plugging it in again and restarting it by pressing the power button "normally" (shortly), the device did a "quota check" (message on front display) sucessfully (100%) and then prompted the message "booting..." on the display, furthermore I got an e-mail with message text: "RAID sync started on volume C". [Thu Jun 13 09:10:41 CEST 2024]. In this state it is now since more than 7 hours: In the displays it says "booting...". The LED of the 2 installed disks light in steady green, the ACT LED is off (see photo) and the power button is blinking blue (once in a second or so). I tried to access the ReadyNAS from a Windows7 PC as well using RAIDar, without success. The device responds to PING command from windows command prompt normally, however it is not connectable by using e.g. NET USE command.
- for how long does it make sense to let the device "booting..." before force it to shutdown?
- what steps should I perform after shutdown?
- is it e.g. worth trying to re-install the OS?
- what do you recommend further to access the data on my disk(s) again?
btw: when trying to acces the device with a browser (Frontview, https://IP-address/admin/), on a Windows7 PC the http request is answerd with just the HTML "frame" of Frontview and that's it (see screenshot).
Thank you for your help, appreciate it.

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.
