NV+ v1, Can/should I boot it without drives??
More NAS box fun!!
NV+A = Down for (4) new 2TB drives, fresh rebuild, no data. operates normally.
NV+B = Bad RAM, Data on (4) 500GB drives, no boot, data storage, rarely accessed.
Both are NV+ v1 (RND4000), running 4.1.8, X-RAID and the same age. Purchased within months of each other. 000D-A201-7E & 7F series S/N's.
I have data on NV+B I need to recover. After reading a number of posts that said I could because my NV+(s) are the same, I tried Installing the drives from NV+B into NV+A in an effort to pull the data. Kept the same order/drive slots. It would hang on 'booting....'.
Once I put the drives back in their proper NV+. NV+A will hang on booting..... C: 5.4/5.4T free" in the dispay. With empty drives. So now I am questioning the drive swap works at all.
The RAM fail happened on NV+B shortly after I updated to 4.1.9. First troubleshooting step I took was to do a USB Boot with 4.1.8 to get back to what worked. It didn't. So now I am not completely sure what firmware is on NV+B.
So can I, and is it advisable, to boot the NV+ v1 with no drives installed. Will it boot to a point I can determine what version firmware is installed? Or not at all?
I have new 1GB sticks coming for both units, should be here today. Here is another tidbit. I took the failed RAM from NV+B, (failed the memory test) and stuck it in NV+A before all the above was done. It booted just fine. So then I ran a memory test on NV+A on NV+B's ram and it failed. Tried to boot again and it did not. But the RAM back to original and now NV+A hangs at "booting...... C: 5.4/5.4T free" . I plan on rebuilding NV+A shortly to get things back to normal.
If I rebuild NV+A to 'fresh clean', are there any other options to get at least one of the drives installed and running in NV+A to be able to pull the data? Or am I gong to have to use Easus or other to recover the data?
Side question: Which drive is the 'spare' when four drives are installed using X-RAID? I wasn't aware X-RAID used a spare. I read the term 'spare' in posts from time to time.
And if someone knowledgable would, because I have never seen it on the forum, provide the steps it goes through when the NV+ boots. Kind of a "this happens, then this, then this....and if this doesn't happen then this is displayed, etc." That would help with my understanding of these units anyway. :wink:

It won't boot all the way, but RAIDar will see it, and at least give you a "no disks installed" status. I suspect it will not tell you the firmware version installed, however it is easy to try. If the NAS is powered down when you remove/reinsert the drives, the test should do no harm.ATG wrote: So can I, and is it advisable, to boot the NV+ v1 with no drives installed...
BTW, knowing the OS in the flash is not very useful, when disks are inserted, the NAS boots from the hard drive.
Rebuild it how? The OS partitions and data on on the 500 GB drives. If NAS-A boots with the 2TB drives, then it should boot with the 500 GB drives.ATG wrote: If I rebuild NV+A to 'fresh clean', are there any other options to get at least one of the drives installed and running in NV+A to be able to pull the data?

Since that fails, then it seems likely that is something going on with the hard drives. You could attempt to do an OS reinstall from the front panel. You could also try testing the 500 GB drives on a PC with the vendor's diags, and confirm that they are all ok.
When you installed the 500 GB drives in NV-a, was the NAS powered down?Rebuild it how? The OS partitions and data on on the 500 GB drives. If NAS-A boots with the 2TB drives, then it should boot with the 500 GB drives.
I agree, if it boots with one set, it should boot with another set. At least that's how I understood things to work.
Am I correct in thinking, at boot the NAS does not care what drives are in it? It will boot and then read the partition info from the second set of drives?
Rebuild meaning NV+A will be a new config from its original with new 2TB drives, restarting via reset button, let it do its thing.BTW, knowing the OS in the flash is not very useful, when disks are inserted, the NAS boots from the hard drive.
So with no drives the unit is basically "stupid"? Is this 'boot data' spread across all four drives, or just one? If so, which one? Trying to understand the boot process.
From above:...provide the steps it goes through when the NV+ boots. Kind of a "this happens, then this, then this....and if this doesn't happen then this is displayed, etc."
Or a link with this info would be nice to read through.When you installed the 500 GB drives in NV-a, was the NAS powered down?
Yes. Both were shut down, slot assingments kept the same.
My new RAM arrived today so I will play with that too.
