Migrating NV Disks after PSU failure
Have a ReadyNAS NV for a number of years that had a PSU failure (hot, funky smell and rebooting) and the unit was covered under the service bulletin.
I had expected Netgear to send me a PSU to swap out. Would have been easy enough. However, they didn’t have a PSU in stock so they sent me today a ReadyNAS NV+. I believe its V1, as they are replacing a Sparc unit. It’s silvery metallic, so I think it must be V1. It's the same as the old one, except for the LCD screen at the bottom of the front. The new model number is RND4000-100NAS.
Here are my questions.
Before the PSU died, the original NV had 3 2GB disks operating on Radiator 4.1.8 ( I believe). RAIDar is 4.3. All was working fine until the overheating. I don’t think the original disks were damaged asI caught the problem quickly, though can’t be 100% sure. Netgear tech support said just to pop the old disks into new unit in the same order and all will update. Neither they nor I have any way to know what version of Radiator is on the replacement diskless unit. I want to make sure I do this right. I can’t take chances on losing the data.
What precise steps should I take and in what order?
I have extra empty hard drives that I could use to ensure the new device is working and update the firmware before adding my old drives. If I update the firmware to 4.1.10 and then power down. Would I just insert my old disks and fire it up, which I think were on 4.1.8.
One other nuance. My desktop PC that is the home to RAIDar is an old PC with its own problems. I can’t update RAIDar software or any software for the time being now. As long as I don’t update RAIDar, it’s fine. Can I ALSO access the unit from any other computer running RAIDar, including my laptop? Do I need the laptop to be hard wired to the router as my desktop currently is?

- The NV+ (v1) is the NV with a few evolutionary hardware improvements + a LCD: http://www.readynas.com/kb/faq/pre-sales/what_is_the_difference_between_the_readynas_nv_and_nv
It's pretty much the same hardware and migration will be smooth.mas99 wrote:

Yes that should work. Though I would update the system to 4.1.8 if that's what you were using previously. It is a good idea to update the firmware using a spare disk before doing the migration just in case the flash has very old firmware on it.mas99 wrote:

It just needs to be on the network. It can be wireless. If RAIDar isn't working over wireless then there could be a settings issue in your router.
The I.P. address should show on the LCD of the NV+ (if it is off momentarily press the power button and it will come back on). You can go to Frontview directly: https://ip.address.of.nas/admin
The migration instructions are here: http://www.readynas.com/kb/faq/boot/how_do_i_migrate_disks_over_from_an_existing_readynas_to_another - Thanks, mdgm. You've helped me through a number of transitions over the years. Always much appreciated. The one issue is I'm not 100% sure the old unit was 4.1.8. I could try to fire up the old unit. It wasn't completely fried, but had gotten so hot it was continually rebooting. Would it be worth it to try to power it up with or without the disks? Can RAIDar see it without disks in it?
- I don't think I would power up the old unit again.
If unsure you could just update the replacement unit to 4.1.10. - I put in an old used disk to update the firmware. Firmware was 4.1.6 and I updated it to 4.1.10. When it rebooted, it shows the disk healthy, host name is still the old host name and it sends me warnings it can't find my listed shares (the original shares). Since they aren't on the disk that seems to make sense. It also says the volume is empty, though the disk in there is a 400GB disk. Does this all makes sense too?
If all this seems right, all I should do then is power down, insert my original 3 disks and start it up. It will then update the disks to 4.1.10 and I should be good to go?
The old shares should all be there and accessible. Does that sound right?
Just being careful. I have a lot of data on these disks. - Yes, power down, remove the spare disk and migrate your disks across following the instructions in the FAQ
- Will do, mgdm. Thanks for that exceptionally fast reply.
Thanks - File check and resync worked. Since I had updated radiator in the new NV+ from 4.1.6 to 4.1.10 with an old disk inserted, I expected it to still be 4.1.10 when i reinserted the older 3 disks and finished the resync. However, it remains at 4.1.8, which is the version I guess I had before the PSU failure. Do I need to update again with the current set of disks?
- Yes, the firmware is on the disks as well as on the internal flash. So while your disks have 4.1.8 on them 4.1.10 is in the internal flash of the unit.
An OS Re-install via the boot menu or installing 4.1.10 again will make sure the firmware on the flash is the same as the firmware on the disks. - Is one safer than the other? It would seem if I don't want to reset anything (like password or IP), installing 4.1.10 would be better?
If I opt for OS reinstall, it's just power off, press reset with paperclip in the back and press power to restart. In this case data remains safe? mas99 wrote: Is one safer than the other? It would seem if I don't want to reset anything (like password or IP), installing 4.1.10 would be better?

If you don't want to reset anything then just install 4.1.10 over the top of itself. An OS Re-install would reset the admin password and get the NAS to pickup an I.P. address via DHCP.mas99 wrote:

You would power down, press and hold reset button, press power button, after about 5 seconds the disk LEDs will blink once and the LCD will show something like "5: OS Re-install". Release the reset button at this point.
