ReadyNAS Pro 6 won't boot after failed drive addition

I've had a ReadyNAS Pro 6 (v2) for about 5 years without issue. I can't recall the OS version, but it is the latest from Netgear. Five bays hold 3TB disks configured for RAID 5 (disks are Seagate ST3...

Everything is back to normal and working fine. Many thanks to Sandshark and StephenB ! The problem was the power supply. Once I hooked up an old ATX supply harvested from an old computer, the system was able to complete the restriping and resyncing need to add the sixth disk. I now have plenty of head room and can begin a migration to a new system.

I'm finding some references to those who use rsync between a FreeNAS server and a ReadyNAS server. I might do that instead of buying a large external USB drive, and then use my existing ReadyNAS as my backup to the new server once I build it. Any comments on that would be appreciated.

Thanks again!

Thanks for your reply and willingness to help.

I removed all the drives, and the system does not boot past "ReadyNAS". I also discovered that I cannot enter the boot menu, with either disks or no disks installed.

So I have a chassis problem?

Sounds like it. Can RAIDar see the NAS w/o disks? https://kb.netgear.com/20684/ReadyNAS-Downloads

RAIDar does not see the unit. Sorry, I should have pointed that out before.

I have lots of fan noise, but otherwise, nothing except "ReadyNAS" on the device display...

Thanks again for your help.

What to do??

  It could be the power supply - and with some effort that can be replaced.
  
  If you don't have a current backup:
  
  If you purchase a new OS-6 x86 ReadyNAS (RN300 or better), you can temporarily mount the Pro-6 disks in the replacement NAS so you can copy off the data. https://kb.netgear.com/29957/ReadyNAS-Migrating-disks-from-RAIDiator-4-2-to-ReadyNAS-OS-6-x86 If the RAID array isn't fully in sync (likely given the failure), you likely would need a data recovery contract from Netgear. https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
  
  If you can connect the disks to a PC (likely in an USB enclosure), you might also be able to extract the data yourself using R-Studio RAID recovery software ( https://www.r-studio.com/ )

    I agree this is most likely a hardware issue and that the power supply is suspect #1. The NAS will display "ReadyNAS" even if only the 5V power is good.
    
    The supply is an SFX form factor drive, which is available (though the original Seasonic one is not). Not quite so available are ones with the required 3 4-pin Molex connectors and a long enough acble. SATA to Molex adapters and a 24-pin extension can be used to overcome those. There is someone on eBay who advertises one that's compatible without any extenders.
    
    It could be something else, of course. Bad RAM is another that's repairable.
    
    If you have a spare ATX power supply handy, it can be used externally to both confirm the problem is the power supply and to recover your data, should you decide not to move forward with a power supply replacement.
