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!

Great feedback. Thank you.
Can you share the exact approach you take to your NAS to NAS backup? Is it Rsync (if so, what's the command) or something specific within the ReadyNAS environment? Is it proprietary to ReadyNAS, meaning, would the backup be recoverable or transferable to a non-ReadyNAS NAS? While I'm seeing a lot of discussion on Rsync, most are people who can't resolve problems, and involve rsync'ing between similar NASs (i.e., ReadyNAS to ReadyNAS).
On the OS6 upgrade, is that as simple as downloading the lastest version from the Netgear website and doing a 'local' update? Of course, my current Pro 6 doesn't see an updates availble...

I use rsync backup jobs in the ReadyNAS. These work with other linux systems (including competing NAS).
You can set these up either as "pull" backups (where the source directory is on the other machine), or as "push" (where the destination directory is on the other machine). I use "pull" myself, and have one backup job for every share on the main NAS. The backup NAS is on a power schedule, and boots itself up shorty before the backups are scheduled. After the backups compete, the NAS shuts itself down. These backups are run daily.

No, it's not that simple. The steps are
(Optionally) make sure the latest BIOS is installed before you do the conversion. To do this you install http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin as an add-on and reboot the NAS. Do this after you backup the NAS. This isn't necessary, but if you so want to update the bios it is easiest to do it prior to converion
Basic instructions for the conversion itself are
- BACKUP, BACKUP, BACKUP
- Upload PREPR4TOR6_0.1-x86.bin as an add-on using the ReadyNAS web gui, but do not reboot afterwards (avoids the need to do manual factory resets)
- Upload R4toR6_6.9.5.bin using the ReadyNAS web gui firmware update
- After you upload the addon+firmware and reboot, it will update the firmware and start a factory default.
- Go through the setup process on the converted NAS
- Update the NAS to the current OS 6 (check for updates will work).
- Restore files from the backup.
Netgear won't provide paid support on a converted NAS, so that is one consideration. There is a small risk that the process could fail, and if that were to happen it might not be possible to get the NAS running again.
If you do decide to convert the Pro, then you should also consider increasing the RAM. Shipping OS-6 NAS have at least 2 GB of RAM, your Pro only has 1 GB. It will work, but it would be sensible to match the resources in the currently shipping NAS. The upgrade is inexpensive, and is simple to do.
