ReadyNAS Ultra 4 OS6.9.4 powering down
I recently upgraded my Ultra 4 to OS6 and everything appears to be working great. However, after I left home for Christmas my NAS went offline. When I got back from vacation last night, the NAS was...
I suggest changing the schedule (lower screen shot) to always on, and see if that solves it.
If it does, then try enabling and then disabling the power schedule again (changing the schedule itself back to what you have now).
Is it possible that there was a glitch in the power?
I once had a similar problem, and the power supply died a few weeks later. After replacing the supply, the issue never again occurred, so I assumed they were related. I believe the NAS thought I turned it off (and, thus, no message as to why).
The power on/off circuit uses the 5VSB power, which is one of the most fragile since it stays on, even when the NAS is "off".
It could be something else, but be aware that you could be going down the same path.

Okay. The hardware has been reliably on for several years so this seems pretty new and likely related to the switch to OS6. But it could be a coincidence.
The only other hardware change was a switch from 4 1TB hdd's to 2 4TB (WD 5400rpm Reds) hdd's. But that should lighten the power load
Looking at the logs both times its shutdown was at 5am, which seems too consistent to be a coincidence. But as far as I can tell, there's no scheduled shutdown enabled.
Dec 24, 2018 05:00:09 System: The system is shutting down. Dec 31, 2018 05:00:08 System: The system is shutting down. The power timer is unchecked.
Though there does appear to be some kind of power transition at 5am on Mondays. But if I read the graph correctly I'd expect it to turn on then, not off... And I'm not sure why it would take effect if the box isn't checked. Note I did not touch either of these settings, although before the upgrade in OS 4 there was reboot event set for Monday mornings. Perhaps this carried over poorly.
