Performance graphs
Hi all, I am curious as to why I now have no data in my performance graphs irrespective of the period I select. Any ideas??? I had an NTP issue a few days ago which set my clock back to 1st J...

I think that's just a side effect of the bad time. If you google, you'll see several other reports of this after NTP messes up.

I know but how do I get my graphs back... I'm thinking deleting the .rrd files will suffice but I'm keen to get feedback.

You've discovered a bug in the handling of a rewound clock by the thread that updates the graph data. If you don't reboot (or restart readynasd), you won't see any graphs for the next 14 years. :smileyhappy: The underlying issue here will be fixed in 6.7.5.

Thanks...
How can I safely restart readynasd on a running system without impact? I have SSH access.
Something else I've noticed too is that following each upgrade the historic data on the graphs is lost too, although this may be intentional.

You should actually be able to wake up the thread non-destructively by running this command once or twice:
# pgrep -w readynasd | xargs kill -HUP
