Collectd daemon errors - rrd_update_r failed?

Installing and Using OpenWrt

I'm getting some collectd errors in the log file. This group of errors occurs every few seconds. Any idea on how to sort this out?

R7800 with Hnyman

Thank you!

Do the files actually exist, and do the demon have permission to update them?

Yes, they all exist and are owned by root. I'm not sure what it means by..

This RRD was created on other architecture

I haven't done anything but enable collectd and point it to save content to USB.

And USB did not contain a previous rrd database?

(Rrd needs to initialize its own database, and one created by another router usually fails.)

No, I've only used the R7800 with your build. The USB drive has changed, but nothing else.
