performance statistics are not saved

Hello

I´m running omv on a odroid-xu4 with two 3TB USB 3.0 drivesmainly as nas. A few weeks ago I connected a third external drive due toa big copy job. Maybe i forgot to unmount the disk, because since thatday the performance statistics are not saved anymore. That means Ican see all the statistics clearly for the actual day. But when Idisconnect the odroid from the power supply the statistics are gone. Thats pretty annoying as i shutdown the nas every night.
I already tried:

rm -r /var/lib/rrdcached/db/localhost


rm /var/lib/rrdcached/journal/*


service collectd restart


service rrdcached restart

looking forward to your assumptions.

Omg it was really that simple. Due to the big copy job I deactivated the auto shutdown script and the clock timer. But for some reasons I afterwards turned on only the clock timer again, so every night the odroid have been unplugged without a shutdown.

Thanks a lot for the hint!
