[SOLVED] Error with rrd4j. Evertime editing rrd4j.persist Exception occurs (Openhab 2.2.0)

Add-ons Persistence Services
1

Everytime I edit rrd4j.persist the Exception (down under) occurs.
No persistence state is stored in /var/lib/openhab2/persistence/rrd4j

The strange thing is, that it worked until last weekend. Now I can’t persist the state of the items.

/etc/openhab2/persistence/rrd4j.persist:
Strategies {
everyMinute : “30 * * * * ?”
everyHour : “20 0 * * * ?”
everyDay : “40 0 0 * * ?”
}
Items {
* : strategy = everyMinute, restoreOnStartup
}

Output in openhab.log:
2018-06-02 22:35:30.577 [INFO ] [el.core.internal.ModelRepositoryImpl] - Refreshing model ‘rrd4j.persist’

Anyone an Idea, what’s going wrong?

Try deleting the file and create a new one. BUT type in the new file don’t copy and paste. You may have one or more rogue invisible characters in there causing the error.

Hi, thanks a lot.
now the Execption isn’t thrown any longer, but the files in
/var/lib/openhab2/persistence/rrd4j
aren’t updated, so I think, the state of the items aren’t persisted…

4

Did you restart OH? After creating the new rrdj4.persist file?

5

Yes I restarted… Still the same

Had to delete all files in /var/lib/openhab2/persistence/rrd4j/
Afterwards rrd4j was running…
