Influx Backup:

Also ich mache mein Backup von der normalen Linux Kommandozeile aus und nicht unter der Influxdb-Konsole...

Das schaut dann so aus bei meiner Datenbank die iobroker heißt:

Vorher muss aber die Influxdb.config bearbeitet werden...:

Hatte mich damals hiernach gerichtet und entsprechend meinen Anforderungen umgesetzt...:

Einen Restore hatte ich auch schon gemacht - ging problemlos.

Recently I got an error on influxdb. The log file was not clearly stating an error. But Health target was not reached. Starting the service stated to read the error log, journalctl -xe .

Finally I saw the config pattern:

LimitNOFILE=65536 which basically could limit the number of files the service oder user??? can occupy.

After commenting with # . The service starts succesfully.

This is not due to the case having more than 65k open, but perhaps in contradiction to system limits .

This solved my issues on ubuntu but not on my original raspbian.
