“filename may not contain directory separators (Got “/home/boomballa/dragonfly/dragonfly16666/”)”

Does it mean that folder separators cannot be included in the configuration file? Or when the parameter --flagfile is used at startup, the configuration file does not write the full path? This point is not particularly clear.

--dbfilename=/home/boomballa/dragonfly/dragonfly16666/ this is the pitfall

3

you should just specify the filename without the directory

4

like --dbfilename=boomballa

5

it will be stored automatically in dir

@inclusive-numbat Ok, I got it, it’s working now, thanks.
A small suggestion, can you bring the parameters corresponding to the abnormality when reporting the error, as a reminder, it will be much easier to troubleshoot the problem. The error message looks very confusing. I thought there was a requirement for the name of the configuration file, or the specified configuration file cannot have an absolute path.

i agree. @dignified-nautilus FYI
