Hm, --reset-database doesn’t work, on NAS. I stopped syncthing and executed
./sycthing --reset-database
and syncthing silently exited. I hoped it did its work, but evidently it didn’t. According to Effect of parameter | -reset-database // -reset-deltas, this command should remove the folder /var/packages/syncthing/target/var/index-v0.14.0.db/, but it did not :-(. Can I remove the folder manually?
When I executed
./syncthing --reset-deltas
syncthing started and - according to its log - it performed what it was expected to do.
