Mosquitto cannot write log to SD card

[Hualin]

I change the mosquitto.conf to make the Mosquitto write log to a SD card. But it continually said mosquitto cannot open that log file. I already make the file available to everyone (by "chmod 666" for that file).

@Hualin are you writing directly to the file via its device path or are you using a symlink?

I faced similar kind of issue last time, I am still searching for some proper solution!
