Error message when setting up log2ram on the Raspberry Pi.
Use log2ram to move the log files to ram instead of using the SD. Improves life of SD card by avoiding numerous writes to the card. https://github.com/azlux/log2ram
Detailed installation notes at https://pimylifeup.com/raspberry-pi-log2ram/
However, it does not cover this error message.
Check the size of the current log folder and set the value in the /etc/log2ram.conf file to be slightly larger. Ignore the notice that the max value is 128M. Mine was 176M so I set the conf value to 180M and everything worked after that.
Get size of current log folder: sudo du -h /var/log | tail -n1
