using 16.04, it kept running fsck on boot-up. So I tried to find where all the fsck logs might be. Another askUbuntu thread suggested /var/log/upstart/mountall.log
But when I looked in /var/log/upstart/ there was no log files, only compressed files. It seems to be the case for all other types of log files in there. Even the compressed files only few bytes in size and can not be opened.
There seems to be a bug which covers this
Is there any way to get it to write to log
