Welcome to Ask Ubuntu! The space on sdb5 is most likely fully taken by the LVM physical volume, you can see it by running
lsblk. Can yourducall access all the files (i.e. doesn’t it print any errors)? Consider running it withsudofor the root directory.– Melebius

To help find where the space is used, try
cd /and thensudo du -aBM -d 1 . | sort -nr | head -20- this command will take a short while to run the first time, as it scans the directory tree, but you can then descend into the larger directories to see where the problem lies.– Charles Green

Thanks Charles. Added that output above as well as it came up with a few du errors which may be of relevance to the problem?

@Neabhan second thing: If you plug in a drive and use /mnt normally say for backup? But for some reason one day, your drive is not plugged in while backup is running, then the files get written to subdirectories under /mnt - when the drive is plugged in, those directories are masked and you cannot see them.

@Neabhan Final thing: Modify the command to
sudo du -xaBM -d 1 . | sort -nr | head -20(added -x option) and it should not cross filesystem boundaries.– Charles Green
