I had a system that ran out of space due to the journal getting full. So I vaccumed that and recovered the space, but while looking at that, I noticed that the system is using half it's drive space on /dev/vda1 but I can't figure out where the rest went.

Shutdown and rebooted, then ran ncdu as root - no help. What else can I check?

A comment at the following link pointed me in the right direction.

I unmounted my backup drive - /mnt/BACKUP

Then I looked on the local file system (/dev/vda1) and found /mnt/BACKUP folder that had a huge backup in it. So /mnt/BACKUP (the real external drive) must have go unmounted and then the backup happened, then the external drive got mounted. Odd, but fixed now!
