I'm running Debian 6.x

df -h tells me this:

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              19G   17G  696M  97% /
....

But these numbers don't add up...

# for D in $(ls -1 / | grep -vE "(home|media)"); do echo -n "$D ..........."; du -ch $D | grep total; done;
bin ...........6.0M     total
boot ...........14M     total

4.5G    total

I've rebooted and it reports the same. What am I'm missing? Where's the discrepancy?

Ah-ah...

I had a scheduled backup script that was propagating to /media/external-hdd but the script appears to be failing in it's check of whether the drive is mounted, causing it to use the actual mounting point as the target, filling up the root filesystem.
