25% of my disk space appears to be missing
 

Something very odd is happening on my debian box.

du -ks / shows I'm using 12.5 GB of my 19.2 GB disk

df -ks shows I'm using 17.7 GB

I only have two partitions swap which is 500MB and my main partition.

How could I be missing over 4 GB?

-ethan

it'll probably make a lot more sense if you run "df" instead of "du", if not, give us the whole "df" output

Does this help? Below is my df output and my du output and the output of sfdisk showing that I have only two partitions.

So my question again is where is the missing 4+GB?

Is there any util that can give me more information?

This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.

Input in the following format; absent fields get a default value.

Usually you only need to specify <start> and <size> (and perhaps <type>).

mysqld had a 5 GB deleted file open

I determined this with lsof +L1

apparently msqld wasn't rotating logs properly
