Today my disk got full. It was surprising, because I've been running the same automated script for a few months, with plenty of space, and no issues.
I don't understand where it's gone.
du reports only 26 GiB used, which is what I expect.
root@data3:/home/upload# du -hs / 26G /
df reports me that I'm using 46 GiB:
root@data3:/home/upload# df -h Filesystem Size Used Avail Use% Mounted on rootfs 52G 46G 4.0G 92% / /dev/root 52G 46G 4.0G 92% / devtmpfs 2.0G 4.0K 2.0G 1% /dev none 395M 224K 394M 1% /run none 5.0M 0 5.0M 0% /run/lock none 2.0G 0 2.0G 0% /run/shm
I looked everywhere for big files, and didn't find any other than expected.
Here's is fsck results

This is a SSD drive. I've been writing/erasing about 15 GiB a day since July.
Where did my 20 GiB go? What should I check?
