    Hey gang, kinda freaking out here as our server keeps crashing with the 50G root partiton saying its 100% full, but using du -sh *, all I'm able to see actually being used is about 13G. I've already moved mysql data to /home/ partition to save a few GB but can't seem to find where this ghostly 35GB+ is hiding. Is something broken on the partition?

    Results of du -sch * --exclude=home | sort -n

    Hello,

    Do you notice any hidden directories (directories that start with a period) in the / partition? These aren't scanned when using the "*" entry in the du command.

    Thank you.
