I performed a dist-upgrade (on my Druapl appliance) which upgraded apache, webmin, and a couple of other packages. I have not installed any other packages except whois. Now, I get this when I try to run MySQL:
ERROR: The partition with /var/lib/mysql is too full!
Indeed, df says that /dev/sda1 is completely full.
I have an ebs volume attached to this instance, so I can move stuff around. But there is nothing large on /sda1. I have not stored much there (about 130M).
