    MySQL... mmm, maybe a full root (OS volume being 100% full). Depending on how you installed MySQL, it often installs itself on the OS volume, with has only 4GB capacity. When MySQL gets big enough, then the OS volume gets 100% full and "break" the OS. Sometimes, there is no significant damage to the OS and moving the MySQL data to the data volume (+ symlink back) is enough, sometimes it's necessary to install a fresh OS volume. In both cases, your data volume remains untouched (so data is OK).
