LVM Volumes wrongly sized on new AWS deployment

I deployed a new instance from AWS AMI version 1.17.2.

It stopped working in a few hours. It appears it ran out of disk space. 

Closer examination revealed that there is an incorrect LVM sizing. Also attached is the latest messages syslog.

Details below:
