creating a basic volume mounted for usage as type "Directory"

# clean device of any partitions or filesystem metadata
wipefs -a /dev/fioa

# create new ext4 filesystem across disk, no partition necessary
mkfs.ext4 /dev/fioa

# append mount instruction to /etc/fstab

Upgrading the ManageIQ appliance

I've been working to upgrade ManageIQ, and there are a few paths you can take with this.

Deploy a new appliance, load configs and database on
Deploy from scratch, load configs and database on
Upgrade the app upon the existing appliance

For this article, I'm examining the final option: upgrading the application upon the existing appliance. Guide will be written against my existing manageiq-dev server. If other options prove more viable I'll write about them as well and re-arrange this!
