Description Attila Fazekas 2019-03-18 09:30:12 UTC
Description of problem:
RHEL 8 guest image, has virtual disk size of 10GB,
The used partition size is ~8GB (/dev/sda1 reported by guestfish).  

The actual disk usage at the beginning  ~1.2GB.

The issue is, many thing (load balancers, frontends, vpn .. )
can work with very small disks
and in many cases you pay for the storage per gigabyte.

Just to compare:
Virtual size Ubuntu (18.04): 2.2GB
Virtual size Fedora 29:  4.0 GB

Please make the disks virtual size bellow 5GB,
so we would need to pay for only 5GB storage, instead of 10GB .

Please also try to make smaller gap between the disk size
and partition size if it possible.

If the smaller size changing anything on the default filesystem tuning
 parameter which does not auto-tuned on resize please keep to old ones.
