I could recreate and can confirm the same for groovy.
If the installation was started with:
sudo virt-install --name groovy --memory 2048 --disk
path=/dev/disk/by-path/ccw-0.0.1601 --cdrom ./groovy-live-server-s390x.iso
the installer uses /dev/vda that is usually an indicator for virtio device
rather than a DASD disk (the size of 6.877G is the correct net size of the used
DASD Mod9 disk):

Configure a guided storage layout, or create a custom one:
(X) Use an entire disk
[ /dev/vda local disk 6.877G ▾ ]
[X] Set up this disk as an LVM group
[ ] Encrypt the LVM group with LUKS
Passphrase:
Confirm passphrase:
( ) Custom storage layout
[ Done ]

I've added /var/logs and /var/crash.
