1. Yes, compression is on for the parent and inherited. The ratio only shows 1.37x, which seems rather low if a 12T file was all zeros except for >10G?

root@fusion:~# zfs get all rpool/DATA/fusion/store/vms/plexee | grep comp
rpool/DATA/fusion/store/vms/plexee compressratio 1.37x -
rpool/DATA/fusion/store/vms/plexee compression lz4 inherited from rpool

2.
root@fusion:~# du -h /data/store/vms/plexee/plexee-root
5.6G /data/store/vms/plexee/plexee-root

This is what I would expect the VM to be using based on how the file was provisioned and its internal disk state.
