Source:
zpool with samba user home folders: poolz2/samba/usersAllow request about quota for everyone:
zfs allow everyone userquota,userused poolz2/samba/users
Set usrer quota 120G for domain user : DOMAIN\username
zfs set userquota@"DOMAIN\username"=120G poolz2/samba/users
Tune SAMBA, /usr/local/etc/smb4.conf:
get quota command = /mnt/poolz2/home/scripts/quota_get.sh %U %D
Reload SAMBA:
killall -HUP smbd
Or change via GUI of FreeNAS
