Here's an example: [chinatsu]:/root# zfs userspace tank TYPE NAME USED QUOTA POSIX User root 6K none [chinatsu]:/root# zfs set userquota@takeda=5M tank [chinatsu]:/root# zfs userspace tank TYPE NAME USED QUOTA POSIX User root 6K none POSIX User takeda 5M Please note that the above command updated USED value and not quota. As I show later the USED value is not updated based on storage usage and the quota is not enforced at all. I don't think it is necessary, but I also compiled the kernel with "options QUOTA".
