Activate ACL for zfs pool ubuntu 13.04

i have tested ACL on local folders and i works perfect.

But on my zfs pool called "tank"

root@datacenter:/mnt# ls
datatank  test  webmin_1.650_all.deb
root@datacenter:/mnt# setfacl -m u:casper:rwx datatank
setfacl: datatank: Operation not supported

How can I add acl support for my zfs system ?

Whats wrong ?


Solution 1:

Use

zfs set acltype=posixacl tank/datatank
