/Var on ZFS Problem

Hi,

i upgraded my server and now i want to move /var onto a radz2 pool.
System: Centos 7 with zfs-kmod

What i tried by using Ultra slow ubuntu live us (15 mins for booting each time, done about 10 times>.<) :

Copy var -> var2, delete var , cp var2 into pool mkdir var , set mountpoint to /var reboot ==> fail

The same thing with legacy mointpoint and fstab mounting (https://bbs.archlinux.org/viewtopic.php?id=160825) --> failed dependencies at mounting (!?!)

A mix out of links and bind mounts (https://matthias.benkard.de/journal/111) is again... not working

Total time wasted in this: about 8 hours. Edit 11h.

Could someone help me out with this bevor i loose my mind....

greetings

Zee Captain
