You might set zil_disable to 1 (_then_ mount the fs to be

still corrupt your nfs clients.
For the love of God do NOT do stuff like that.
Just create ZFS on a pile of disks the way that we should, with the
write cache disabled on all the disks and with redundancy in the ZPool
config .. nothing special :
# zpool create -m legacy -f zpool0 mirror c2t8d0 c3t8d0 mirror c2t9d0 c3t9d0
mirror c2t10d0 c3t10d0 mirror c2t11d0 c3t11d0 mirror c2t12d0 c3t12d0 mirror
c2t13d0 c3t13d0

The create some filesystem in there :
# zfs create zpool0/test
Give it a mount point :
# zfs set mountpoint=/test zpool0/test
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
zpool0 98K 1.60T 1.50K legacy
zpool0/test 24.5K 1.60T 24.5K /test
Maybe set a quota :
# zfs set quota=400G zpool0/test
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
zpool0 98K 1.60T 1.50K legacy
zpool0/test 24.5K 400G 24.5K /test

For NFS just share it. Nothing special at all :
# zfs set sharenfs=nosub\,nosuid\,rw\=nfsclient\,root\=nfsclient zpool0/test
# zfs get -o property,value,source all zpool0/test
