Hi,
I'm having some issues with a FreeBSD box using ZFS to serve iscsi to other
boxes.

As you can see, the zpool is at only 23% of it's capacity. However, if you get a
list of filesystems with "zfs list", you see that there is only 138GB free space
left.
[root@storage ~]# zfs list

These are fiesystems that are created with the following command. zfs create -V ${size}GB ${ZFS_ROOT}/${diskname}
`zfs create -V` withous `-s` creates reserved volume that eats all needed space immediately. Technically zfs pool is filled only for 23%, but logically you have only 138G left unassigned.
