That's one of the advantages i see in ZFS. Do you use it frequently? Can anyone comment on its memory usage (without dedicated SSDs for ARC)? Maybe i'd use the 4 drives as a ZFS pool. For now LVM complains about duplicate PVs (when pvcreate /dev/md0), i'll have to fiddle with the filters in lvm.conf
