 **Warning**: The following will find all drives on the system, including your boot drives, so remove the boot drives before proceeding with the zpool creation.
+**Note**: I've shown three ways to find the drives on the system. The first three commands give redundant information. If you have smartctl on your system, that is probably the easiest, since it has a scan function built in, but geom is FreeBSD's way to do it.
 <code bash>

 geom disk list | grep Geom | rev | cut -d' ' -f1 | rev | sort

 This will create a pool named storage, mounted (-m) at /storage, forced to ignore most drive errors. The pool will be a raidz2 (aka RAID 6) with 6 drives (4-9), and have a dedup vdev consisting of a mirror from da2 and 3.
-===== Set defaults =====

-Your new zpool may not have the default values you want. This is simple enough to do at this point, then any datasets/volumes you create will default to the following values.
+Your new dataset may not have the default values you want. It is simple enough to set defaults for all child datasets at this point, then any datasets/volumes you create will default to the following values.
 This is the way I have most set up. Modify it for your own use. Pay particular attention to the dedup=on and compress=gzip-9.
