====== ZFS - Testing ZFS Commands ======

ZFS pools can actually be installed not just on disks, but on anything with a descriptor in /dev that allows random access.

This includes:

  * Disks, such as /dev/sdb
  * Partitions, such as /dev/sdb1
  * Sparse files

===== Create a ZFS Pool with Sparse Files =====

<code bash>
for n in {0..7}; do truncate -s 1G $n.raw; done
zpool create -o shift=12 test raidz2 /tmp/*.raw
zpool status test
zpool list test
</code>

<WRAP info>
**NOTE:**  This will build a test pool out of sparse files in seconds.

  * This will show how much usable capacity will be available, which will be useful for when doing this for real.
