38 38  Let's start by creating a simple zpool wyth my 4 drives. I could create a zpool named "tank" with the following command:
39 39  
40 -{{code language="bash session"}}
41 -# zpool create tank sde sdf sdg sdh
42 -{{/code}}
40 +{{{# zpool create tank sde sdf sdg sdh}}}
43 43  
44 44  In this case, I'm using four disk VDEVs. Notice that I'm not using full device paths, although I could. Because VDEVs are always dynamically striped, this is effectively a RAID-0 between four drives (no redundancy). We should also check the status of the zpool:
45 45  
46 -{{code language="bash session"}}
47 -# zpool status tank
44 +{{{# zpool status tank

63 63  Let's tear down the zpool, and create a new one. Run the following before continuing, if you're following along in your own terminal:

72 72  In this next example, I wish to mirror all four drives (/dev/sde, /dev/sdf, /dev/sdg and /dev/sdh). So, rather than using the disk VDEV, I'll be using "mirror". The command is as follows:
73 73  
74 -{{code language="bash session"}}
75 -# zpool create tank mirror sde sdf sdg sdh

93 93  Notice that "mirror-0" is now the VDEV, with each physical device managed by it. As mentioned earlier, this would be analogous to a Linux software RAID "/dev/md0" device representing the four physical devices. Let's now clean up our pool, and create another.
