Howto rename a Zpool and a ZFS mountpoint

I accidentially named a pool tets rather than test. So I renamed it.

zpool status -v

  pool: tets
 state: ONLINE
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        tets        ONLINE       0     0     0
          c0d1      ONLINE       0     0     0
          c1d0      ONLINE       0     0     0
          c1d1      ONLINE       0     0     0

errors: No known data errors

To fix this, I first exported the pool:

zpool export tets

And then imported it with the correct name:

zpool import tets test

After the import completed, the pool contained the name I had originally intended to give it:

zpool status -v

  pool: test
 state: ONLINE
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        test        ONLINE       0     0     0
          c0d1      ONLINE       0     0     0
          c1d0      ONLINE       0     0     0
          c1d1      ONLINE       0     0     0

errors: No known data errors
Step 2 Fix the also messed u ZFS Mountpoint
I've used this Mount for a Zone so thats why I placed it into /opt/zones/$Servername
zfs set mountpoint="/opt/zones/[Newmountpoint]" [ZFSPOOL/[ROOTor other filesystem]
