ZFS: Renaming a zpool

  If you’ve imported a pool from another system and want to change the name or have just changed your mind, this is actually quite straightforward to do. Run the following (as root):

zpool export [poolname]

As an example, for a pool named tank which we wish to rename notankshere:

zpool export tank

Then run:

zpool import [poolname] [newpoolname]

e.g.:

zpool import tank notankshere

  The pool will be imported as “notankshere” instead.
