 +Steps:
 +* Create the pool of disks with zpool.
 +* Move data in the disks. ​
 +* First test #1: unmount the disks, reshuffle them and mount them again. Pool of disks succesfully detected.
 +* First test #2: mount the disks in another machine and detect the raid there. Pool of disks detected OK, but in read-mode only. Possible error due to different zfs versions. ​
