Hi ZFS fellows, I already seen on the archive of the list some of you doing some GUID change of a pool''s VDEV, to allow a cloned disk to be imported on the same system as the source. Can someone explain in detail how to achieve that? Has already someone invented the wheel so I would not have to rewrite a tool to do it? Subsidiary: Is there an official response of Oracle in front of such case? How do they "officially" deal with Binary Copied disks, as it''s common to do such copy with UFS to copy SAP environment or Databases... Thanks in advance, Thomas
