Hi everyone!! I'm making practise with a NAS and I can't create a new RAIDZ with 3 hard drives. When I click on "Add volume" appears this message: Unable to GPT format the disk "ada0" I tried to export the volume marking to destroy the data, rebooting and trying to create the volume another time and it's appears the same message. It's like the old configuration of the RAID can't be deleted, when I click on autoimport volume (after exporting it) appears the old RAID I create. Can somebody help me?? Thanks!
