Prepare disks to be able to use with ZFS
Posted: 06 Mar 2015 17:32
Hi,
i want to prepare my 4 X 2 TB disks to be able to use it with ZFS. I had this disks already in use with FreeNas. But now i want to delete everything and want to prepare the disks to use it in production with Nas4Free. Is it enough to overwrite the first and last sectors with NULL. See http://wiki.nas4free.org/doku.php?id=faq:0129
Or is it better to overwrite everything on disk with NULL
Thanks for comments

Code: Select all
dd if=/dev/zero of=/dev/ada0
dd if=/dev/zero of=/dev/ada1
dd if=/dev/zero of=/dev/ada2
dd if=/dev/zero of=/dev/ada3
