Steps to reproduce: 1) Have a floppy or other ridiculously small r/w media accessible on the sy= stem In this example, the floppy is /dev/da0. 2) Execute following commands to prepare media # gpart create -s gpt da0 da0 created # gpart add -t freebsd-zfs da0 da0p1 created # gpart show da0 =3D> 40 2800 da0 GPT (1.4M) 40 2800 1 freebsd-zfs (1.4M) 3) Attempt to create pool # zpool create floppytest /dev/da0p1 cannot create 'floppytest': no such pool or dataset --=20 You are receiving this mail because: You are the assignee for the bug.=
