Trouble is that after some mkfs tools don't zero-out the signatures. In some cases the can be enough of FS remaining to even actually read some files. There is no way to easily distinguish which FS is a leftover and which is a real one. I recommend clearing signatures. It seems that zfs code has a bug, I'll look into it. -- Regards Vladimir 'φ-coder/phcoder' Serbinenko
