This is simlar situation to the most common problem with gmirror(8). When people decide to put their file system onto a mirror, it will eat partition's last sector, which isn't always safe. When disk is already partitioned and file systems are there, you cannot just take the last sector. > >I hope we don't play "convince phk@" game here. >=20 > In fact we do.

Most likely disk(9) KPI will be extended. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
