Hi, using "Debian GNU/kFreeBSD 7.2.0 _Wheezy_ DVD-1 20131012-20:22" on 4x 2TB drive amd64 system. I'm using the expert install with kernel 9 and installing kernel 9.0.2 on the target. The Installation of GRUB on /dev/ada0 works on 4x 2TB ZFS stripe. But GRUB installation failes on ZRAID2 with 1 logical volume tank/root mounted as /: > Install GRUB to the master boot record: <Yes> > Unable to install GRUB in /dev/ada0 Regards, Klaus -- kmel@gmx.de
