zpool upgrade broke GRUB Need to say that I have OpenSolaris on my Sony Vaio laptop. And I am following newest releases of OpenSolaris: 86, 96, 97 and now 98. In between builds 86 and 98 ZFS pool version was increased twice from 11 to 12 and from 12 to 13. I am paying attention to zfs status because I have external USB drive attached (Lacie 250GB) for mirror (backup) purposes. So I was doing zfs upgrade two times and two times had a problem with next boot. The problem is that GRUB is not able to see new ZFS and so it brings GRUB prompt. -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
