I beileve to have seen the same issue. Mine was documented as: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6843555
Areca did issue a fixed firmware, but i can't say whether that indeed was the end of it, since we didn't do a controlled disk mixing experiment since then. I did find it strange that this is needed, since zfs is supposed imho to id the devices. However, I got an explanation from James McPherson about how the disk identification works, and it seems to reasonably explain why it will work with some controllers and not with others. I will ask James's permission to publish parts of his e-mail here. Hope he has no issue with that. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
