Hi Larry, Congratulations. Your project proposal for: multiple disk sector size support Has received the needed number of core member votes. thanks Chuck -- This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
