If you are specifying an absolute number (i.e. it's not a percentage) as the offset then I don't think offset_align will fix it up for you - you asked explicitly for that offset: "offset_align=int If set to non-zero value, the byte offset generated by a percentage offset is aligned upwards to this value." -- Sitsofe | http://sucs.org/~sits/ -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
