Aleksandar Ivanisevic <[email protected]> writes:http://wiki.openvz.org/I/O_priorities_for_containers What priority is the host node? How do those priorities relate to ionice's priorities? My empirical research showed that even idle priority disk intensive task in a HN saturates a IOPRIO=7 container. Is that right?As far as i know the IOPRIO is only relevant for the container not for the HN because the HN does all IO for the containers so there is no useful setting for the HN anyway.I know that there is no setting, but what would be the I/O priority of the processes started in HN (VEID=0) in relation to the process started in VEID>0?
You should not start any "worker" process at the HN. The IO at the HN is not subject to any rate limit from the OpenVZ tools as far as i know. The IOPRIO for the container is used as relative value to divide the IO not consumed by the HN itself to the containers.
