    md/unraid driver
    Introduced "multi-stream" support:

    Reads on devices which are not being written should run at full speed.  In addition, if you have set the md_write_method tunable to "reconstruct write", then while writing, if any read streams are detected, the write method is switched to "read/modifywrite".

    Parity sync/check should run at full speed by default.

    Parity sync/check is throttled back in presence of other active streams.

    The "stripe pool" resource is automatically shared evenly between all active streams.

    Should this work regardless of what network protocol is being used?

     

    I had parity check running and streaming a movie was completely impossible via NFS (I believe this was even possible without this feature before...).

    Haven't tried via SMB yet, just wondering whether if this feature protocol dependent or not.

    OK, I think I've got this figured out and it looks like this is caused by a race condition between detecting custom networks for dockers and the tips & tweak plugin applying "Disable NIC Flow Control" and "Disable NIC Offload".

     

    If I have tips & tweaks on default settings then custom networks are showing up for dockers, if I set the above two options to yes, then customer networks are not detected.

     

    Does this make any sense to you?

    While re-applying network settings helps, but after a reboot "custom : br0" disappears until I am re-applying network settings once again.

     

    So I need to re-apply network settings after each reboot for some reason to make custom nw available for dockers.

    Do you have an idea why is this? Shall I provide another diags?
