  • 1.  is aborting of syncvg possible?

    Is there any "algorithm" to calculate performance degradation (if any) during such syncvg running?
    kind regards,

    Ok, I have tested it killing syncvg and lrsynclv processes and looks it works. The question is now if it is not recommended for any reasons? Risk of a data corruption?

    Depends how you killed it .. lrsynclv should clean up its current PP sync if you used a kill -15, but you will probably end up with a partially mirrored LV, which you do not want and is not much use, so you would have to clean up and re mirror .. if you ran with a kill -9 then you could end up with a partially mirrored PP and risk data corruption on the mirrored PP which could in a worst case scenario crash your system if you tried to read from that mirror ..

    So, in general, don't kill it ..
