    zfs_arc_max realtime

    Well, if you want to decrease your ARC, you need to free the already allocated memory. https://linux-mm.org/Drop_Caches Running that drop_caches command _should_ free the reclaimable RAM from the ARC. There are some deficiencies in the ZFS on Linux memory management though, which could cause...

    IO Delay

    I guess it's the use of swap, but if you want a proper analysis, you should give much more information. We're out of crystal balls, you know?

    zfs_arc_max realtime

    Ehm, you can w/o reboot by: echo "your wanted size in byte" > /sys/module/zfs/parameters/zfs_arc_max and a echo 3 > /proc/sys/vm/drop_caches

    Ballooning not working on windows KVM

    Is it possible to throttle backup and restore disk io?

    Edit, some more test and results: After this the arc was never beeing increased over arc_min_size, so after it was dropped during vzdump it was limited to 1.47G (=arc_min) instead of the full 7G until I did a reboot. Then I have set arc_min == arc_max and recognized that during a vzdump the arc...

    Is it possible to throttle backup and restore disk io?

    Oh, so this was "only" related to backup jobs. I have a machine with two storage pools, one for root and multiple VMs and one fast for only one VM, I recognized while rootpool is "under heavy load" the VM with its own storage has some freezes. So will my only option to avoid this be to get an...

    4.15 based test kernel for PVE 5.x available

    So even with 4.15.10-1-pve cpu type host is not working for Zen. Windows bootup is starting, but then after a while the VM eats 800-1400% CPU in top and nothing more is happening. Also I recognized that you can not passthrough the CPU internal USB controller to a VM anymore, which was working...
