  1. Vr2Io's post in Best way to move network config to new 10Gbps card was marked as the answer   
    No need, simple as put the 10G NIC be eth0 then fine.
     
    If you haven't local concole, you need 1G NIC for remote management in first.
  2. Vr2Io's post in Sharing ZFS on unraid: getting better performance was marked as the answer   
    I never try iSCSI or ZFS at Unraid, just notice some performance issue when access share through virtual network bridge, no matter array pool / RAID pool, passthrough a NIC have lot better performance.
  3. Vr2Io's post in unRAID System Log showing... kernel: ACPI BIOS ERROR (Solved) was marked as the answer   
    You could ignore those error.
  4. Vr2Io's post in External usb hard drives not spinning down + random spin ups was marked as the answer   
    Those are individual disk SMART setting to override global SMART setting.
    In "settings" -> "disk settings", you will found "Tunable (poll_attributes):" and global SMART setting too.
     

     
    BTW, it look like disk spin-up was due to USB-SATA bridge beehive not relate file access , those are hardware related ( also for Unraid can't read SMART ).
    I have some multi-bay USB enclosure, Unraid can read disk SMART and spindown ( but either enclosure disk spinup, all disk will spinup too ), different USB-SATA bridge will have different result.

  8. Vr2Io's post in Unriad Power OFF when add Parity Drive was marked as the answer   
    You have too much disk if all power by single PSU.
     
    I will try disconnect 2 disk power ( non array disk ) then add parity to check does power down or not.

    However, the QLC variant averaged USB 2.0-like speeds of just 40 MBps after the SLC cache was full.
     
    So slow write performance should be normal.
     

  11. Vr2Io's post in upgraded Hardware and now the Array will not start, Drive S/N changed was marked as the answer   
    In this case, preserve or not not much different for array, because s/n incorrect and you need to reassign.
