I finally got to test the system and these are the diagnostics , outside of the BTRFS raid reporting different usage sizes, everything else looks normal clean-boot-diagnostics-20190308-1925.zip after-size-reduction-diagnostics-20190309-1901.zip

Good afternoon, I did some searching around the forum, but couldnt find anything that fit my situation and was looking for some insight. I have a RAID10 cache pool with 4x 250GB SSDs. The setup is really new so there's not much on it yet. THe following shares are set to "Prefer": appdata, domain, and system. Docker and VMs are enabled, with both the Docker and VirtIO img files being shown as residing on the Cache. When the Unraid server has just booting up and the Array has been started the Cache shows that 25.0GBs are in use (see the image named cache-refresh-reboot) im, which is normal. It contains the Docker img (20GB), libvirt img(1.07GB) and Krusader docker data. However, after the system has been on for some time and I do file copies in Krusader, the cache seems to report only 7GBs of space being used (see image named cache-after-krusader-launch) Only thing I've seen that is short of related is that if you use different sized SSDs , then the amount is under reported (see this link Changing Cache Raid Mode ). But all mine are the same size SSDs. Any insight? Has anyone else seen this behavior before?

I would recommend leaving some threads for UnRaid.

I agree with jonathanm, you might want to check the USB drive you used. I recently went from an older AMD (non-FX) cpu and motherboard to an Intel Coffee Lake CPU and motherboard; everything came up just fine. Just moved over the hardware and usb drive. Also, you should be able to check all your hard drives are OK using an external USB drive and another Linux machine. Someone else in the forum can correct me if this is wrong. But you should be able to just mount the non-parity drives and see if the data is still intact and the drive works. Also, are your SAS controllers ok? I know on newer motherboards with UEFI BIOS (even though the compatibility mode is turned on in the motherboard's BIOS) HBA cards can take a long to boot unless you disable the BIOS on the SAS card themselves and maybe something is timing out in the process? See link: LSI-9211 boots extremely slow I don't think you're completely out of luck. If you can't bring up the original array, your data drives are all OK and you have at least one or two empty data drives, you could do the following: Create a new array with the two parity drives and one or two of the empty data hard drives After the parity sync completes, setup your shares again Take one full hard drive and copy the data back to the array (either through your network shares or attaching the hard drive to the unRaid server via USB and the unassigned devices plugin with the Krusader docker container) Once the full hard drive has all of its contents copied to the array, you can add the now empty drive to the array Repeat steps 3 and 4 until all the drives are back into the array

Notifications regarding Unraid OS updates haven't been removed as far as I know. I did receive the notification, but it wasn't until a couple weeks later after the OS announcements were officially announced.

I think this depends on the type of games your sons play. Simpler games , VM with 4 vcpus (or threads) and 8GBs of RAM might do the trick. Higher end games , you might need a more resources. Also, you didn't specify if you have any video hardware to passthru to the VMs, which would help in gaming.

I have an unraid server (6.6.0) with the following hardware: ASRock - H370M-ITX/ac Pentium G5400 CPU @ 3.7ghz 8GB DDR4 RAM LSI HBA Host Bus Adapter 9211-8i (hard drives are connected to this card) 4 - 8TB Western Digital RED drives Intel I219-V gigabit nic This is my first NAS server setup, I was wondering, when I copy data off the Unraid server to my Windows 10 desktop (on the same gigabit switch), I see the CPU usage hover between 50 - 70% (as seen in the attached screenshot) for large file copies. Is that normal? Do I need a better CPU? Nothing else is happening on the server, i dont use Docker or VMs. My desktop has an intel nic as well, all MTU settings are the default 1500. I've searched the forums and couldn't find any info, with the exception of people having high CPU usage when not using a HBA adapter. Any advice or info is definitely appreciated.
