2. Saját gép maradt Debian 10.4-en, mert bevált.

"Out of the box" workaround nélkül látja a RAID1-met és eddig minden HW működik Nvidia kártya, stb. ebben a konfigban:

Az lvm2 tuti hibás! A softraides PV/VG/LV-ok nem mindig látszanak bootoláskor(próbáltam az /etc/lvm/lvm.conf fájlban a filteren állítani, de nem sokat segített).

Csúnya workaround:

1: Commenteld ki /etc/fstab-ban a sorokat:
h170pro4:/ # fgrep "#" /etc/fstab 
#/dev/raid1/home                            /home          xfs   noatime                       0  0

Ez a workaround mountol bootoláskor.

Miután az Ubuntu 18.04.3 Desktop (LTS-ben nem illik hibás telepítővel adni szerintem) telepítés közben kétszer is megállt, felraktam egy Debian 10.2-öt:

firmware-amd-graphics csomagot install https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/10.2.0+nonfree/amd64/iso-dvd/firmware-10.2.0-amd64-DVD-1.iso után kézzel telepíteni kellett Single modeban, NetworkManager indításával, ezt még szoknom kellett egy kicsit. Biztos ami ziher alapon nomodeset boot paraméterrel.

Szépen elmegy aludni a gép és vissza is jön alvásból(SSD-ről, eddig mindig viszajött).

Felokosítottam (non-free/contrib repok, Vulkan, Extra Codecek, Steam, AMD Tearing free lett stb.) a redszert minden jóval, megy rajta minden szépen a Steam is.

3 ingyenes játékot próbáltam:Dota Underlords(Vulkan), Battle Tanks, Tank Force azok mentek.

Még a végén attérek Debian 10.2-re OSS Leap 15.1-ről.

Itt is faék egyszerű a rescue mode, kipróbáltam, mint a Leap 15.1-en.

Elég jó lett.

A telepito hibakkal kuzkodik(nem kicsit).
2 SSD + 1 HDD kozul csak az elso SSD-be telepitette volna az OS-t.
Terminalban elkeszitettem neki a particiokat, PV-t, VG-t, LV-ket utana mar latta a telepito ezeket es telepitett is ra.
10 percnel kevesebb volt a telepites => SSD jo, nagyon jo.
A dmesg tele volt warningokkal(AMD driverek a ludasak), de a Superposition, glmarks2, glxgears latszolag szepen mukodott.
Van meg mit javitani az AMD-s drivereken+Mesan.

Ezt is az uj vasrol irom.
Kicsit megszenvedtem a szerelessel es az M$-os W10-es hibakkal, mire kiderult, hogy a regi HDD es/vagy az optikai meghajto a ludas.

0 hiba.
Atomstabil a rendszer!

Problema megoldva ezzel http://www.logilink.com/Products_LogiLink/Cable_Adapters/USB_30_Cable/U… .
Tobbet kajalna a WDC WD10JMVW-59AJGS4 USB 3.0-an, mint amit USB 3.0-an le tudna adni a ROCK64.
Innentol kezdve lehet folytatni a projektet.
DS3231 beallitva.
NFS es NTP serverek felkonfiguralva.
Raspberry Pi 3B funkciojat atveheti, ha nagyobb teszten atmegy a ROCK64! :)

Kernel module compilation:
Follow these instructions to compile an additional kernel module.
In this example, we’ll compile the ds1307 RTC kernel module for version 4.4.154-1124:
Obtain your kernel version: uname -r (ex: 4.4.154-1124-rockchip-ayufan-ged3ce4d15ec1)
Download the kernel source code which matches your kernel version from github.com/ayufan-rock64/linux-kernel/releases
Extract the kernel: tar -zxvf 4.4.154-1124-rockchip-ayufan.tar.gz
Copy the old kernel config: bash cd linux-kernel-4.4.154-1124-rockchip-ayufan cp /usr/src/linux
headers-4.4.154-1124-rockchip-ayufan-ged3ce4d15ec1/.config . make oldconfig
Install required build packages: apt-get install bc python libncurses5-dev
Configure the kernel with the additional modules you want: make menuconfig (ex: Device Drivers --> [*] Real Time
Clock --> Dallas/Maxim DS1307..)
Exit and save the config
Prepare the modules: ```bash make EXTRAVERSION=-1124-rockchip-ayufan-ged3ce4d15ec1 modules_prepare ````
Build the module: make M=drivers/rtc (note: specify the correct directory containing the module you added)
Copy the module to the modules directory: bash mkdir -p /lib/modules/4.4.154-1124-rockchip-ayufan
ged3ce4d15ec1/kernel/drivers/rtc/ cp drivers/rtc/rtc-ds1307.ko /lib/modules/4.4.154-1124-rockchip
ayufan-ged3ce4d15ec1/kernel/drivers/rtc/
Ensure module is added to dep file: bash echo 'kernel/drivers/rtc/rtc-ds1307.ko:' >> /lib/modules
4.4.154-1124-rockchip-ayufan-ged3ce4d15ec1/modules.dep
Load the module: bash depmod -a modprobe rtc-ds1307
Ensure module is loaded on boot: echo "rtc-ds1307" >> /etc/modules
