A word of warning
Arch Linux is a distribution that by default runs the latest stable Linux kernel.
A major kernel update can break OpenZFS support until a newer version of OpenZFS is released.
It is recommended to run Arch Linux using the long-term support (LTS) Linux kernel.
LTS releases have a lower major version (still supported, stable and secure), which should always be supported by the current OpenZFS release.
Switching from the standard kernel to the LTS kernel is outside of the scope of this document.
This switch can be started by running something like
sudo pacman -S linux-lts linux-lts-headers, but remember that the system's boot loader might have to be adjusted to boot the LTS kernel instead of the regular kernel.
以下インストール過程を図示
USBで起動
と USBメモリは sda
ハードディスクは sdb
ということがわかる
したがって
次が重大
５〜１０分
とインストールは終了
電源ONして zfsなarchは立ち上がったが
ネットワークには つながってない。
そこで以下のようなことをした
例:
# ip link set enp5s0 up
# ip addr add 192.168.3.100/24 broadcast 192.168.3.255 dev enp5s0
もう一度
# ip link set enp5s0 up
してから
# ip route add default via 192.168.3.1
# echo 'nameserver 8.8.8.8' > /etc/resolv.conf
をして あとは`archlinuxをいつものように
インストすれば
となる
以下 alezを解析してみる
