无法在带有分离标头的 luks 上的 lvm 上挂载 /sysroot - zfs

无法在带有分离标头的 luks 上的 lvm 上挂载 /sysroot - zfs

我尝试安装新系统。具有加密的 zfs 和分离的标头并在 USB 上启动。但我无法启动，因为 /sysroot 挂载失败。 systems boot log

我尝试更改内核参数和不同的挂钩。我无法进入紧急 shell，因为 root 似乎被锁定，尽管为 root 设置了密码。所以我只能通过 live iso 进行访问。

chroot 中的journalctl 回复没有日​​志。

这是我的设置：

ZFS坐骑

我有点困惑为什么

zfs mount

在 chroot 中为我显示不同的输出

zfs mount (in chroot)
rpool/ROOT/arch /

（直播系统中）

zfs mount (in live system)

rpool/ROOT/opt                  /mnt/opt
rpool/home/root                 /mnt/root
rpool/ROOT/var/log              /mnt/var/log
rpool/home                      /mnt/home
rpool/ROOT/var/lib/systemd/coredump  /mnt/var/lib/systemd/coredump
rpool/ROOT/usr/local            /mnt/usr/local
rpool/home/maksim               /mnt/home/maksim
rpool/ROOT/var/log/journal      /mnt/var/log/journal
rpool/ROOT/arch                 /mnt

我只是花了最后几个小时解决相同的错误，但设置了单个磁盘。也许这会有所帮助。

尝试在计算机上运行 LIVE USB/CD 并安装 EPS 分区。在那里检查loader/entries/arch.conf文件。我发现我有一个像root=PARTUUID=xxxxxxxx....我所要做的就是将其更改为root=/dev/mapper/<partition label>.这按预期工作了。希望有帮助。
