BTRFS安装不可能

Question

嘿，在更新期间冻结后，我的btrfs分区无法挂载。我试过从Archlinux和BTRFS中找到所有的东西，但这还不够。

我的尝试和输出：

$ sudo -t btrfs /dev/sda3 3 /mnt

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda3, missing codepage or helper program, or other error.

我想你可以试试这个

sudo mount -o noatime,commit=120,compress=zstd,space_cache=v2,discard=async,subvol=@ /dev/sda2 /mnt

将您的子卷名称更改为您要挂载的实际子卷。@ is /，而根下的任何其他挂载点，例如/home是@home等等。您可以忽略大多数挂载选项，但subvol是必要的。
