嘿，在更新期间冻结后，我的btrfs分区无法安装。我尝试了我能找到的Archlinux和Btrfs Wiki的所有方法，但这还不够。
我尝试的内容和输出：
$ sudo Mount -t btrfs/dev/sda3/mnt

我想您可以尝试以下操作：
sudo mount -o noatime,commit=120,compress=zstd,space_cache=v2,discard=async,subvol=@ /dev/sda2 /mnt
将您的子批量名称更改为您要安装的实际子体积。@ is/，而root下的任何其他安装点，例如/home是@home等。您可以忽略大多数安装选项，但是subvol是必要的。
