救援 fstab，安装我的磁盘 ext4 的参数无效

救援 fstab，安装我的磁盘 ext4 的参数无效

我遇到了一个问题，我认为我在 centos7 上编辑 /etc/fstab 时出现了错误，因此无法重新启动我的远程服务器。

我正处于 freebsd 的救援模式。

我无法挂载我的 ada0s3（在 centos 上是 sda3）来修复我的 fstab。

已尝试（谷歌上的一些解决方案）：

root@rescuefbsd:/mnt # mount -t ext4 /dev/ada0s3 /mnt
mount: /dev/ada0s3: Operation not supported by device

root@rescuefbsd:/mnt # mount /dev/ada0s3 /mnt
mount: /dev/ada0s3: Invalid argument

root@rescuefbsd:/mnt # mount -t ext2fs -o ro /dev/ada0s3 /mnt
mount: /dev/ada0s3: Invalid argument

请问有什么想法吗？

已解决，我的主机为我提供了支持 ext4 的 Rescue 3.0。
