为什么我会收到“现有超级块读取失败：参数无效”

运行时遇到问题mfks.xfs -f -i

$truncate -s 41943040 /d/backends/disk1

$mkfs.xfs -f -i size=512 /d/backends/disk1

给出错误

答案1

您正在向 提供“挂载点”( /d/backends/disk1) mkfs.xfs。它需要一个设备（检查man mkfs.xfs), like/dev/sdq . Alsomkfs.xfs won't work on a mounted disk (/d/backends/disk1`）。

答案2

我已经构建并安装xfsprogs解决了我的问题

apt-get install libtool automake gettext libblkid-dev uuid-dev
git clone git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git
cd fsprogs-dev
make && make install
