我们mkfs在磁盘上执行sda以下操作
mkfs.ext4 -j -m 0 /dev/sda -F

实际上文件系统并未创建，我们可以从中看到lsblk -f
lsblk -f
NAME FSTYPE LABEL UUID MOUNTPOINT
sda
因此来自 mkfs 的警告是
Allocating group tables: done
Warning: could not read block 0: Attempt to read block from filesystem resulted in short read
Warning: could not erase sector 0: Attempt to write block to filesystem resulted in short write
Writing inode tables: done

是否有机会采取一些旁路或变通方法以便在sda磁盘上创建文件系统？
