阿里云 挂载数据盘出现问题

用 fdisk 弄了个盘 extended (container for logical partitions)

然后 mkfs.ext4 /dev/vdb1

提示

mkfs.ext4: inode_size (128) * inodes_count (0) too big for a
	filesystem with 0 blocks, specify higher inode_ratio (-i)
	or lower inode count (-N).

有人说要把原来的分区干掉, 我删不掉

No partition is defined yet!
Could not delete partition 1
