我已经搜索了论坛，但找不到合适的答案：
我有一个Ubuntu Server 10.04作为KVM主机和一个来宾系统，该系统也运行10.04。主机系统使用LVM，共有三个逻辑卷，它们作为虚拟块设备提供给来宾-一个用于/，一个用于/ home和一个用于交换。来宾已分区，没有LVM。
我已经扩大了主机系统中的逻辑卷-来宾成功看到了更大的虚拟磁盘。但是，该虚拟磁盘包含一个“旧的”分区，该分区仍然具有旧的小尺寸。
fdisk -l的输出是

我想要实现的是简单地增加或调整分区/ dev / vdc1的大小，以便它使用虚拟块设备/ dev / vdc提供的整个空间。问题是，当我尝试分开时，它会抱怨：

WARNING: you are attempting to use parted to operate on (resize) a file system.
parted's file system manipulation code is not as robust as what you'll find in
dedicated, file-system-specific packages like e2fsprogs. We recommend
you use parted only to manipulate partition tables, whenever possible.
Support for performing most operations on most types of file systems
will be removed in an upcoming release.

那我该怎么办？这是一个无头生产系统。扩展此分区的安全方法是什么？不过，我可以卸下它-因此这不是问题。
编辑：Cfdisk显示了一个小的可用空间的未分区空间，然后是分区（标记为“ boot”和Linux / ext3），然后是其余的未分区空间。删除分区并使用cfdisk再次创建分区后-cfdisk显示了一个大分区区域（这对我来说很好），并且作为文件系统类型，仅“ Linux”
