求教，挂载硬盘到/home目录作为数据盘，这样算是成功了么？

# fdisk -lh
fdisk: invalid option -- h
Usage: fdisk [-b SSZ] [-u] DISK Change partition table
fdisk -l [-b SSZ] [-u] DISKList partition table(s)
fdisk -s PARTITION Give partition size(s) in blocks
fdisk -v Give fdisk version
Here DISK is something like /dev/hdb or /dev/sda
and PARTITION is something like /dev/hda7
-u: give Start and End in sector (instead of cylinder) units
-b 2048: (for certain MO disks) use 2048-byte sectors

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 2610.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

# 过程是没错，不过之前/home下的目录和文件是要在挂载前先拷出来的，挂载后在拷回去
回复 2# 的帖子
我的是重装系统之后挂载的，挂载了之后才安装lnmp0.9，这样需要复制出来么？谢谢军哥！ 只要下面没数据就不用复制出来
