新买了一个500G的硬盘，今天终于拿到了。
开始将Gentoo移到新的硬盘上去。
先是分区：fdisk /dev/sdb
gentoo-pjq pjq # fdisk -l /dev/sdb
Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xf265e339
Device Boot Start End Blocks Id System
/dev/sdb1 1 26 208813+ 83 Linux
/dev/sdb2 27 60801 488175187+ 5 Extended
/dev/sdb5 27 549 4200966 83 Linux
/dev/sdb6 550 7077 52436128+ 83 Linux
/dev/sdb7 7078 13605 52436128+ 83 Linux
/dev/sdb1 200M 挂载到/boot
/dev/sdb5 4G 挂载到swap
/dev/sdb6 50G 挂载到/
/dev/sdb7 50G 挂载到/home
分好区后用mke2fs进行文件系统格式化：
mke2fs /dev/sdb1
mkswap /dev/sdb5
mke2fs -j /dev/sdb6
mke2fs -j /dev/sdb7
格式化完后，将它们挂载:
mount /dev/sdb1 /media/sdb1
mount /dev/sdb6 /media/sdb6
mount /dev/sdb7 /media/sdb7
然后进行手动拷贝：
cp /boot/* /media/sdb1/ -a
cp /home/* /media/sdb7/ -a
然后是根目录copy了：
由于根目录下已经有了/boot,/home/,/media
所以只好将根目录下的文件夹一个个手动拷贝了。
完了之后在建立相关的目录：
mkdir /media/sdb6/{home,boot,media}
目录建好了后，
就是修改相关的引导文件了，一个是menu.lst,一个是fstab,
gentoo-pjq pjq # cat /boot/grub/menu.lst
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
#gfxmenu (hd0,10)/boot/message.cristal
#splashimage=(hd1,0)/boot/grub/splash.xpm.gz
default 0
timeout 4

kernel /boot/kernel-2.6.30-r6 root=/dev/sdb6 plash=silent,fadein,theme:gentoo vga=792 CONSOLE=/dev/tty1 ramdisk=8192
boot
gentoo-pjq pjq # cat /etc/fstab
# /etc/fstab: static file system information.

# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.

说明一下：
title Gentoo-2.6.30-r6
root (hd0,0)
kernel /boot/kernel-2.6.30-r6 root=/dev/sdb6 plash=silent,fadein,theme:gentoo vga=792 CONSOLE=/dev/tty1 ramdisk=8192
boot
我一直以为要用root (hd1,0),但试过后都没用，试了几次终于成功了，但奇怪的是root=/dev/sdb6 却不是：
root=/dev/sda6.
在fstab中用的也是sdb,而不是sda,试了好几次终于试成功了。
还好，整个过程没有遇到什么问题，现在顺利的拷贝到新的硬盘上了，以后就不需要担心空间不够了。
现在看起来整个系统复杂多了：
gentoo-pjq pjq # mount

/dev/root on / type ext3 (rw,noatime,errors=continue,data=writeback)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)

/media/sda7/games on /var/www/localhost/htdocs/ftp/games type none (rw,bind)
/media/sda6/var on /var/www/localhost/htdocs/ftp/var type none (rw,bind)
但仔细看一下还是比较简单的。
现在新硬盘只用了100G，还有大约360G，想一下该怎么分呢，再分60给linux,其它的为NTFS和XP共用。
成功将Gentoo移到新买的硬盘上去
