→ OrzOGC:fstab先改成/dev/sdx之類的.你的label亂掉了
→ OrzOGC:基本上重灌是不會動到/home之下的東西
我先fdisk -l /dev/sda之後

顯示的磁碟訊息是這樣

[root@localhost /]# fdisk -l /dev/sda

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1         131     1052226   83  Linux
/dev/sda2             132       16704   133122622+  83  Linux
/dev/sda3           16705       19315    20972857+  83  Linux
/dev/sda4           19316       19457     1140615    5  Extended
/dev/sda5           19316       19457     1140583+  82  Linux swap / Solaris

[root@localhost /]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              20G   12G  7.3G  61% /
/dev/sda1             996M   39M  906M   5% /boot
/dev/sda2             123G  105G   13G  90% /home

所以我可以確定sda1是/boot，sda2是/home，/sda3是/

而且swap是sda5

所以我直接把fstab的最後一行改成

LABEL=/                 /                     ext3    defaults        1 1
LABEL=/boot             /boot                 ext3    defaults        1 2
devpts                  /dev/pts              devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm              tmpfs   defaults        0 0
LABEL=/home             /home                 ext3    defaults        1 2
proc                    /proc                 proc    defaults        0 0
sysfs                   /sys                  sysfs   defaults        0 0
/dev/sda5                swap                 swap    defaults        0 0

再來做mkswap的動作，並swapon

參考：http://linuxpoison.blogspot.com/2008/03/mkswap-swapon-and-swapoff.html

[root@localhost /]# mkswap -c /dev/sda5
Setting up swapspace version 1, size = 1167949 kB
[root@localhost /]# swapon /dev/sda5
swapon: /dev/sda5: Device or resource busy
[root@localhost /]# swapoff /dev/sda5
[root@localhost /]# swapon /dev/sda5

然後重開機

錯誤訊息還是如同之前一樣

Unable to acess resume device (LABEL=SWAP-sda5)
mount: could not find file system '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
kernel panic - not syncing: Attempted to kill init!-d000

請問O大的意思是我應該利用e2label把每一個磁區都LABEL起來

然後把fstab都改成LABEL=/{LABEL_name}   /{mountpoint}這樣嗎？

還是說我應該直接用/dev/sdaX   /{mountpoint}

推 ago1414:先把最後一行 註解  再用 fdisk -l /dev/sda 哪個是swap

多謝幫助:P
