# 将分区转换成交换分区
#1、格式化交换分区［mkswap］
[root@localhost /]# mkswap /dev/sda5 
Setting up swapspace version 1, size = 106889 kB
[root@localhost /]# free
             total       used       free     shared    buffers     cached
Mem:       1026816     577392     449424          0      29772     343960
-/+ buffers/cache:     203660     823156
Swap:      2064344          0    2064344

#2、激活交换分区［swapon］
[root@localhost /]# swapon /dev/sda5 
[root@localhost /]# free
             total       used       free     shared    buffers     cached
Mem:       1026816     577448     449368          0      29792     343960
-/+ buffers/cache:     203696     823120
Swap:      2168724          0    2168724
[root@localhost /]# 

# 将交换分区转换成EXT3格式
#1、关闭交换分区［swapoff］
[root@localhost ~]# swapoff /dev/sda5

#2、重新格式化分区[mkfs.ext3]
[root@localhost ~]# mkfs.ext3 /dev/sda5
