增加LV swap分区大小

1、 关闭交换分区

[root@ts01 ~]# free
             total       used       free     shared    buffers     cached
Mem:     267269056   13625040  253644016          0     323824    5051312
-/+ buffers/cache:    8249904  259019152
Swap:     10354656          0   10354656
[root@ts01 ~]# swapoff /dev/VolGroup00/LogVol01
[root@ts01 ~]# free -m
             total       used       free     shared    buffers     cached
Mem:        261004      13305     247699          0        316       4932
-/+ buffers/cache:       8056     252948
Swap:            0          0          0

2、扩展   /dev/VolGroup00/LogVol01，增加70GB

 [root@ts01 ~]# lvextend -L +70G /dev/VolGroup00/LogVol01
  Extending logical volume LogVol01 to 79.88 GB
  Logical volume LogVol01 successfully resized

3、将 /dev/VolGroup/lv_swap设置为swap分区

 [root@ts01 ~]# mkswap /dev/VolGroup00/LogVol01
Setting up swapspace version 1, size = 85765111 kB

 4、启动swap分区

[root@ts01 ~]# swapon /dev/VolGroup00/LogVol01

[root@ts01 ~]# free
             total       used       free     shared    buffers     cached
