操作大致如下：
# vgdisplay -v |more
查看vg00中是否还有剩余空间可供扩展swap用。剩余空间用PE-physical extents表示，每个PE都对应大小，可以用Free PE数量乘以PE大小算得。
#swapinfo -at
查看当前swap分区的信息。
#lvcreate -L 1024M -n myswap /dev/vg00
在vg00上创建大小为1G的lv，并命名为myswap。
#vi /etc/fstab
添加行：
/dev/vg00/myswap /myswap swap defaults 0 0
#swapon /dev/vg00/myswap
激活新添加的swap分区。
#swapinfo -at
确认新swap已经添加。
