COPIES(008:000:000) 表示第一个物理卷上有8个物理分区，没有第二和第三的拷贝分区

IN BAND(75%) 表示center[6] / center[6] + inner middle[2] = 0.75

增加某个文件系统的空间

1. df -g | grep /home 查看/home所属的逻辑卷，假设是hd1

2. lslv -l hd1 查看hd1所属的物理卷，假设是hdisk0

3. lspv -p hdisk0 查看物理卷的可用空间

4. smitty chfs 或者 chfs -a size=+10G /home

5. 如果执行上述命令时出现问题:Maximum allocation for logical volume hd1，运行命令

chlv -x 800 hd1 或 smitty chlv 或 smitty lv
