系统盘瓯子mirror，一块空间不足，另一块还有100+G？？？？？
做mirror的两块盘，hdisk0的FREE PPs为0，而hdisk1还有100多个G，目前是否需要迁移？如何操作，注意哪些事项？

发现是fslv03占用了大部分的hdisk0的空间，
查看lslv -m fslv03 发现，是这个lv在hdisk0是嘎巴发占了300多，在hdisk1上占了60+，
Df –g 查看，这个用的不是很多，所以先缩容，fslv03 80G，再给lv扩容80G，选定从hdisk1上加，
smitty lvm =>LV管理=>set... =>设置现有某LV属性，可以调整LV最大LP数限制
=>increase... =>扩容LV， 扩容时，新增LP后，总LP数不可超过LV最大LP数限制
之后扩fs，之后lspv hdisk0查看
