一把/data01扩容5G

二把datavg扩容16G

（1）查看vg

[root@localhost ~]# vgs
  VG       #PV #LV #SN Attr   VSize  VFree 
  datavg     4   2   0 wz--n- 63.97g 28.97g
  datavg02   1   1   0 wz--n- 31.97g 21.97g

（2）查看目录大小

[root@localhost ~]# df  -h  
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              45G 1004M   42G   3% /
tmpfs                 939M     0  939M   0% /dev/shm
/dev/sda1             772M   35M  698M   5% /boot
/dev/mapper/datavg-lvdata01
                       15G  141M   14G   1% /data01
/dev/mapper/datavg-lvdata02
                       20G   44M   19G   1% /data02
/dev/mapper/datavg02-lvdatavg0201
                      9.8G   23M  9.2G   1% /datavg

（3）查看lv

[root@localhost ~]# lvs 
  LV           VG       Attr       LSize  Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  lvdata01     datavg   -wi-ao---- 15.00g                                                    
  lvdata02     datavg   -wi-ao---- 20.00g                                                    
  lvdatavg0201 datavg02 -wi-ao---- 10.00g                                                    
[root@localhost ~]# lvdisplay
