PV resize

1. 查詢 VG vvv 時出現 PV size 警告訊息，必須 PV resize。
   

   [root@kvm5 ~]# vgdisplay vvv 
     WARNING: Device /dev/vda6 has size of 378880 sectors which is smaller than corresponding 
     PV size of 460800 sectors. Was device resized?
     One or more devices used as PVs in VG vvv have changed sizes.

2. /dev/vda6 做 PV resize。
   

   [root@kvm5 ~]# pvresize /dev/vda6
     WARNING: Device /dev/vda6 has size of 378880 sectors which is smaller than corresponding PV size of 460800 sectors. Was device resized?
     One or more devices used as PVs in VG vvv have changed sizes.
     Physical volume "/dev/vda6" changed
     1 physical volume(s) resized / 0 physical volume(s) not resized
   

3. 再查詢 VG vvv 時沒有警告訊息了。
   

   [root@kvm5 ~]# vgdisplay vvv
