Hi everybody,

I'm using a Coraid storage with aoe driver, so every the disks images of 
the VMs are logical volumes as this :
# lvdisplay -C
   vm-300-disk-1 SAS -wi-ao 10.00G
   vm-101-disk-1 SATA  -wi-a- 32.00G

Inside my guest /dev/vdb is 10GB.

I'm testing the ability to extend partitions inside VMs, so i did a :
# lvextend -L+5g /dev/SAS/vm-300-disk-1
# lvdisplay -C
   vm-300-disk-1 SAS -wi-ao 15.00G
   vm-101-disk-1 SATA  -wi-a- 32.00G

When i'm testing this extending in the VM, i still have /dev/vdb with 

Is it possible to do that ?
What command i forgot to execute ??

Thank you
