what can i do about it ?
 
Most likely you run out of LVM snapshot space? You can increase snapshot size by setting the 'size' parameter in /etc/vzdump.conf.

See

# man vzdump
 
less /etc/vzdump.conf
# vzdump default settings

default we use 1 GB (1000) for LVM snapshot space. increase it, for example to 8 GB.

size: 80000

you have a total of 16 GB, so a snapshot can be up to 16 GB.
 
my VM's are more then 150GB size
what do you recommend my to do ?
if i understand i can't configure more then 16GN of LVM space
is there any way to re-size the LVM ?
