Do you have enough space in your volume group's backing file?

sudo pvdisplay | grep nova-volumes -n3 | grep Allocatable

What command are you issuing to create the volume, specifically, what zone are 
you passing?

 I tried creating from Dashboard as well as command, but both are not
 creating volumes.

 nova volume-create --display_name v1 2

  specifically, what zone are you passing?

 Please can you tell me what is a zone here, where to define and how to pass
 zone information ?

Hello Sashi,

Along with the zone info requested, would it be possible to get a look
at the nova-volume logs and possibly the nova-compute logs?  If you
look in these two places one of them is likely to contain some more
information that would help isolate the problem.

Thanks,
John
