I have installed two-node clustered (Liberty) and running two VM's with flavors XLARGE and LARGE(both Ubuntu-14.04). As per the official document, the default size of the disk is 160GB and 80GB respectively for XLARGE and LARGE flavor.

But, df -h command is giving only 40GB disk space for both the VM's and we need more than 100GB for running our application.

I have not used cinder and swift volumes.

What may be the problem in this case ??

If this is the result of df on the instances (rather than the VM host), perhaps your flavours aren't standard? Did you check them (nova flavor-list)?

Also use qemu-img to double-check the size of storage files on the compute node(s).

Look for how much space Swap is using on the servers, I think rest of the space is consumed by Swap. its the default partitioning way of Ubuntu which might be causing this

I would suggest you to download trusty-server-cloudimg-amd64-disk1.img if you are on 64 bit architecture and retry.
