StarlingX 3.0 Only 150 GB space left for Hypervisor

[ANIRUDH GUPTA]

Brief Description
-----------------
Setup: I am trying to deploy Bare Metal StarlingX R2 duplex mode on Release 3.0.
On Each Server, I have 2 physical hard disk of 500 GB each (sda and sdb)
The entire sdb disk is used to Add an OSD on controller-0 for Ceph.

Out of the 500 GB available for the ROOT Disk, after successfull Bootstrapping, we are only left with ~150 GB only which could be used by the Hypervisor to create VMs.
The document suggests to set NOVA_SIZE=34, which would not even create 2 m1.small flavor VM

If we give the entire 150 GB available with us, then we can create only 7 VMs with m1.small flavor(20 GB Hard disk each to VM)

So technically out of 1000 GB, we are only able to utilize at max of 150 GB for the VM creation.

Is there any way to increase the space available for VM Creation

Severity
--------
Major

Expected Behavior
------------------
StarlingX should provide a way in which more Hard disk can be utilized by the Hypervisor to craete VM.

Actual Behavior
----------------
Only 150 GB out of 1 TB is available to the hypervisor for the VM Creation

Reproducibility
---------------
Everytime

System Configuration
--------------------
Two node system

To answer your question:
> Is there any way to increase the space available for VM Creation

Yes - you can use a larger disk. The starlingx platform allocates disk space on the root disk for various platform functions - you can see the allocated space with:
fdisk -l /dev/sda (or whatever your root disk is named)
lvs (to see the logical volumes in the Linux LVM partition)

We don't have any plans to reduce the disk space required by the platform. The 500 GB disk is the minimum recommended disk size - you are free to use a larger disk.

Marking as Won't Fix. As noted above, there are no plans to reduce the disk space required by the platform.
