Environment

SUSE OpenStack Cloud 8

Situation

Running the ardana command site.yml to set up cloud nodes failes with following error messages:

2019-03-19 10:02:47,818 p=25583 u=ardana |  failed: [ardana-cp1-c1-m3] => (item=({'physical_volumes': 
['/dev/sda_root'], 'consumer': {'name': 'os'}, 'name': 'ardana-vg'}, {'mount': '/', 'fstype': 'ext4', 
'name': 'root', 'size': '20%'})) => {"failed": true, "item": [{"consumer": {"name": "os"}, "name": 
"ardana-vg", "physical_volumes": ["/dev/sda_root"]}, {"fstype": "ext4", "mount": "/", "name": "root", 
"size": "20%"}]}

Resolution

Increasing the given disk size or change the percentage in disk model accordingly.

Example:

Given disk size is 295gb

percentage in your disk model for the logical root volume is 10%

the resulting/calculated volume size is below 30gb as it was created running bm-reimage.yml.

Cause

The logical volume "root" usually has a size about 30gb. But within the disk model the percentage

given will generate a size lower than 30gb if disk size is too small. Shrinking isn't supported.
