Description Elad 2015-08-17 03:43:45 EDT 
Description of problem:
Tried to deploy hosted-engine over iSCSI using RHEVM-appliance. During the deployment, I was informed that the OVF does not contain a valid image description and that it will use the default one.
Then the setup failed with the following message that appeared endlessly:

2015-08-17 10:21:05 WARNING otopi.plugins.ovirt_hosted_engine_setup.vm.image image._disk_customization:124 Not enough free space, about 46 GiB are available

Version-Release number of selected component (if applicable):
ovirt-hosted-engine-setup-1.2.5.2-1.el7ev.noarch
vdsm-4.16.24-2.el7ev.x86_64

How reproducible:
While using RHEVM-appliance that doesn't have a valid image description 

Steps to Reproduce:
1. Deploy hosted-engine using RHEVM-appliance over a LUN exposed by iSCSI (51G LUN in my case)


Actual results:

2015-08-17 10:21:33 WARNING otopi.plugins.ovirt_hosted_engine_setup.vm.image image._disk_customization:124 Not enough free space, about 46 GiB are available

2 issues here:
1) Deployment failed with the mentioned message. The message says that there is not enough free space, about 46G are available. 46G should be enough for hosted-engine image.
2) The message was thrown endlessly.

Expected results:
Deployment using RHEVM-appliance using iSCSI should succeed while having 46G available in the used LUN. Also, the message should not appear endlessly.

This one was indeed correct: from the log I see that the appliance was sized for 50 GB
2015-08-17 10:20:08 DEBUG otopi.context context.dumpEnvironment:500 ENV OVEHOSTED_STORAGE/imgSizeGB=int:'50'

And the storage domain structures on a block device requires something less than 5 GB so the free space on a 51G LUN after the creation of an empty storage domain is just about 46 GB which is not enough to deploy a 50 GB large appliance.
Please see: https://bugzilla.redhat.com/1163088

> 2) The message was thrown endlessly.

Were you running it not interactively via answerfile?
On interactive setup it should loop letting you choose a different storage device while answerfile is always provinding the same answers and so the infinite loop.
We should detect it and raise breaking the loop.

I deployed interactively. I got this message infinitely, without the ability to answer it. It was thrown several times per second as you can see in the timestamps in the logs.

Ok, sorry: if you used an appliance it takes the image size from the OVF so, regarding this specific question, it's always not interactively.
The posted patch will solve as well.
Comment 6 Elad 2015-11-09 04:09:59 EST 
In case a LUN which its size is not sufficient for hosted-engine deployment using appliance is picked, the setup is aborted nicely and not enters to a loop.
