we use the stats API in the engine, currently only to check if the backend is accessible, we have plans to use it for monitoring and validations but it is not implemented yet On Mon, Feb 24, 2020 at 3:35 PM Nir Soffer wrote: > > On Mon, Feb 24, 2020 at 3:03 PM Gorka Eguileor wrote: > > > > On 22

Thanks for the clarification on this. I've realised my mistake now - I need to configure the storage array to report the LUNs as larger than they physically are (to account for the expected de-dup ratio).  I was expecting oVirt to magaically know about this, which when thinking it through is not

I'm not really concerned about the reporting aspect, I can look in the storage vendor UI to see that. My concern is: will oVirt stop provisioning storage in the domain because it *thinks* the domain is full. De-dup is currently running at about 2.5:1 so I'm concerned that oVirt will think the do
