@carloum70 Yep I tested on XOA, latest version
You can use https://vates.tech/en/deploy/ to deploy the XOA, register for free and reimport your XO configuration
Different use cases: Ceph is better with more hosts (at least 6 or 7 minimum) while XOSTOR is better between 3 to 7/8.
We might have better Ceph support in the future for large clusters.
