Thanks.
The old snapshots are being removed as the total never increases beyond 16, so when a new snapshot is added, the old one is removed.
immediatly removed, yes, but then Garbage collection takes place.
and perhaps with 19x16 GC to process it can't be done in one hour, and then next CR is launched, etc etc...
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.
