@henri9813 said in XOSTOR hyperconvergence preview: of course, i checked, my SR was not full The visual representation of used space is for informational purposes only; it's an approximation that takes into account replication, disks in use, etc. For more information: https://docs.xcp-ng.org/xostor/#how-a-linstor-sr-capacity-is-calculated We plan to display a complete view of each physical disk space on each host someday to provide a more detailed overview. In any case, if you use "lvs"/"vgs" on each machine, you should indeed see the actual disk space used.
