@olivierlambert I agree. But just thought I should report nevertheless.

Hello, I plan to install my XOSTOR cluster on a pool of 7 nodes with 3 replicas, but not all nodes at once because disks are in use. consider: node1 node2 node ... node 5 node 6 node 7. with 2 disks on each sda: 128GB for the OS sdb: 1TB for local sr ( for now ) I emptied node 6 & 7. so, here is what i plan to do: On ALL NODES: setup linstor packages Run the install script on node 6 & 7 to add their disks so: node6# install.sh --disks /dev/sdb node7# install.sh --disks /dev/sdb Then, configure the SR and the linstor plugin manager as the following xe sr-create \ type=linstor name-label=pool-01 \ host-uuid=XXXX \ device-config:group-name=linstor_group/thin_device device-config:redundancy=3 shared=true device-config:provisioning=thin Normally, i should have a linstor cluster running of 2 nodes ( 2 satellite and one controller randomly placed ) with only 2 disks and then, only 2/3 working replicas. The cluster SHOULD be usable ( i'm right on this point ? ) The next step, would be to move VM from node 5 on it to evacuate node 5. and then add it to the cluster by the following node5# install.sh --disks /dev/sdb node5# xe host-call-plugin \ host-uuid=node5-uuid \ plugin=linstor-manager \ fn=addHost args:groupName=linstor_group/thin_device That should deploy satelite on node 5 and add the disk. I normally should have 3/3 working replicas and can start to deploy others nodes progressively. I'm right on the process ? aS mentionned in the discord, i will post my feedbacks and results from my setup once i finalized it. ( maybe thought a blog post somewhere ). Thanks to provide xostor in opensource, it's clearly the missing piece for this virtualization stack in opensource ( vs proxmox )
