As you have 3x nodes, you can simply do it one node at a time. Assuming you are using a size 3 / min_size 2 for your Ceph pools. No need to move any image.
Ceph OSDs are portable, meaning, if you configure the newly installed node to be connected (and configured) to the same Ceph cluster, the OSDs should just pop-in again. First deactivate HA on all nodes. Then you could try to clone the OS disk to the SSD (eg. clonezilla, dd). Or remove the node from the cluster (not from Ceph) and re-install it from scratch. Later on, the old SAS disk can be reused as additional OSD. -- Cheers, Alwin _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
