On Hi Cephers, I'm building a new Squid cluster with cephadm on Ubuntu 24.04. After expanding my cluster in the Dashboard (adding my 7 hosts), I choose throughput_optimized proflie wich create a generic spec for hybrid HDD/SSD : service_type: osd service_id: throughput_optimized service_name: osd.throughput_optimized placement: host_pattern: '*' spec: data_devices: rotational: 1 db_devices: rotational: 0 encrypted: true filter_logic: AND objectstore: bluestore The cluster is for a LAB environment, on each of the 7 nodes, I have 17 HDD SAS 1.2TB drives and 1 SSD SAS Enterprise 400GB drive. On my first try, only 28 OSD where created (out of the 119), the others appeared as down, but they won't start, I didn't find systemd units created on the hosts. But, the VGs and LVs where created, there are 17 LVs on the SSD for WAL/DB of the 17 HDD (yes, small : 29GB). On my second try, it creates 72 OSDs, still it stops, and never tries to continue, or re-create the down OSDs. I didn't manage to find them, but it seems I saw some OSD creation timeout in the logs... What can I do to have my missing OSD created ? I tried restarting, redeploying the orch OSD service, but it only restart/redeploy le OSDs it has already created...
