Update: I tested same hard drives on different servers, and the sata hard drives do show up with command: ceph orch device ls The working systems are Intel pci v3 using chipset SATA controller. The systems not working are AMD pci v5 using chipset SATA controller. Both systems are running the same software image, kernel and ahci kernel module. Once I narrow this down, I will update post. cb From: Chris Brown <dogatemyiphone(a)gmail.com> Sent: Tuesday, February 28, 2023 1:16 PM To: ceph-users(a)ceph.io Subject: ceph quincy nvme drives displayed in device list sata ssd not displayed Hello, Setting up first ceph cluster in lab. Rocky 8.6 Ceph quincy Using curl install method Following cephadm deployment steps Everything works as expected except ceph orch device ls --refresh Only displays nvme devices and not the sata ssds on the ceph host. Tried sgdisk --zap-all /dev/sda wipefs -a /dev/sda Adding sata osd manually I get: ceph orch daemon add osd ceph-a:data_devices=/dev/sda Created no osd(s) on host ceph-a; already created? nvme osd gets added without issue. I have looked in the volume log on the node and monitor log on the admin server and have not seen anything that seems like an obvious clue. I can see commands running successfully against /dev/sda in the logs. Ideas? Thanks, cb
