Thank you for your prompt response, Dear Anthony. I have fixed the problem. As I had already removed all the OSDs from my third node, this time I removed the ceph-node3 node from my Ceph Cluster. Then I re-added it as a new cluster node. I followed the following method: ceph osd crush remove ceph-node3 ceph orch host drain ceph-node3 After the node has been drained of all its services ceph orch host rm ceph-node3 --offline --force ceph orch apply osd --all-available-devices --unmanaged=false Then I logged into the ceph-node3 and disabled and removed all Ceph-related services. Removed all Ceph-related docker images and removed all Ceph-related directories in the OS filesystem, notably /etc/ceph, /var/lib/ceph/ and /var/log/ceph. Then I went back to ceph-node1 where the cephadm orchestrator was installed and added the ceph-node3 again into the Ceph Cluster. ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph-node3 ceph orch host add ceph-node3 10.10.10.13 Thus the node was re-added to the cluster, this time all the non-RAID hard drives were automatically added as OSD, and the Cluster was returning to normal state. Currently, the degraded PGs are recovering, Thank you > Anthony D'Atri wrote: > You probably have the H330 HBA, rebadged LSI. You can set the “mode” or “personality” > using storcli / perccli. You might need to remove the VDs from them too. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
