Ceph » Orchestrator

Sequence of operations -
1) Boot strapped cluster using -

cephadm -v --image registry-proxy.engineering.redhat.com/rh-osbs/rhceph:ceph-5.0-rhel-8-containers-candidate-54312-20210519174049 bootstrap --mon-ip 10.8.129.101 --cluster-network 172.20.20.0/24

2) checked

cephadm shell ceph-volume inventory and
cephadm shell ceph orch device ls

To make sure that all three devices on host we listed as available

3) Created gpt labels on one of the devices using

parted /dev/sdd mklabel gpt

and checked

cephadm shell ceph-volume inventory and
cephadm shell ceph orch device ls

to make sure that the device with gpt label created was marked as not available.
'cephadm shell ceph orch device ls' had to be tried after intervals to see that changes updated (Did not know about --refresh)

4) Executed

ceph orch apply osd --all-available-devices  

And observed mgr logs

 sudo journalctl -fu ceph-d66b64e4-b923-11eb-ac53-0cc47a6ee150@mgr.pluto001.juyiug.service

and observed that device with gpt label was not excluded from the list of available devices and operation failed as ceph-volume fails to configure OSD on devices with GPT headers.
