Health Warn OSD count 0 < osd_pool_default_size 3 of my Proxmox Virtual Environment 6.1-3

[leehyalbert]

I am new and less knowledge of Virtual Environment 6.1-3. I already handover our company's Virtual Environment 6.1-3 which created by our ex Senior Engineer.

Today I login the Proxmox and check the status in "Ceph" tab. I discover the Health Warn as the subject.

Please help give some advice to me to solved the above issue.

Thanks.

You do not have OSDs in your cluster for one or all pools. Use ceph osd tree to verify that.

And a good point to start delving into Ceph.
