[ceph-users] Find out num of PGs that would go offline on OSD shutdown

Hi all, Proxmox VE warns me if I want to shut down an OSD, and some PGs would go offline if I continue. In the warning it tells me the exact number of affected PGs. I have now searched a bit, but wasn't able to find out how Proxmox knows the exact number. How can that be done on the CLI? Thanks for some hints. -- Andre Tann
