[ceph-users] Encrypt OSDs on running System. A good Idea?

Hello all :-), We use Ceph both as storage in Proxmox and as storage in K8S. I would like to encrypt the OSDs. I have backups of the Proxmox machines, but honestly, I would prefer not to have to use them, as it would take two days to rebuild everything from scratch. I ran some tests on a small Proxmox machine, and telling the OSDs to encrypt themselves doesn’t seem too difficult. However, nothing is running on that storage. What issues should I expect if I take an OSD (15TB) out one at a time, encrypt it, and put it back into the cluster? I would have a long period where some OSDs are encrypted and others are not. How dangerous is this? Has anyone done it before ? Best wishes, Gio
