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
