I'm a bit further than yesterday:
When I put back the OLD aes key into /etc/pve/priv/ceph/ceph.keyring my VMs can start!
With the new aes256k key in this file my VMs cannot start.
How can I proceed?
You are not alone, I'm having the same problem: https://forum.proxmox.com/threads/cephx-key-migration-procedure-and-ceph-19-2-squid-going-eol-soon.186276/post-869482
Dear all, I tried to migrate the keys like you described in the documentation. Unfortunately, I'm now stuck with an error, that a VM running on CEPH cannot start after shutdown due to the following error message:
