Rekeying vault in a raft HA configuration only rekeys the current node. For example, if I have vault1, vault2, and vault3, I can connect to vault1 and rekey it, but vault2 and vault3 still use the old unseal keys. If I were to now connect to vault2 and vault3 and rotate them individually, I now have 3 different sets of unseal keys to manage.
Ideally, when I rotate one node, all the other nodes will also be rotated so I have one set of unseal keys to manage all of them. Is there any way to do this currently? If not, is there anything planned?
