Bug Description

Vault appears to now support use of MySQL for HA storage:

  https://www.vaultproject.io/docs/configuration/storage/mysql.html#high-availability-parameters

This would avoid the need to use etcd in our deployments, and more importantly easyrsa which does not have HA in any meaningful way right now.

This may be the reason we did not use MySQL for HA:

As we direct all writes to a single node in the PXC cluster, using 'master' for pxc_strict_mode is probably OK and allows locking as required by vault.

I'm marking this as a duplicate of LP: #1883242 since the current plan is to leverage embedded raft storage in Vault instead of implementing etcd or mysql consolidated storage backend respectively.
