rebootstrap-raft creates an empty raft cluster directory with server
configuration based on the current replicaset members. It's intended as
an emergency utility to resolve situations where the raft store has been
corrupted somehow.
For safety, it won't overwrite raft data—any existing raft directory
/var/lib/juju/raft will need to be removed or renamed. The new raft
directory won't have any lease information in it, but if the Juju
controller is part of an HA cluster and the other nodes still have lease
information, it will be replicated to this one when the controller agent
is started.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install rebootstrap-raft, simply use the following command:
sudo snap install rebootstrap-raft
Browse and find snaps from the convenience of your desktop using the snap store snap.
