enable-ha command does not work with placement directive --to

[Pedro Guimarães]

Juju 2.6.3 (snap / stable channel)

Deployed a manual controller provider and added machines to controller model with:

juju add-machine -m controller ssh:ubuntu@A.B.C.D
Machine added got serial code 1

Then, ran enable-ha on this controller with:

juju enable-ha -n 1 --to 1 (added machine code)

Machine 1 was successfully added to controller model and I can see jujud-machine-1.service is running correctly.
However, there is no evidence of a controller was deployed on this node after enable-ha (e.g. no juju-db.service is present or telnet to localhost:17070 is refused).

Therefore, I see no way to run manual provider controller on ha mode.

Bug: https://bugs.launchpad.net/juju/+bug/1357760 is similar to this issue, however I am using command and placement directive described on "juju enable-ha --help" to try to get my controller to ha mode.

I've just tested juju from edge channel and it is working.
The way to run it is:

juju add-machine ... --> create machines 1 and 2 on model controller
juju enable-ha --to=1,2

According to rick_h, this merge is the one responsible for the new feature: https://github.com/juju/juju/pull/10185
