Public bug reported: My question is the following (maybe a feature request, I do no how to create one) :
Imagine a service like GlusterFS requiring to migrate data from removed bricks before shuting-down the node(s) that will be removed from the cluster. gluster/0 with volume1 gluster/1 with volume2 (replica=2) gluster/2 with volume2 (replica=2) How exactly juju triggers the hooks of the units of that service ? I imagine that all units are aware of the departure of gluster/2 if we remove gluster/2. A good feature will be to have, as user, a way to express our desire to scale-down the service without specifying one particular unit, unlike juju remove-unit. Another will be, as unit of the service, a way to "decide" to cancel or warn the user helped by juju. For example, if the user uses juju remove- unit gluster/0 it will loose all data of volume1 !
