steps::
# instance is located on A, B
- $ gnt-instance replace -n %nodeC% %instance1%
+ $ gnt-instance replace-disks -n %nodeC% %instance1%
# instance has moved from (A, B) to (A, C)
# we now flip the primary/secondary nodes
$ gnt-instance migrate %instance1%
# instance lives on (C, A)
# we can then change A to D via:
- $ gnt-instance replace -n %nodeD% %instance1%
+ $ gnt-instance replace-disks -n %nodeD% %instance1%
Which brings it into the final configuration of ``(C, D)``. Note that we
needed to do two replace-disks operation (two copies of the instance
The ``users-setup`` tool, when run, takes care of setting up the proper
users and groups.
-The tool does not accept any parameter, and requires root permissions to run.
+When invoked without parameters, the tool runs in interactive mode, showing the
+list of actions it will perform and asking for confirmation before proceeding.
+
+Providing the ``--yes-do-it`` parameter to the tool prevents the confirmation
+from being asked, and the users and groups will be created immediately.
