The usage of ``cluster-merge`` is as follows::
- cluster-merge [--debug|--verbose] [--watcher-pause-period SECONDS] <cluster> \
- <cluster...>
+ cluster-merge [--debug|--verbose] [--watcher-pause-period SECONDS] \
+ [--groups [merge|rename]] <cluster> [<cluster...>]
You can provide multiple clusters. The tool will then go over every
cluster in serial and perform the steps to merge it into the invoking
``--watcher-pause-period``
Define the period of time in seconds the watcher shall be disabled,
default is 1800 seconds (30 minutes).
+``--groups``
+ This option controls how ``cluster-merge`` handles duplicate node
+ group names on the merging clusters. If ``merge`` is specified then
+ all node groups with the same name will be merged into one. If
+ ``rename`` is specified, then conflicting node groups on the remove
+ clusters will have their cluster name appended to the group name. If
+ this option is not speicifed, then ``cluster-merge`` will refuse to
+ continue if it finds conflicting group names, otherwise it will
+ proceed as normal.
