** [tickets:#1235] NodeGroup shutdown Admin op to support parallel admin
shutdown and admin lock on multiple nodes**
**Status:** fixed
**Milestone:** 4.6.FC
**Created:** Wed Dec 10, 2014 12:25 PM UTC by Mathi Naickan
**Last Updated:** Mon Mar 02, 2015 01:40 PM UTC
**Owner:** Praveen
Today, it is not possible to initiate AMF node shutdown operation on multiple
nodes at the same time.
This ticket proposes (praveen's idea) to introduce a new AMF admin operation on
the nodegroup logical entity.
A cluter scale-down usecase might introduce limits on the total time spent in
down-sizing an AMF/application cluster. This enhancement shall look into
different ways by which atleast some amount of parallelism is induced/pushing
within AMF (wherever applicable) during the processing of this new 'node-group'
shutdown operation.
End of the day, the final timetake will be a mix of
1) amount of time spent in the checks inside AMF during processing of a
parallel admin_op.
+
2) how quicky applications respond to the csi callbacks.
Atleast to start with one redundancy model...
More later... Nagendra, Praveen would update on the details on the scenarios in
which AMF would still continue to do serial processing i.e. where existing
checks cannot be removed, etc....
(The bigger opportunity is also not to overlty complicate AMF by introducing
this adminop)
