prashant kumar mishra created CLOUDSTACK-2181:
-------------------------------------------------
Summary: Scale down is allowed when one resource(say cpu) is
being scale up and other resource (say ram)is being scale down ;but not allowed
when both resources are being scaledown
Key: CLOUDSTACK-2181
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2181
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server, XenServer
Affects Versions: 4.2.0
Reporter: prashant kumar mishra
Priority: Minor
Fix For: 4.2.0
Scale down is not allowed as per FS and condition is valid when you try to
scale down both resources (cpu and RAM); but not valid when you try to scale up
one resource and scale down other resource
Steps to repo
------------------
1-Deploy a vm with small instance SO
2-create three service offering say a1, a2 ,a3 (a1{cpu=1
GHz,ram=256};a2{cpu=500MGz,ram=512};a3{cpu=300 MGz,ram=256})
3-try to scaledown to service offering a3 (it will fail with message "Only
scaling up the vm is supported, new service offering should have both cpu and
memory greater than the old values")
4-Try to scaleup to SO a1(successful)
5-Try to scaleup to SO a2 from a1(successful)
Expected
--------------
AS per FS scale down should not be allowed in any case
