Subject [jira] [Commented] (CLOUDSTACK-2181) 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

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-2181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13781773#comment-13781773
] 

prashant kumar mishra commented on CLOUDSTACK-2181:
---------------------------------------------------

for now we don't support scaling up on kvm, and  for xen and vmware you can follow the 4.2
admin guide 

> 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

> 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
