-------------------------------------------------

             Summary: volume resize hsould not be allowed for detached volumes
                 Key: CLOUDSTACK-6797
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6797
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Storage Controller
    Affects Versions: 4.2.0, 4.4.0
            Reporter: prashant kumar mishra
            Priority: Critical
             Fix For: 4.4.0


=>since resize space is counted in allocated space even though it cant be attach to VM
, other storage operation will fail because threshold value 

If resize is allowed in volume  detach
==============================
1-since there is no check for how much can be increased , suppose user has resized it to 1000GB
2-when user try to attach volume to vm it will fail since available space is not sufficient
. 
3-even though user is not able to use the resized volume ,CS will count  1000GB in allocated
storage .
4-Dash will show allocated percentage >100%
5-Because threshold values , we cant  perform any operation to that PS


If resize is allowed online ( volume  Attach) state it will fail in first place and will not
cause any problem
