prashant kumar mishra commented on CLOUDSTACK-6797:
---------------------------------------------------

Tested on vmware , i was able to resize  data disk while is attached to vm  ,seen same problem
i a reported earlier .

-->since there is no check for max storage , available storage , threshold values , i was
able to resize it  more than total size of primary storage .

> =>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
