Marcus Sorensen commented on CLOUDSTACK-6797:
---------------------------------------------

No, and I'm unable to work within the community at the moment due to contractural obligations.
I will say that I think blocking volume resize for detached volumes is not the right solution,
we just need to add the proper capacity checks.

> =>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
