Subject Re: deleteVolume is sync
Date Thu, 06 Jun 2013 15:25:11 GMT
So does it just need to be async, or is deleteVolume doing too much in
both moving the volume to destroy state and expunging? If I transition
a volume to 'Destroy' state, the storage cleanup thread comes along
and deletes it for me later, similar to how the VMs are expunged. This
seems preferable, because one could potentially undelete a volume
within the window.
