Ok! So I'll update the RFC to support multiple storage pools and to
use the Tasks API to handle the pause/resume/cancel operations.
Well, Aline and I found a problem with this proposal. Currently, the
REST API always redirects "POST" requests in a Collection to the
function "<colletion-name>_create". In our case, if we send "POST
/storagepools/<pool-name>/storagevolumes/download", that would be
redirected to the backend function "storagevolumes_create". There is no
way to redirect those requests to different functions (like, ideally,
"storagevolumes_download" and "storagevolumes_upload").
So I see two options from here:
1) Use the first API proposed by Aline: "POST
/storagepools/<pool-name>/storagevolumes". By looking at the parameters
(i.e. whether 'url' starts with "file://" or "[http|ftp]://")
we can
tell if the operation is download or upload.
2) Remodel the control code to support multiple actions when
POST'ing to a Collection.
