QNAP Cinder driver: driver fails to create volume and snapshot in some case

[Chris Yang]

Step to reproduce :
1. Do one of the following operation:
(1) Create Volume
(2) Create Cloned Volume
(3) Create Snapshot
(4) Create Volume from Snapshot

Actual result : In most cases, it just works fine. Sometimes due to NAS busy or network delay, the volume or snapshot would fail to created.

Expect result : The volume or snapshot is successfully created.

I fixed this locally on the old driver (before they re-added it), it was an issue with not setting the timeouts on the requests, I set them to 10 seconds and it got fixed.

It probably is the same thing now, you just need to pass "timeout=10" (or a configurable option) in the call to "request.request" in "_get_response" method.

    QNAP: driver fails to create volume and snapshot in some case

    When NAS is busy or network delay, the volume or snapshot would
    fail to created. We fixed the logic of waiting NAS to creating
    LUN or snapshot.
