In some cases we have observed the time taken for a Cinder volume to attach to the conversion appliance can be longer than the current 60 seconds. Increase the timeout to 5 minutes.

While this seems a good attempt to avoid timeouts due to slow network or OpenStack interactions, I'd also raise the sleep amount (defaults is 2 seconds) in the with_timeout where this attach_timeout is used, for example to 5 seconds. This way, if Cinder/the appliance/whatever is overloaded, we will not overload it too with 2s bursts of queries. -- Pino Toscano
