Atomicity of multiple OfferOperations

Hi,

Can someone confirm whether whether a sequence of RESERVE, CREATE and
LAUNCH operations are perform atomic or not? For example, if master is
restarted in the middle, is it possible that RESERVE succeeded, but CREATE
for persistent volume failed?

Thanks.

It's not done atomically. Yes it's possible that only RESERVE succeeded and
CREATE was dropped due to a failure in the master or agent.
