This does not sound really important to me and is kind of expected: the larger the cluster is, the more time you need to provision it. We just can't know the right timeout value in advance, as it also depends on hardware, networking, etc, not only on the cluster size.
I suggest we try to do a better job in 9.0 by tweaking timeout depending on the cluster size, maybe.
Please raise the importance, if you disagree.
