I was looking at ceph/crush/builder.c crush_make_tree_bucket() function,

Right, so let's talk about how we get into that situation:
1) Our existing OSDMap is bad.
a) We were never correct
b) ...we went bad and didn't notice?
2) The Incremental we got is bad.
a) It's not the original

Hi,
Currently on Ubuntu with Upstart when you invoke a restart like this:
$ sudo restart ceph-osd-all
It will restart all OSDs at once, which can increase the load on the system

It's better to restart

FYI, this sounds like an issue the userspace client (and possibly the
actual rbd class?) had as well: it looked at the HEAD parent_overlap
