And bluestore should refuse to start if the configured
limit is > 4GB. Or something along those lines...
Just on this point - Bluestore OSDs will fail to start with an osd_max_object_size
>=4GB with a helpful error message about the Bluestore hard limit. I was mildly amused
when I discovered that luminous OSDs can start with osd_max_object_size = 4GB - 1 byte,
but mimic OSDs require it to be <= 4GB - 2 bytes to start without an error. I
haven't checked to see if nautilus OSDs require <= 4GB - 3 bytes yet.
Cheers,
Tom
