Hi to all!
I have 2 questions regarding host buckets in the crush map;
1. The name of a "host bucket" is just a label (which can have an arbitrary value) or is used in some way or form (so it has to be a real short or full hostname)?
2. The second question is more complex, how to avoid, upon host reboot (or during the OSD activation), the creation of a new host bucket? I'll try to explain myself better.

So, the question remains, how to "pass" to ceph the correct host bucket name?
I think that the solution is to put "host=node01-int" in ceph.conf, but where? Under the "[osd]" sections ("[osd.*]"???) or I have to insert it under every single osd ([osd.12], [osd.13]...)?
Crush location can be defined in ceph.conf as: crush_location = root=default row=a rack=a2 chassis=a2a host=a2a1 Or the management can be disabled with (also in ceph.conf): osd_crush_update_on_start = false So, with this the question number 2 is answered, but for the first question I'm still not sure about it. Thanks Iztok
