Bug 2089188

Describe the issue:

Martin Bukatovic, May 16, 8:57 PM
Another stupid question: is it possible to define buckets in a cluster hierarchy and place hosts under these buckets directly via ceph orch yaml file?

Martin Bukatovic, May 16, 8:59 PM
I don't see it in https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/5/html-single/operations_guide/index#advanced-service-specifications-and-filters-for-deploying-osds_ops so the answer likely is "no". But I wonder if I haven't missed anything.

I think you'd have to use a crush location hook or ceph osd crush set commands

it would be kinda neat to be able to do that in a osd service definition, though

so you could have a different osd service definition per rack or something

thanks for confirmation

This was a feature that we had in ceph-ansible(RHCS4) where you could specify on the ansible inventory the crush location  of the OSDs per host, when I asked some time ago about being able to set the crush map with cephadm the Idea was to make it available in the 5.1/5.2 timeframe, not sure if implementing this feature in cephadm has advanced

Martin Bukatovic, May 16, 9:09 PM
ah, good to know that it's already at least considered

@Daniel Parkes btw do you have a BZ/JIRA/upstream issue for this?

Daniel Parkes, Wed 12:04 PM
Yes, it has been merged upstream some time ago, so it's documented: https://docs.ceph.com/en/latest/cephadm/host-management/#setting-the-initial-crush-location-of-host   ,   the ceph tracker was: https://tracker.ceph.com/issues/44284 , so you can actually use it with RHCS 5.1
