Hi all,


Back in Luminous Dev and RC, I was able to do this:


`ceph osd crush class create myclass`


so I could utilise the new CRUSH device classes feature as described here: http://ceph.com/community/new-luminous-crush-device-classes/



and in use here: http://blog-fromsomedude.rhcloud.com/2017/05/16/Luminous-series-CRUSH-devices-class/


Now I'm on Luminous LTS 12.2.1 and my custom device classes are still seen in:


`ceph osd crush class ls`


`ceph osd tree` and so on. The cluster is working fine and healthy.


However, when I run `ceph osd crush class create myclass2` now, it tells me the command doesn't exist anymore.


Are we not meant to create custom device classes anymore?


Regards,

Linh
