[SOLVED] Crush rule: Error EINVAL: device class hdd does not exist

[vincentjanv]

Hi all,

in order to prepare for some new HDD's to supplement our SSD's , I'm trying to creating a new crush rule. This works for 'ssd' but not for 'hdd' .

ceph osd crush rule create-replicated replicated-hdd default host hdd

returns the following error:

Error EINVAL: device class hdd does not exist

Could it be because I do not have any HDDs installed at the moment, only SSDs?
