The trickiest part of this is to detect we run on HCI. Hi Bara, Yes, I agree. Beyond what's there in BZ#1611850, you could mention that this parameter "osd_memory_target" is automatically tuned by ceph-ansible, based on host memory. The default value is 4GiB. This is set differently for HCI and non-HCI setups("is_hci" is the ceph-ansible configuration parameter, that needs to provided to differentiate between setups, default value is false). We also have different safety_factor values for hci and non-hci, which come into play when ceph-ansible calculates the value of osd_memory_target. Thanks, Neha Hi Bara, Answering your questions in https://bugzilla.redhat.com/show_bug.cgi?id=1611850#c14 here. Yes, the user can configure osd_memory_target using ceph-ansible, by setting it in all.yml, same applies to is_hci. Guillaume, is there any other caveat worth mentioning?
