I agree operationally, but FWIW ISTR that in Pacific …. or maybe it was Octopus …. the default min_size was changed to K from K+1. Perhaps that doesn’t affect existing pools without intervention? With small clusters especially, there are other reasons to favor more hosts, even if they have to be smaller. Ways to get there include 1U servers instead of 2U, not initially filling all drive slots. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
