* Or even 60 TB SSD OSDs * Which Ceph release? * Are you using the bitmap or hybrid bluefs / BlueStore allocators? * Are you serving CephFS from them? * Autotuning or static BlueStore cache / osd_memory_target values? * What’s the RSS like on your OSDs? I’m seeing some unexpected behavior and would like some context from others’ experience. I suggest replying privately so as to not flood the list, and I’ll summarize. This will help me directly as well as evolve the hardware recommendations in the docs. Thanks. Anthony D’Atri Ceph Ambassador, Doc lead, etc.
