Thank you for your answer. That's good news then as my meta pool is all SSD.

Another question popped up, for a small cluster like mine with 6 nodes, what are the best node types to co-locate an MDS service? I saw the cephadm orchestrator automatically placed them with the OSD nodes. Does this mean the optimal placement for an MDS service in my specific cluster would be on the OSD nodes itself?
