Hello,
I have a Ceph Nautilus Cluster 14.2.1 for cephfs only on 40x 1.8T SAS disk (no
SSD) in 20 servers.

I often get "MDSs report slow requests" and plenty of "[WRN] 3 slow requests, 0
included below; oldest blocked for > 60281.199503 secs"
> HEALTH_WARN 2 MDSs report slow requests
> MDS_SLOW_REQUEST 2 MDSs report slow requests

After a few investigations, I saw that ALL ceph-osd process eat a lot of
memory, up to 130GB RSS each. It this value normal? May this related to
slow requests? Is disk only increasing the probability to get slow requests?
