We have a project using cephfs (ceph-fuse) in kubernetes containers. For us the throughput was limited by the mount point and not the cluster. Having a single mount point for each container would cap with the throughput of a single mount point. We ended up mounting cephfs inside of the containers. The initial reason we used kubernetes for cephfs was multi-tenancy benchmarking and we found that a single mount point vs 20 mount points all had the same throughput for our infrastructure (so 20 mounts points was 20x more throughput than 1 mount point). It wasn't until we got up to about 100 concurrent mount points that we capped our throughput, but our total throughput just kept going up the more mount points we had of ceph-fuse for cephfs.

_______________________________________________BogdanKind regards,Thank you, in advance!Do you have any recommendations (dos and don'ts) on this way of using CephFS?Hello, everyone!We have recently started to use CephFS (Jewel, v12.2.1) from a few LXD containers. We have mounted it on the host servers and then exposed it in the LXD containers.
