I'm not a CephFS user, but I have had a few cluster outages. Each OSD has a journal, and Ceph ensures that a write is in all of the journals (primary and replicas) before it acknowledges the write. If an OSD process crashes, it replays the journal on startup, and recovers the write.
I've lost power at my data center, and had the whole cluster down. Ceph came back up when power was restored without me getting involved. You might want the paid support package. For extra piece of mind, you can get a paid cluster review, and an engineer will go through your use case with you.
