Oh, thank you. I've been poking through the Ceph docs, but somehow had not managed to turn up the wiki yet. What are the likely and worst case scenarios if the OSD journal were to simply be on a garden variety ramdisk, no battery backing? In the case of a single node losing power, and thus losing some data, surely Ceph can recognize this, and handle it through normal redundancy? I could see it being an issue if the whole cluster lost power at once. Anything I'm missing?
