I forget.. have you tried the same with the kernel client? Not recently enough that I'd remember exactly what I did. However, I don't see how ceph-fuse could be the problem, given today's experiments. Here's what I just did (all with fuse): create snapshot check timestamps -> baseline unmount mount again check timestamps -> same restart mds check timestamps -> same unmount mount again check timestamps -> same moved a tree into dir check timestamps -> dir changed and snapshot unchanged, as expected unmount mount again check timestamps -> same restart mds check timestamps -> snapshot changed to dir's; its size too! After each umount, I checked that ceph-fuse was no longer running (it sometimes remains running for a while after umount completes) I've got full mds logs for this session, but they're kind of huge (860M).
