[ceph-users] Cephfs snapshot work

Are there any existing fuzzing tools you'd recommend? I know about ceph osd
thrash, which could be tested against, but what about on the client side? I
could just use something pre-built for posix, but that wouldn't coordinate
simulated failures on the storage side with actions against the fs. If
there is not any current tooling for coordinating server and client
simulation, maybe that's where I start.
