Gluster users - Jul 2018 - Cannot list `.snaps/<snapname>` directory

Hello,

I have set up a test cluster with GlusterFS 4.1 and Ubuntu 16.04.5 and
I get the same behavior:
`ls .snaps/test/` hangs indefinitely in a getdents() system call.  I
can mount and list the snapshot
just fine with `mount -t glusterfs`, it's just the USS feature that is
not working.

Is this a known bug?  Any hints on how to work it around?

Thanks,
Riccardo

Let me try out the reproducible. By the time, can you try taking statedump of
the client process, snapd process, snapshot brick process. Please refer to
documentation [1] in case if you have any trouble in performing statedump
operation.
