One of my clients is using
4.3.5-300.fc23.x86_64 (Fedora release 23)
while all the other clients reply on
3.10.0-327.4.4.el7.x86_64 (CentOS Linux release 7.2.1511)
Should I file report a bug on the RedHat bugzilla?

Are you using 4.1 or 4.2 kernel?
https://bugzilla.kernel.org/show_bug.cgi?id=104911. Upgrade to 4.3+
kernel or 4.1.17 kernel or 4.2.8 kernel can resolve this issue.
On the clients:
ceph-fuse --version
ceph version 9.2.0 (bb2ecea240f3a1d525bcb35670cb07bd1f0ca299)
MDS/OSD/MON:
ceph --version
ceph version 9.2.0 (bb2ecea240f3a1d525bcb35670cb07bd1f0ca299)
Exactly what changes are you making that aren't visible?
I am creating some new files in non-root folders.
What's the output of "ceph -s"?

Hi guys,
This is sort of rebuttal.
I have a CephFS deployed and mounted on a couple of clients via
ceph-fuse
(due to quota support and possibility to kill the ceph-fuse
process to avoid
stale mounts).
So the problems is that some times the changes made on one client
are not
visible on the others. It appears to me as rather random process.
The only
solution is to touch a new file in any particular folder that
apparently
triggers synchronization.
I've been using a kernel-side client before with no such kind of
problems.
So the questions is it expected behavior of ceph-fuse?
What version are you running on your servers and clients? Exactly
what
changes are you making that aren't visible? What's the output of
"ceph -s"?
We see bugs like this occasionally but I can't think of any recent
ones in
ceph-fuse -- they're actually seen a lot more often in the kernel
client.
