Hallo, in my OpenStack Mitaka, I have installed the additional service "Manila" with a CephFS backend. Everything is working. All shares are created successfully:

When I try to mount the share into a client machine via the kernel driver:
mount -t ceph
os-storage01,os-storage02,os-storage03:/volumes/_nogroup/b27ad01a-245f-49e2-8974-1ed0ce8e259e
/tmp/test -o name=testclient,secret=AQDKO0xX6UgQNhAAe/9nJH1RGes0VzTZ+I04eQ==
I get the following error:
mount error 5 = Input/output error
When I use "ceph-fuse" without any further modifications, everything is working:
ceph-fuse /tmp/test --id=testclient --conf=/etc/ceph/ceph.conf
--keyring=/etc/ceph/ceph.client.testclient.keyring
--client-mountpoint=/volumes/_nogroup/b27ad01a-245f-49e2-8974-1ed0ce8e259e
I have tried to mount the "volumes" folder with kernel driver:
mount -t ceph os-storage01,os-storage02,os-storage03:/volumes /tmp/test -o
name=testclient,secret=AQDKO0xX6UgQNhAAe/9nJH1RGes0VzTZ+I04eQ==
It works so far, but when I try to list the folder's content, I get the
"Input/output error":
cd /tmp/test/_nogroup
ls
ls: cannot access '4f6f4f58-6a54-4300-8cb3-6d3a7debad61': Input/output error
ls: cannot access '83de097f-4fd4-4168-82e3-697dab6fa645': Input/output error

I am using Ubuntu Server 16.04 (Xenial) with the current kernel
"4.4.0-23-generic".
Can someone help me to get the mount working via the kernel driver?
