Hello Zheng
This is my initial email containing ceph -s and session ls info. I will send
cache dump shortly. Note that per John's suggestion, I have upgraded the
offending clients to 4.8 kernel, so my cache dump will be current with these
new clients.
Thanks,
Stephen

Clients are almost all idle, very little load on the cluster. I can see no
errors or warnings in the client logs when the file share is unmounted. Thx!

Thanks again John. I am installing 4.8.0-040800 kernel on my VM clients and
will report back. Just to confirm: there is no reason for this issue to try the
newer kernel on the mds node correct?

Thank you John. Both my Openstack hosts and the VMs are all running
4.4.0-38-generic #57-Ubuntu SMP x86_64. I can see no evidence that any of the
VMs are holding large numbers of files open. If this is likely a client bug, is
there some process I can follow to file a bug report?

Adding that all of my ceph components are version:

Openstack is Mitaka on Ubuntu 16.04x. Manila file share is 1:2.0.0-0ubuntu1
My scenario is that I have a 3-node ceph cluster running openstack mitaka. Each
node has 256gb ram, 14tb raid 5 array. I have 30 VMs running in o
I am using Ceph to back Openstack Nova ephemeral, Cinder volumes, Glance
images, and Openstack Manila File Share storage. Originally, I was using
ceph-fuse with Manila, but performance and resource usage was poor, so I
changed to using the CephFs kernel driver. Now however, I am getting messages
