kernel-3.10.0-327.*.el7 comes from RHEL 7.2. (although I don't know what "ug" means in your version, there?) kernel-3.10.0-493.el7 ships in the RHEL 7.3 Beta. You need a RHEL subscription to access the RHEL betas (CentOS doesn't build them). - Ken On Thu, Sep 29, 2016 at 7:19 AM, Kenneth

Hi, If you are using the kernel client, I would suggest trying something newer than 3.10.x. I ran into this issue in the past, but it was fixed by updating my kernel to something newer. You may want to check the OS recommendations page as well:

Dear Ceph experts, We meet a nasty problem with our CephFS from time to time: When we try to list a directory under CephFS, some files or directories do not show up. For example: This is the complete directory content: # ll /cephfs/ies/home/mika drwxr-xr-x 1 10035 11 1559018781 Feb 2
