Description

Sometimes on our cluster fcntl lock requests get stuck. Restarting the MDS server does not help.
The mdsc file contains the following:

931466  mds0    setfilelock      #10000568fb1
931467  mds0    setfilelock      #10000568fab
931468  mds0    setfilelock      #10000568fa6

Locks and file access from another client to the same file still work.

I am using Ceph 0.94.2 together with Linux kernel 3.18.10 and the following patches:

ceph: exclude setfilelock requests when calculating oldest tid

ceph: fix dentry leaks

ceph: re-send requests when MDS enters reconnecting stage

ceph: introduce global empty snap context

Is there any other patch available, I might try?
