Description of problem:
One of Glusterfs(fuse) client crashes sometimes 

Version-Release number of selected component (if applicable):

How reproducible:
about once a week

Steps to Reproduce:
I'm sorry, I don't know

Actual results:
It crashed. It seems a core file was generated but it failed to be written to
the root dir.
And I think there's something wrong with this volume, but cannot be healed.

The attachment is copied from /var/log/glusterfs/mount-point.log of the client
I've got a statedump file but I don't know which section is related.

The volume(s) were created by gfs v3.8 @ centos6, and then I replaced the
servers by new servers with gfs v6.0 @ centos7, and upgraded their gfs to v6.1,
and then set cluseter.opver=60000
