Description of problem:
While trying to bump up the op-version after upgrading a CNS setup from 3.9 to
3.10, the operation timed out.

sh-4.2# gluster volume set all cluster.op-version 31302
Error : Request timed out

However, after few minutes the op-version had got bumped up. So, there is no
functionality impact on the command getting timed out.

sh-4.2# gluster vol get all all
Option                                  Value                                   
------                                  -----
