            Bug ID: 1249499
           Summary: Make ping-timeout option configurable at a
                    volume-level
           Product: GlusterFS
           Version: mainline
         Component: rpc
          Assignee: kparthas at redhat.com

Description of problem:
A gluster volume can have ping-timeout values different from the default 42
secs. This can be done by setting network.ping-timeout option on the volume.

e.g,
# gluster volume set <VOLNAME> network.ping-timeout <preferred-value>

Currently, volume-set doesn't update the ping-timeout on running mounts.


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


How reproducible:
always


Steps to Reproduce:
1. Mount a gluster volume with default ping-timeout value.
2. Change the ping-timeout to a different value with the volume-set command
mentioned above.
3. Simulate a network disconnection using iptables(8) or attach gdb to one of
the brick processes.

Actual results:
The ping-timeout isn't updated on running mount processes.

Expected results:
The ping-timeout should take effect on running mount processes.
