Bug 818519

Description of problem:

Suppose replace-brick is given on a volume. After the replace-brick is done (replace-brick status command says migration complete), kill all the gluster processes (i.e. glusterfsd, glusterfs, glusterd or the machine can be rebooted).

Now start the gluster processes (starting glusterd).

Now if replace-brick abort or replace-brick commit command is given, then it just gets blocked for 2 minutes and then returns without giving any output.

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


How reproducible:

Always

Steps to Reproduce:
1. Start replace-brick on a running volume and wait till the migration is complete
2. killall all the gluster processes (glusterfsd, glusterfs, glusterd or reboot the machine)
3. Restart the gluster processes and give replace-brick commit/abort.
  
Actual results:

replace-brick abort/commit commands gets blocked for 2 minutes and then return without any output

Expected results:

Replce brick commands should work properly.

Additional info:


 5:     option transport.socket.keepalive-time 10
  6:     option transport.socket.keepalive-interval 2
  7:     option transport.socket.read-fail-log off
  8: end-volume
