Description of problem:
Suppose in a replace-brick operation, the source brick crashes, the replace-brick abort cannot be given (the command just hangs and then returns without giving any message), and further volume related operations such as volume stop fails saying replace-brick is in progress.

 gluster volume stop test
Stopping volume will make its data inaccessible. Do you want to continue? (y/n) y
Replace brick is in progress on volume test. Please retry after replace-brick operation is committed or aborted
[root@node130 src]# gluster volume stop mirror
Stopping volume will make its data inaccessible. Do you want to continue? (y/n) y
Replace brick is in progress on volume mirror. Please retry after replace-brick operation is committed or aborted
[root@node130 src]# 


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


How reproducible:

Whenever the source brick is crashed

Steps to Reproduce:
1. create and start a volume
2. mount the volume and do some i/o on the mount point
3. do replace brick
  
Actual results:

after source brick crash, replace-brick cannot be aborted (even after volume start force) and volume stop commands does not work.

Expected results:

after the source brick crash, replace-brick should be able to be aborted.
