+++ This bug was initially created as a clone of Bug #1332517 +++

Description of problem:
The FS went to Read Only mode when files were deleted from the mount point.

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


How reproducible:
2/2

Steps to Reproduce:
1. create two volumes arbiter and arbiter nfs mount them using FUSE and nfs
respecitvely on same client.

2.create files using for (( i=1; i <= 100000; i++ ))

do
 echo dir$i
  mkdir scr$i
 echo file$i
  touch pt$i
 echo "dd command" $i
 dd if=/dev/urandom of=think$i count=5 bs=512k
done


3. start deleting files from both the mount points. 
Actual results:

the files got deleted from fuse mounted FS but READ ONLY FS error generated
while deleting the FS 
Expected results:
the files should be deleted from both the mount points without any errors.

*** UPDATED ***


Steps to Reproduce:
1. create two volumes arbiter and arbiter nfs mount them using FUSE and nfs
respectively on same client.

2.create files using for (( i=1; i <= 100000; i++ ))

do
 echo dir$i
  mkdir scr$i
 echo file$i
  touch pt$i
 echo "dd command" $i
 dd if=/dev/urandom of=think$i count=5 bs=512k
done


3. start deleting files from both the mount points. 
4. Bring down one of the replica brick using "init 0" command on the server.
5. ERRORS of ROFS start generating on the client when the deletion is in
progress.

Moving it to new as I haven't gotten a chance to look at it.
