Description of problem:
======================
on my test cluster, I am seeing Input/Output error while issuing rm -rf simultaneously from 3 clients.

I have retried on just 2 clients and the issue still exists

However from single client I don't see the issue.



Version-Release number of selected component (if applicable):
===================
6.0.3 on rhel7.7 beta

How reproducible:
==================
always on my cluster

Steps to Reproduce:
1.created a 3 node brickmux enabled setup
2. created 1 1x3 volume
3. created 1 ec volume 22x(4+2) with other-eagerlock off
4. running IOs
5. under a directory I had created multiple directories and each hosting one file.
6. did rm -rf * from 2 or 3 clients 

Actual results:
==============
seeing EIO error
