BTW, I think it should be in 3.10.1 also.
We have back ported to 3.10.1 too.
If possible upgrade to 3.11.0 and see if you are seeing this messages or not.

<blockquote>
Whenever we do some fop on EC volume on a file, we check the xattr also to see if the file is healthy or not. If not, we trigger heal.
lookup is the fop for which we don't take inodelk lock so it is possible that the xattr which we get for lookup fop are different for some bricks.
This difference is not reliable but still we are triggering heal and that is why you are seeing these messages.
We have fixed it in latest release https://review.gluster.org/16468
Now, we check if fop actually needs heal or not.

Hi ,
I need some clarification for below error msg in the glustershd.log file. What is this msg? Why is this showing up?. currently using glusterfs 3.10.1
when ever I start write process to volume (volume mounted thru fuse) I am seeing this kind of error and glustershd process consumes some percentage of cpu until write process completes.
