<p>Can you tell me how can I fix that ?If that helps I don't mind
deleting the whole folder snooper, I have backup.<br>

<br>
The steps listed in "Fixing Directory entry split-brain:" of
<a class="moz-txt-link-freetext" href="https://gluster.readthedocs.io/en/latest/Troubleshooting/split-brain/">https://gluster.readthedocs.io/en/latest/Troubleshooting/split-brain/</a>
should give you an idea. It is for files whose gfids mismatch but
the steps are similar for directories too.<br>
If the contents of the snooper is same on all bricks , you could
also try directly deleting the directory from one of the bricks and
immediately doing an `ls snooper` from the mount to trigger heals to
recreate the entries.<br>
Hope this helps<br>
Ravi<br>

<div class="moz-cite-prefix">What does the mount log say when
you get the EIO error on snooper? Check if there is a gfid
mismatch on snooper directory or the files under it for all 3
bricks. In any case the mount log or the glustershd.log of the
3 nodes for the gfids you listed below should give you some
idea on why the files aren't healed.<br>

<p>But actually in the brick on each server the folder

<p>I tried rebooting the servers, restarting gluster after
killing every process using it but it's not working.</p>
<p>Has anyone already experienced that ? Any help would be
nice.<br>

<br>
Can you share the output of `gluster volume heal
<volname> info` and `gluster volume heal
<volname> info split-brain`? If the second command
shows entries, please also share the getfattr output from
the bricks for these files (getfattr -d -m . -e hex
/brick/path/to/file).<br>
