Right, so the file OC_DEFAULT_MODULE is missing in this brick It's
parent directory has gfid fec0e4f4-38d2-4e2e-b5db-fdc0b9b54810. <br>
Goal is to do a stat of this file from the fuse mount. If you know
the complete path to this file, good. Otherwise you can use this
script [1] to find the path to the parent dir corresponding to the
gfid fec0e4f4-38d2-4e2e-b5db-fdc0b9b54810 like so:<br>
`./gfid-to-dirname.sh /data/myvolume/brick
fec0e4f4-38d2-4e2e-b5db-fdc0b9b54810`<br>

Try to stat the file from a new (temporary) fuse mount to avoid any
caching effects.<br>

<div>Thanks for your hints. Below you will find the
answer to your questions.<br>
</div>
<div><br>
</div>
<div>First I tried to start the healing process by
running:<br>
</div>
<div><br>
</div>
<div>gluster volume heal myvolume<br>
</div>
<div><br>
</div>
<div>and then as you suggested watch the output of the
glustershd.log file but nothing appeared in that log
file after running the above command. I checked the
files which need to be healing using the "heal
<volume> info" command and it still shows that
very same GFID on node2 to be healed. So nothing
changed here.<br>
</div>
<div><br>
</div>
<div>The file
/data/myvolume/brick/.glusterfs/indices/xattrop/29e0d13e-1217-41cc-9bda-1fbbf781c397
is only on node2 and not on my nod1 nor on my
arbiternode. This file seems to be a regular file
and not a symlink. Here is the output of the stat
command on it from my node2:<br>
</div>
<div><br>
</div>

</div>
</blockquote>
<div><br>
</div>
<div>Okay, link count of 2 means there is a hardlink
somewhere on the brick. Try the find command again. I
see that the inode number is 2798404, not the one you
shared in your first mail. Once you find the path to
the file, do a stat of the file from mount. This
should create the entry in the other 2 bricks and do
the heal. But FWIW, this seems to be a zero byte file.<br>

<div>I tried to find the real file on my brick

<div>So my question here is, is it possible that
this is a stale file which just forgot to get

for some unknown reason? If yes is it safe for
me to delete these two files? or what would be
the correct process in that case?<br>
</div>
</blockquote>
<div>The 'xattrop-6fa...' is the base entry. gfids
of files that need heal are hard linked to this
entry, so nothing needs to be done for it. But you
need to find out why '29e0d13...' is not healing.
Launch the heal and observe the glustershd logs
for errors. I suppose the inode number for
.glusterfs/29/e0/29e0d13e-1217-41cc-9bda-1fbbf781c397
is what is 8394642. Is
.glusterfs/29/e0/29e0d13e-1217-41cc-9bda-1fbbf781c397
a regular file or symlink? Does it exist in the
other 2 bricks? What is the link count (as seen
from stat <file>)?<br>
