<pre wrap="">"gluster volume info" and "gluster vol status" would help in us debug faster.
However, coming to gfid mismatch, yes the file "abbreviations.log" (I assume the other brick copy also to be " abbreviations.log" and not "breviations.log" ....typo mistake?) is in gfid mismatch leading to IO error(gfid splitbrain)
Resolving data and metadata splitbrains are not recommended to be done from backend brick.
But in case of a GFID splitbrain(like in file abbreviations.log), the only method available is resolving from backend brick
You can read more about this in <a class="moz-txt-link-freetext" href="http://gluster.readthedocs.io/en/latest/Troubleshooting/split-brain/?highlight=gfid">http://gluster.readthedocs.io/en/latest/Troubleshooting/split-brain/?highlight=gfid</a> (Fixing Directory entry split-brain section)
(There is a bug already existing to resolve gfid splitbrain using CLI )

I've read that doc, however I'm not sure what to do with bits that
are not mentioned in that doc. Which is:<br>
when some xattr does not exist on one copy but does on the other,
like:<br>
<br>
3]$ getfattr -d -m . -e hex .vim.backup/.bash_profile.swp<br>
# file: .vim.backup/.bash_profile.swp<br>
security.selinux=0x73797374656d5f753a6f626a6563745f723a756e6c6162656c65645f743a733000<br>
trusted.afr.USER-HOME-client-0=0x000000010000000100000000<br>
trusted.afr.USER-HOME-client-5=0x000000010000000100000000<br>
<br>
2]$ getfattr -d -m . -e hex .vim.backup/.bash_profile.swp<br>
# file: .vim.backup/.bash_profile.swp<br>
security.selinux=0x73797374656d5f753a6f626a6563745f723a64656661756c745f743a733000<br>
trusted.afr.USER-HOME-client-5=0x000000010000000100000000<br>
trusted.afr.USER-HOME-client-6=0x000000010000000100000000<br>
<br>
unless the doc talks about it and I've gone (temporarily) blind, but
if it's does not it would be great to include more scenarios/cases
there.<br>
many thx.<br>

<pre wrap="">Hi,
Can you help us with more information on the volume, like volume status and volume info
One reason of "transport endpoint error" is the brick could be down
Also, i see that the syntax used for healing is wrong.
You need to use as below:
gluster v heal <vname> split-brain source-brick <brick path> <filename considering brick path as />
In yourcase if brick path is "/G-store/1" and the file to be healed is "that_file" , then use below syntax (in this case i am considering "that_file" lying under the brick path directly"
gluster volume heal USER-HOME split-brain source-brick 10.5.6.100:/G-store/1 /that_file

<pre wrap="">
that was that, my copy-paste typo, it does not heal.
Interestingly, that file is not reported by heal.
I've replied to - GFID Mismatch - Automatic Correction ? -
I think my problem is similar, here is a file the heal
actually sees:
$ gluster vol heal USER-HOME info
Brick
