Hi,

Which version of gluster you are using?

You can find which file is that using the following command
find <brickpath> -samefile <brickpath/.glusterfs/<first two bits of gfid>/<next 2 bits of gfid>/<full gfid>

Please provide the getfatr output of the file which is in split brain.
The steps to recover from split-brain can be found here,

HTH,
Karthik
