Hi Anuradha,
I am doing the same which is mentioned in the link you shared and It has been resolved the issue.
But my question is if it is the split-brain scenario then why the command "gluster volume heal info split-brain"
not showing these files in the output even not the parent directory is present in split-brain.
Please find the requested logs

Hi Abhishek,
The files that are reporting i/o error have gfid-mismatch. This situation is called directory or entry split-brain. You can find steps to resolve this kind of split brain here : https://gluster.readthedocs.org/en/latest/Troubleshooting/split-brain/ .
Ideally, the parent directories of these files have to be listed in heal info split-brain output. Can you please get extended attributes of parent directories of the files that show i/o error (Same getfattr command that you previously used.) ?
