Hi, To resolve the gfid split-brain you can follow the steps at [1]. Since we don't have the pending markers set on the files, it is not showing in the heal info. To debug this issue, need some more data from you. Could you provide these things? 1. volume info 2. mount log 3. brick logs 4. shd log
May I also know which version of gluster you are running. From the info you have provided it looks like an old version. If it is, then it would be great if you can upgarde to one of the latest supported release.
