Created attachment 612689 [details] Dump of the process that claims split-brain. Description of problem: I had a file that was reporting split-brain. I deleted the file and the .glusterfs counterpart from two of the replica 3 servers. After a lookup() was performed on the file, it self-healed. Hash sums and extended attributes confirm that the file is clean. The client is still reporting a split-brain condition even though the file is healed. I mounted the volume on a second directory and could read the file through that mount.
