CCing Ravi (arbiter) , Poornima and Raghavendra (parallel readdir)
I had a quick look at the files you sent across. To summarize the issue, you see empty linkto files on the mount point.
From the logs I see that parallel readdir is enabled for this volume:
performance.readdir-ahead: on
performance.parallel-readdir: on
There was a similar issue reported earlier [1] and fixed as part of [2]. Which version of gluster are you running? Poornima and Raghavendra, can you take a look and see if it is the same issue?
An interesting observation - the value of the trusted.glusterfs.dht.linkto xattr is different on the one of the bricks of the replica set for some of the files(Ravi, any idea why ?)
