Hello,
I saw that parallel-readdir was an experimental feature in GlusterFS version 3.10.0, became stable in version 3.11.0, and is now recommended for small file workloads in the Red Hat Gluster Storage Server documentation[2]. I've successfully enabled this on one of my volumes but I notice the following in the client mount log:
[2018-01-23 10:24:24.048055] W [MSGID: 101174] [graph.c:363:_log_if_unknown_option] 0-homes-readdir-ahead-1: option 'parallel-readdir' is not recognized

The GlusterFS version on the client and server is 3.12.4. What is going on?
