With fuse client, I suspect you would need to do the following to let
readdir fop percolate through the stack:
1. mount client with --use-readdirp=no. This will bypass readdirplus in
2. Disable md-cache. md-cache by default converts all readdir operations
to readdirplus for its functioning.
3. Prevent dht from doing readdirp by default. While mounting, you could
pass --xlator-option "*dht.use-readdrip=no" to prevent readdir to
readdirp conversions in dht.
