Description of problem: Afr does dict_ref of the xattr_req that comes to it and deletes "gfid-req" key. Dht uses same dict to send lookup to other subvolumes. So in case of directories and more than 1 dht subvolumes, second subvolume till the last subvolume won't get a lookup request with "gfid-req". So gfid reset never happens on the directories in distributed replicate subvolume for 2nd till last subvolumes. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

This leads to successful setting of gfid when there are only two subvolumes in distribute. So increased number of replica subvolumes. Also increased number of directories.
