Description Matt Benjamin (redhat) 2019-01-29 17:57:25 UTC 
From upstream tracker issue:
"""
Objects deep in directory tree are not visible without first performing 'ls' on all of its subpaths. As an example I have put one object into rgw bucket:

s3cmd -c .s3cfg2 put test.txt s3://ganesha/a/b/c/d/f/g/h/i/j/k/l/test
s3cmd -c .s3cfg2 ls s3://ganesha/ --recursive
2018-06-14 15:40 5 s3://ganesha/a/b/c/d/f/g/h/i/j/k/l/test

The problem is that after mounting it with nfs the file is not immediately visible - I have to traverse all of the directories one by one.

root@ganesha-test:/# mount -o vers=4.1 test-server:/ /mnt/tmp/ -v
mount.nfs: timeout set for Thu Jun 14 17:41:18 2018
mount.nfs: trying text-based options 'vers=4.1,addr=192.168.0.14,clientaddr=192.168.0.16'
