Description M S Vishwanath Bhat 2012-03-13 10:56:03 UTC 
Description of problem:
rm -rf .glusterfs succeeded on nfs mount with zero exit status. But anyway .glusterfs was not removed from the back-end. 

Version-Release number of selected component (if applicable):
glusterfs-3.3.0qa27

How reproducible:
Often

Steps to Reproduce:
1. Create and start a single node distribute volume.
2. Mount via fuse and create some data.
3. Now run stat .glusterfs, rm -rf .glusterfs, cd .glusterfs etc. All of them will fail with No data available error. (currently)
4. Now umount the volume and mount again from nfs with nolock option.
5. Run rm -rf .glusterfs from the nfs mountpoint. The command succeeds.

Actual results:
The rm -rf .glusterfs succeeds with zero exit status. But .glusterfs is not removed from the back-end.

Expected results:
Ideally behavior 'rm -rf .glusterfs' should be consistent in fuse and nfs volume. Even it can't be same, there should be some error must be thrown to the user.

Additional info:

After above operations I checked in back-end and .glusterfs had a gfid set on it.
