[Gluster-users] gluster 3.7.9 permission denied and mv errors

Regarding the ENOTEMPTY error I need some more information:
1) Are there multiple clients running the same script or performing rmdir on the directory that complained?
2) Was there a rebalance running when you saw the error?
3) Before you ran the second rmdir that successfully removed the directory was there an 'ls' or similar fop performed on the directory?

I am running into two problems (possibly related?). 

1) Every once in a while, when I do a 'rm -rf DIRNAME', it comes back with an error: 
rm: cannot remove `DIRNAME` : Directory not empty 

If I try the 'rm -rf' again after the error, it deletes the directory. The issue is that I have scripts that clean up directories, and they are failing unless I go through the deletes a 2nd time. 

2) I have different scripts to move a large numbers of files (5-25k) from one directory to another. Sometimes I receive an error: 
/bin/mv: cannot move `xyz` to `../bkp00/xyz`: File exists 

The move is done using '/bin/mv -f', so it should overwrite the file if it exists. I have tested this with hundreds of files, and it works as expected. However, every few days the script that moves the files will have problems with 1 or 2 files during the move. This is one move problem out of roughly 10,000 files that are being moved and I cannot figure out any reason for the intermittent problem. 

Setup details for my gluster configuration shown below.
