[Avra Sengupta]

Hi,

On investigating the logs attached to the bug, I see that the failure is 
in the following section:

[Directory not empty]

The system assumes(wrongly) that LVM is not mounted for the brick, and 
so goes ahead with deleting the brick path. But fails, because the 
directory is not empty. The same issue was happening when the original 
bug was filed, and was fixed with the fix mentioned. Would it be 
possible to have a look at your setup, so that we can get a better 
understanding of what is creating the issue, even with the fix.

Regards,
Avra
