Describe the issue:Modification needed in creating block device snapshot section 

Describe the task you were trying to accomplish:Create a block device snapshot using doc. 

Suggestions for improvement:Procedure for creating snapshot should showcase 2 methods instead of mentioning 2 syntax in single procedure. This leads to file exists error since both below syntax are 2 different methods of creating a block device snapshot. 

rbd --pool POOL_NAME snap create --snap SNAP_NAME IMAGE_NAME
