   Let's say when s3G started all buckets are created under volume s3v.
   
   Now different S3G's started using different volumes, now when the user wants 
to use the bucket in o3fs, now he is not sure which volume to use. As said in 
the PR description this can cause this kind of issue.  I understood the use 
case of you, have mentioned, and also we are not totally eliminating this, if 
someone is advanced user and knows what he is doing, they can still use this, 
but they will see the warning. (But it is not documented, I think this can be 
addressed with a new page with your proposal)
   
   And also one more point, using a single volume for S3G buckets came to 
eliminate a command which was there before `ozone s3 path`, thinking that is an 
extra burden and now the user needs to know the volume name from this command. 
(And also volume names are cryptic) now with this feature, we will be back to 
the same issue.
   
   So, to avoid this, might be admin need to give one S3G URL and the volume 
used underneath it to users. (And admin can go ahead and create the volumes and 
provide appropriate permissions)
   
   
   Okay coming back to the comment, to get this in are you proposing we need to 
remove the warning which we have added in the code?
   
   ```
         LOG.warn(OZONE_S3_VOLUME_NAME + " is deprecated. Consider using bucket 
" +
             "link command to access volume/buckets created via ozone shell " +
             "through S3Gateway and also to access buckets created by S3Gateway 
" +
             "version less than or equal to 0.5.0");
   ```
