-The other side is to reduce the number of volumes to create. In `weed shell`, you can configure this way:
-```
-$ weed shell
-> fs.configure -locationPrefix="/buckets/" -volumeGrowthCount=3 -apply
+In addition, you can also configure the per bucket storage this way in `weed shell`:
 
-```
+> fs.configure -locationPrefix=/buckets/ -volumeGrowthCount=1 -apply

+This will add 1 physical volume when existing volumes are full. If using replication, you will need to add more volumes.
