+## Can not upload due to "no free volumes left"
+
+The symptom is similar to https://github.com/chrislusf/seaweedfs/issues/1631 where the logs show
+```

+```
+
+Each bucket will create one collection, with at least 7 volumes by default, and each volume is pre-allocated with a large size, usually 30GB.
+
+There are 2 ways to fix this. 
+* Reduce the global volume size by adjusting `-volumeSizeLimitMB` in `weed master` CLI option. 
+* Reduce the number of volumes to grow when a collection runs out of volumes. You can 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.
