The default soft limit is an attribute of the volume that is specified as a percentage. The default soft limit for any volume is 80%.
When you do not specify the soft limit along with the hard limit, the default soft limit is applied to the directory or volume.
Configure the default soft limit value using the following command:
# gluster volume quota VOLNAME default-soft-limit soft_limit
For example, to set the default soft limit to 90% on test-volume run the following command:
# gluster volume quota test-volume default-soft-limit 90%
volume quota : success
Ensure that the value is set using the following command:
# gluster volume quota test-volume list
If you change the soft limit at the directory level and then change the volume's default soft limit, the directory-level soft limit previously configured will remain the same.
